Abstract:

Staphylococcus aureus is a nosocomial problem that can cause skin infections. Treatment of skin infections can be done by using citronella (Cymbopogon nardus) which is antibacterial because it contains compounds such as flavonoids, steroids, terpenoids, saponins, and essential oils. This study aims to determine the antibacterial power of Cymbopogon nardus leaf starch essence against Staphylococcus aureus inhibition zone. This type of research is a laboratory experiment using a post-test only control group design. The results showed that the extract of Cymbopogon nardus leaves with a concentration of 5%, 10%, 15%, and 20% with positive control of ampicillin had different inhibitory zona against Staphylococcus aureus bacteria. The conclusion is that the concentration of Cymbopogon nardus leaf starch is the most effective and forms an inhibition zone with the largest average (16.28), namely a concentration of 20%.Keywords: Antibacterial, lemongrass, Staphylococcus aureus

Abstract:

Grasses are a valuable group of monocotyledonous plants, used as nourishing foods and as remedies against diseases for both humans and livestock. Phytochemical profiles of 13 medicinal grasses were quantified, using spectrophotometric methods and ultra-high-performance liquid chromatography–tandem mass spectrometry (UHPLC–MS), while the antioxidant activity was done using DPPH and ferric-reducing-power assays. The phytochemical analysis included the total soluble phenolic content, flavonoids, proanthocyanidins, iridoids and phenolic acids. Among the 13 grasses, the root methanolic extracts of Cymbopogon spp., Cymbopogon nardus and Cenchrus ciliaris contained the highest concentrations of total soluble phenolics (27–31 mg GAE/g DW) and flavonoids (4–13 mg CE/g DW). Condensed tannins and total iridoid content were highest (2.3 mg CCE/g DW and 3.2 mg HE/g DW, respectively) in Cymbopogon nardus. The most common phenolic compounds in the grass species included ρ-coumaric, ferulic, salicylic and vanillic acids. In the DPPH radical scavenging assay, the EC50 values ranged from 0.02 to 0.11 mg/mL for the different grasses. The best EC50 activity (lowest) was exhibited by Cymbopogon nardus roots (0.02 mg/mL) and inflorescences (0.04 mg/mL), Cymbopogon spp. roots (0.04 mg/mL) and Vetiveria zizanioides leaves (0.06 mg/mL). The highest ferric-reducing power was detected in the whole plant extract of Cynodon dactylon (0.085 ± 0.45; r2 = 0.898). The observed antioxidant activity in the various parts of the grasses may be due to their rich pool of phytochemicals. Thus, some of these grasses provide a source of natural antioxidants and phytochemicals that can be explored for their therapeutic purposes.

Abstract:

The growth inhibitory effect of Cymbopogon nardus (L.) W. Watson var. nardus essential oil on Aspergillus niger (Van Tieghem) mycelium was determined on agar medium. The mycelium growth was completely inhibited at 800 mg/L. This concentration was found to be lethal under the test conditions. Essential oil at 400 mg/L caused growth inhibition of 80% after 4 days of incubation, and a delay in conidiation of 4 days compared with the control. Microscopic observations were carried out to determine the ultrastructural modifications of A. niger hyphae after treatment with C. nardus essential oil. The main change observed by transmission electron microscopy concerned the hyphal diameter and the hyphal wall, which appeared markedly thinner. These modifications in cytological structure might be caused by the interference of the essential oil with the enzymes responsible for wall synthesis which disturb normal growth. Moreover, the essential oil caused plasma membrane disruption and mitochondrial structure disorganization. The findings thus indicate the possibility of exploiting Cymbopogon nardus essential oil as an effective inhibitor of biodegrading and storage-contaminating fungi.Key words: essential oil, antifungal agent, hyphal ultrastructure, cell wall, scanning electron microscopy, transmission electron microscopy.

Abstract:

Cymbopogon citratus and Cymbopogon nardus are two species of Cymbopogon that are commonly cultivated in Indonesia. Studies have shown Cymbopogon activities and potencies for development for various diseases including diabetic treatment. Both C. citratus and C. nardus have long history for culinary and medicinal herb in Indonesia and therefore have a sustainable commercial production that will support their development for functional food ingredient. This work provides a study about industrial observation in several herbal industries along with literature review of herbal industries condition in Indonesia as a benchmarking study to summarize the required research or technical development of Cymbopogon as functional food ingredients. During industrial observation it was shown that Cymbopogon usage in herbal industries were more popular as flavorings rather than for its functionalities. The industrialobservation to several reputable herbal industries showed that despite the similar infrastructure used for extraction and pulverization method, the industries might have different supply procurement and quality requirement, extraction principle, product character and quality control, and therefore market character. The literature review have shown several studies of Cymbopogon functionalities in organic solvents, empirical uses of Cymbopogon as medicinalherbs in water extract, optimization in Cymbopogon cultivation. Heavy studies have been done in the extraction, usage, and characterization of essential oils from Cymbopogon. Many literature showed formulation of Cymbogon for culinary purpose but there are yet formulation based on its functional activities. Both industrial observation and literature review called in the requirement of more study of activities and stabilities of the Cymbopogon aqueous andethanolic extracts, optimization of post-harvest processing, extraction, and further processing to produce Cymbopogon ingredients based on activities and efficiency, and the determination of active fraction/compound(s) responsible for the activity and formulation of food that will enable the usage direction of functional food ingredients.

Abstract:

Introduction: Cymbopogon nardus is a strong aromatic plant with relevant medicinal properties due to its essential chemical compounds and its potential therapeutic effects. This study was aimed to evaluate the antimicrobial activities of citronella essential oil against several oral pathogens and to identify the volatile compounds. Methods: The essential oil of C. nardus was purchased from Excellent Wisdom Sdn. Bhd., Malaysia. The source of raw material was collected from Malacca, the southern region of Malaysia, and the company made its taxonomic identification. An experimental in-vitro study was conducted on the essential oil processed from C. nardus genus Cymbopogon of Poaceae family. The in-vitro antimicrobial activities of C. nardus essential oil were evaluated against Streptococcus mutans (ATCC 25175), Streptococcus sobrinus (ATCC 33478), and Candida albicans (ATCC 10231) using agar well diffusion assay. The identification of the volatile compounds was performed using gas chromatography-mass spectrometry (GC-MS). Results: The C. nardus essential oil exhibited inhibitory activity against C. albicans at the concentration of 6.25%, whereby the inhibitory activity against S. mutans and S. sobrinus began at the concentration of 25%. The antimicrobial activity of C. nardus essential oil was statistically significant at the concentration of 50% in all tested pathogens. The GC-MS analysis of the C. nardus essential oil revealed the presence of few constituents, which include monoterpenes, diterpenes, sesquiterpenes and phenolic compounds. Monoterpenes were the major identified terpenoids and contributed to 54.45% of the total volatile composition. The main identified monoterpenes were citronellal (11.35%), z-Citral (11.34%), β-Myrcene (6.70%), and β-Trans-ocimene (6.03%), which was the first time β-Myrcene and β-Trans-ocimene was found in high percentage. Conclusion: C. nardus essential oil is an active antibacterial agent against several oral pathogens, and the percentages of active volatile compounds are different within different origins.

Os óleos essenciais são produtos do metabolismo secundário de plantas e são conhecidos por possuir diferentes propriedades biológicas, incluindo atividades antimicrobianas, podendo agir como antibacteriano, antifúngico e antiviral. Objetivou-se nesta pesquisa avaliar a atividade antibacteriana de óleos essenciais sobre cepas de Escherichia coli e Pseudomonas aeruginosa isoladas de alimentos. Foram utilizados os óleos de Eucalyptus globolus (eucalipto comum), Prunus amygdalus (amêndoa), Cymbopongon nardus (citronela), Rosmarinus officinalis (alecrim), Cinnamomum zeylanicum (caneleira), Cymbopogon citratus (capim limão), Citrus limon (limão), Caryophyllus aromaticus (cravo). Foram utilizadas dez linhagens de E. coli e dez de P. aeuriginosa. Para determinação da Concentração Inibitória Mínima (CIM) dos óleos essenciais foi utilizado o método de microdiluição em placas de 96 poços. As concentrações bactericidas mínimas (CBM) foram determinadas a partir dos resultados da CIM. Designou-se como CBM a concentração mínima em que não ocorreu crescimento bacteriano. Verificou-se que todos os óleos essenciais apresentaram atividade antibacteriana, no entanto os óleos de E. gobulus e R. officinalis foram mais ativos frente a E. coli (CBM=3,13%), e menos eficazes frente a P. aeruginosa (CBM=25%), enquanto que o de C. nardus apresentou atividade biológica frente a P. aeruginosa na concentração de 6,25%. A atividade antimicrobiana dos óleos essenciais testados aponta a possibilidade de desenvolver agentes antimicrobianos eficientes e de baixo custo no controle de E. coli e P. aeruginosa.

Abstract:

Cymbopogon nardus (C. nardus) or fragrance lemongrass is a member of Gramineae family which is well known for its citronella oil content that is commonly used as a natural fragrant oil, in insect repellents, as well as in beauty, household and perfumery products. C. nardus is one of the unique herbs that has been widely discussed in Malay Medical Manuscript and has been consumed by Malay practitioner as it possesses various anti biological activities such as anti fungal, anti bacteria and anti-inflammatory. In traditional system of medicine among Malay traditional people, C. nardus has been used for the treatment of fever, muscle pain, and many kinds of illness. Various uses shown by this herb and the tendency of high application of the herb among Malay society has led us to study C. nardus according to the scientific perspective. Therefore, the objectives of this study are to identify the morphology of C. nardus and its application from Malay traditional’s perspectives, as well as to determine the active compounds present in the herb through scientific findings. Two different parts of leaves and stems of C. nardus were extracted using steam distillation method for 2 hours. The chemical composition of citronella oil was determined by Gas Chromatography-Mass Spectrometry (GC-MS). An amount of 0.55 % and 0.024 % of citronella oil were extracted from leaves and stems parts, respectively. The main compositions of oil extracted from the leaves part are citronellol (41.4 %), methyleugenol (80.2 %), citronellal (39.7 %), D- limonene (40 %) and geraniol (36.5 %). Meanwhile, the extraction from the stems composed of α-Himachalene (45.34%), Citronellol acetate (48.2 %), cis-Geraniol (57.8 %) and endo- Borneol (26.2 %). Thus, it can be concluded that C. nardus leaves extraction yield higher citronella oil content as compared to stems and consist of different main chemical compositions between the two parts.

Abstract:

Plant extracts have gained popularity recently, for their importance as potential antioxidative and antimicrobial agents. These properties have been attributed to their phytochemical content. The extraction solvent and the plant part are among the factors that influence the yield of these phytochemicals This study was therefore undertaken to investigate the antimicrobial and antioxidant activities of extracts of the leaf and stem of Ocimum sanctum (holy basil) and Cymbopogon nardus (citronella grass); two commonly occurring plants in South East Asia. The extracts were obtained by solvent extraction using water, methanol and ethanol. The percentage yield, antimicrobial activity, antioxidant activity and high-performance liquid chromatography (HPLC) analysis was investigated. The organic extracts yielded a higher percentage recovery of phytochemicals compared to the water extracts. HPLC analysis revealed the presence of chlorogenic acid in all extracts; rutin only in the leaf extracts and the citronella grass leaf extract contained both rutin and gallic acid. Antimicrobial assays were performed using the agar well diffusion method with tetracycline as positive control. Basil extracts exerted a greater inhibitory growth on both S. aureus and E. coli. S. aureus was found to be more susceptible to the presence of plant extracts. Water extracts did not display any zones of inhibition. The DPPH (2,2-diphenyl-1-picrylhydrazyl) assay was used to study the antioxidant effect with Vitamin C (0.1mg/ml) as positive control. The results indicated that the Basil leaf extracts possessed greater antioxidant potential compared to the stem. The study concludes that organic extracts of O. sanctum and C. nardus possess pharmaceutical properties.

Abstract:

The Aedes aegypti mosquito can develop an immune system against the insecticide used. Control efforts with the use of insecticides are no longer effective if the target insects have become resistant. So there needs to be an effort to overcome the insect resistance that is targeted. Citronella grass is an herbal plant that can be used as an ingredient in vegetable pesticides. The leaves and stems are distilled to produce essential oil known as citronella oil. This research is about studying the effects of citronella oil against the resistance of the vector carrier for dengue fever, namely Aedes aegypti. The detection of citronella essential oil (Cymbopogon nardus L.) by Thin Layer Chromatography showed a reduction in UV254 visualization (Rf 0,68). The resistance test showed that the mortality percentage of adult mosquitoes Aedes aegypti exposed to 0.03% alphacymethrin was 73,7% resistant criteria (<90%). The mortality percentage of adult mosquitoes Aedes aegypti exposed to Alphacypermethrin (0,03%) and citronella oil was 2,5% each; 5%; 7,5% and 10% with treatment time 15 respectively, namely 18,7%, 50,7%, 70,7% and 82,7%; the treatment time of 30 minutes consecutively is 62,7%, 89,3%, 96% and 97,3% and the treatment time is 60 minutes respectively, namely 93,3%, 98,7%, 98,7% and 100%. There was an increase in the percentage of mosquito deaths exposed to the combination of alphacypermethrin and citronella oil, compared to those without citronella oil, this indicates that mosquitoes are more susceptible and resistance has decreased due to exposure to citronella oil.

Abstract:

Effectiveness Of Various Concentrations Of Lemongrass Leaf Extract Lotion (Cymbopogon nardus) As Repellent Of Aedes aegypti Mosquitoes. Dengue Hemorrhagic Fever (DHF) is a disease caused by dengue virus which is transmitted through the bite of the Aedes aegypti mosquito. Vector control efforts that are popular in the community are using chemical insecticides. The use of insecticides can cause mosquito resistance and cause poisoning in humans. Then effective controls need to be developed to avoid these impacts. Safe control of health and environmentally friendly is to use natural repellent derived from plants, one of which is lemongrass leaf (Cymbopogon nardus). The purpose of this study is to know the effectiveness of various concentrations of lemongrass leaf extract lotion (Cymbopogon nardus) as repellent of Aedes aegypti mosquitoes. This type of research is an experimental laboratory with the research design of The Posttest - Only Controlled Group Design. The research method by hand control and treatment is presented in a cage containing 25 Aedes aegypti mosquitoes for 6 hours with repetition 10 times each hour. The results showed that a concentration of 20% had an average protective capacity of 82.8%, a concentration of 40% had an average protective capacity of 95.0%, an concentration of 80% had an average protective capacity of 98.1% and lotion repellent from chemicals with the brand "X" has an average protection capacity of 88.6%. The results of the Kruskal Wallis analysis proved significant with p = 0.003 α (0.05), so there were significant differences in the protective power. The conclusion of the study was that the lemongrass leaf extract lotion was effectively used as a repellent of Aedes aegypti mosquitoes at a concentration of 40% and 80% because the protective power value 90% even though it had been used for 6 hours.

AbstractObjectivesNatural products commonly used in traditional medicine, such as essential oils (EOs), are attractive sources for the development of molecules with anti-proliferative activities for future treatment of human cancers, e.g., prostate and cervical cancer. In this study, the chemical composition of the EO from Cymbopogon nardus was characterized, as well as its antioxidativeproperties and anti-inflammatory and antiproliferative activities on LNCaP cells derived from prostate cancer.MethodsThe chemical composition of the EO was determined by GC/FID and GC/MS analyses. The antioxidative properties were assessed using DPPH radical scavenging assay and ABTS+• radical cation decolorization assay, and the anti-inflammatory capacity was determined by the inhibition of the lipoxygenase activity. Antiproliferative activity was evaluated by MTT assay.ResultsCollectively, our data show that the major constituents of C. nardus EO are citronellal (33.06 %), geraniol (28.40 %), nerol (10.94 %), elemol (5.25 %) and delta-elemene (4.09 %). C. nardus EO shows modest antioxidant and anti-inflammatory activity compared to the standard galic acid. C. nardus EO exhibits the best antiproliferative activity on the prostate cancer cell line LNCaP with an IC50 of 58.0 ± 7.9 μg/mL, acting through the induction of the cell cycle arrest.ConclusionsThis study has determined that C. nardus EO efficiently triggers cytotoxicity and pens a new field of investigation regarding the putative use of this EO in vivo.

Abstract:

The use of natural compounds as food preservatives is becoming increasingly popular as it is perceived positively by consumers. Among these substances, essential oils have attracted great interest owing to their antioxidant and antimicrobial properties. However, several challenges impair the use of essential oils in food products, such as their degradation or loss during food processing and storage, the strong aroma, even at low concentrations, which may negatively affect the sensory characteristics of food. In this context, the development of nanoformulations able to stabilize essential oils may represent a smart solution to this issue. The aim of the study was to evaluate the efficiency of alginate-based nanoformulations enriched with lemongrass (Cymbopogon nardus) essential oil (LEO) and Tween 80 against several fungi namely Penicillium expansus, Aspergillus niger and Rhizopus spp. Firstly, the flow behavior of systems at different concentrations of alginate (1%, 2% and 3% w/w) were studied. Then, emulsion-based nanoformulations at different concentrations of lemongrass essential oil in the range of 0–2% w/w were stabilized by a fixed amount of Tween 80, characterized and tested for their antifungal activity. Our results showed that the best nanoformulation able to inhibit Rhizopus spp., Penicillium expansum and Aspergillus niger, for at least 10 days, was constituted by 1% alginate/1.5% LEO/1% Tween 80. Hence, the incorporation of essential oil into nanoformulation systems may represent a valid alternative to overcome the disadvantages that limit the commercial application of essential oils.

Abstract:

Lemongrass traditionally can be used as a mixture of water bath for rheumatic patients, antiseptic medicine, headache reducer, unbend the leech bite and overcome insect bite, but, the bioactivity potential of citronella lemongrass still remains unknown. The content of citronella lemongrass is known to have secondary metabolites such as flavanoid, phenolic, and terpenoid. The aim of this study is to determine the LC50 value (Lethality Concentration 50) in the root, stem, and leaves part of citronella lemongrass. Citronella lemongrass is extracted with maceration method using 96% ethanol solvent. Rendement value of leaf extract is greater than the value of stem and root extract, which is equal to 8.69% for stem extract, 3.73% for root extract and 9.70% for leaves extract. A toxicity test was performed by using the BSLT method, shrimp larvae were inserted into the test solution with each different solution concentration. LC50 values were obtained based on the calculation of percent mortality of shrimp larvae by using probit analysis. LC50 ethanol extract 96% of citronella lemongrass leaf is 67.841 μg/ml, citronella lemongrass stem is 31.604 μg/ml and citronella lemongrass root is 10.489 μg/ml. LC50 value shows that ethanol extract 96% of root, stem, and leaf of citronella lemongrass have no bioactivity potential due to the value of LC50 is greater than 1000 μg/ml.

Abstract:

Uno de los grupos de insectos que causan daños y molestias en los seres vivos, son los mosquitos, además son vectores de enfermedades. Generalmente, el método más utilizado para evitar los problemas ocasionados por estos insectos es la aplicación de productos químicos sintéticos; sin embargo, su mal manejo y abuso, causan resistencia a estos productos y que cada vez existan más organismos. Con base a lo anterior en el presente trabajo se evaluó la efectividad repelente del aceite esencial de citronela (Cymbopogon nardus L.), inf lamable e incombustible, la planta Pelargonium citrosum (Van) y un gel comercial a base de extractos vegetales sobre adultos del mosquito Culex quinquefasciatus (Say). En Ciudad Universitaria de la Benemérita Universidad Autónoma de Puebla y durante los meses de junio a septiembre de 2010, se realizaron cinco ensayos con diferente número de tratamiento. El aceite comercial de citronela (C. nardus), tanto inf lamable e incombustible, funcionó ef icazmente como repelente contra C. quinquefasciatus, resultando mejor la combinación de ambos aceites. El gel elaborado a base de laurel, cedrón y lavanda, es un repelente natural que solo permite que se posen entre 14 y 23 mosquitos y la planta P. citrosum actúa como repelente de los mosquitos a distancias de 9 m2.

O objetivo foi avaliar o efeito dos óleos essenciais de Mentha piperita, Cymbopogon nardus e Eucalyptus globulus, na qualidade sanitária e fisiológica de sementes e mudas de Schinus molle L. As sementes foram tratadas com os óleos essenciais nas concentrações de 10%, em 1 μL g-1 de sementes, 20% , em 2 μL g-1 de sementes, 30%, em 3 μL g-1 de sementes e o tratamento controle. Após os tratamentos, as sementes foram avaliadas pelo teste de sanidade, utilizando-se o método do papel de filtro (“blotter test”) e pelo teste de germinação, onde as sementes foram colocadas entre substrato vermiculita. Para as contagens, foram consideradas sementes germinadas e sementes mortas. Na avaliação da qualidade das mudas, mediu-se o comprimento da parte aérea, raízes, altura total e diâmetro do colo. A utilização dos óleos essenciais de citronela e menta reduziu a incidência dos diferentes patógenos presentes nas sementes de S. molle. O óleo essencial de menta a 20% e 30 % favoreceu a germinação das sementes. O óleo essencial de eucalipto, em qualquer concentração, aumentou o crescimento das mudas.Evaluation of essential oils in health and physiological quality of Schinus molle seeds and seedlingsThe objective was to evaluate the effect of Mentha piperita, Cymbopogon nardus and Eucalyptus globules essential oils, in sanitary and physiological quality of Schinus molle L. seeds and seedlings. The seeds were treated with essential oils at concentrations of 10%, on 1 μL g-1, 20%, on 2 μL g-1, 30% , on 3 μL g-1 and control. After treatments, seeds were evaluated by sanity test, using filter paper method (“blotter test”) and by germination test, where the seeds were placed between vermiculite substrate. For counts, sprouted and dead seeds were considered. Shoot length, root, total height and stem diameter were measured for seedlings evaluation. The use of citronella and mint essential oils reduced the incidence of different pathogens in S. molle seeds. Mint essential oil at 20% and 30% were effective to promote seeds germination.

Abstract:

O uso de compostos vegetais como alternativa para controle de fitopatógenos tem recebido destaque em pesquisas que visam viabilizar métodos de manejo sustentável na agricultura. Fungos como Didymella bryoniae, Pyricularia grisea, Rhizoctonia solani e Sclerotium rolfsii são importantes por causarem grandes perdas na produção. Neste contexto, objetivou-se avaliar a fungitoxicidade de óleos vegetais na inibição do crescimento de fungos fitopatogênicos. Os ensaios foram conduzidos em delineamento inteiramente casualizado com 13 tratamentos (Cymbopogon nardus, C. citratus, Lippia alba, Eugenia dysenterica, Caryocar brasiliense, Azadirachta indica, A. indica - comercial, Ageratum conyzoides, Jatropha curcas, Eucalyptus sp., Mentha piperita, Tiofanato metílico e Testemunha) e quatro repetições. Para a avaliação da fungitoxicidade, foram distribuídos 1,5μ L mL-1 dos tratamentos na superfície do meio de cultura BDA (batata-dextrose-ágar). Os óleos essenciais de Eucalyptus sp., M. piperita, L. alba, C. nardus e C. citratus inibiram o crescimento de P. grisea. D. bryoniae não apresentou crescimento micelial apenas no óleo de C. citratus. Os fungos R. solani e S. rolfsii não cresceram quando submetidos aos tratamentos de óleos essenciais de M. piperita, L. alba, C. nardus e C. citratus.

Abstract:

Advanced extraction method such as simultaneous ultrasonic–hydrodistillation (UAE–HD) extraction method has been proved to increased extraction yield of plant material yet the application of this method in the preparation of metal nanoparticles has not been studied. In this study, Cymbopogon nardus (C.N) extracted via UAE-HD extraction method was used to synthesis silver (Ag) nanoparticles. XRD and TEM analysis confirms the formation of spherical shape Ag nanoparticles with size ranging between 10-50 nm. FTIR spectra suggest the presence of bioactive compounds in the C.N leaves extract that may responsible to the stabilization and reduction of Ag ions (Ag+) to metallic Ag nanoparticles (Ag0). The TPC analysis successfully proved that huge number of phenolic compound greatly involved in the nanoparticles synthesis process. Next, the catalytic activity of the synthesized Ag nanoparticles was tested towards the degradation of 2,4-Dicholorophenoxyacetic acid herbicide with remarkable degradation performance up to 98%. Kinetic study confirms that surface reaction was the controlling step of the catalytic process. Copyright © 2019 BCREC Group.

Abstract:

Acne is a disease of the skin that often occurs during adolescence until adulthood. Acne is characterized by the appearance of several signs, namely blackheads, pustules, papules, cysts and nodes in the neck, face, upper arms, back and chest area. Acne is also a skin disease that affects more than 85% of adolescents around the world. Although not life-threatening, acne can affect a person's quality of life by giving a psychological effect that is bad for the sufferer in the form of a person's way of judging, responding to and looking at his condition and situation. The purpose of this study was to determine the inhibitory power of citronella extract (Cymbopogon nardus) on the growth of Propionibacterium acnes bacteria. The study was conducted with experimental methods with the posttest design only group design controls conducted at the Microbiology Lab at the Faculty of Medicine, University of Prima Indonesia and the Pharmacy and Toxicology Lab at the Faculty of Pharmacy, University of North Sumatra. The results showed that lemongrass leaf extract had a inhibitory effect on the growth of Propionibacterium acnes bacteria with various concentrations of 20, 40, 60, 80 and 100%. The higher the concentration of fragrant lemongrass extract, the better the inhibition power.
