Abstract:

Viola odorata is a viola family flowering plant native to Europe and Asia. This is a small, hardy, herbaceous, perennial plant. It is also known as sweet violet and English violet. Numerous pharmacological properties of this flowering plant include anticancer, antibacterial, anti-inflammatory, antioxidant and antipyretic properties. Previous literature review of different parts of Viola odorata resulted in detection of different chemical constituents such as flavonoids (Quercetin, kaempferol), glycosides (Rutin) and terpenoids (stigma sterol). Stigmasterol was detected using TLC and GC-MS in this study. It was isolated from Viola odorata using preparative layer chromatography. HPLC and FTIR analysis confirmed the isolated Stigmasterol

Abstract:

This study aimed at examining the effect of supercritical carbon dioxide (ScCO2) extraction on the subsequent extraction of the Viola odorata polar bioactive components. The raw material was firs submitted to ScCO2 extraction for the extraction of the lipophilic fraction. Then the exhausted raw material was subjected to ultrasound-assisted extraction (UAE) and microwave-assisted extraction (MAE) in order to extract the polar components. ScCO2 extraction was performed under the pressure of 300 bar and at a temperature of 40 °C for 4 hours. In order to see the effect of ScCO2, the UAE and MAE (50% aqueous ethanol solution as solvent) were conducted on both exhausted (residue-after the ScCO2) and unexploited raw materials. Also, the impact of the various UAE and MAE conditions was tested. The UAE was conducted on two different temperatures (40 and 50 °C) at the constant extraction time (40 and 20 min). MAE was conducted on two different extraction powers (470 and 800 W) and at the constant extraction time (10 min). The results were focused on the content of total phenols, total flavonoids and antioxidant activity of the obtained extracts. The yield during the ScCO2 process was 1.43% (w/w). It was noted that the extracts obtained by applying UAE and MAE after the ScCO2 were noticeably richer in the content of total phenols. UAE conditions of 40 °C and 20 min showed the highest yield of total phenols, recording 70.38 mg GAE/g DE, while the MAE at the power of 470 W achieved 11.89% higher yield of polyphenols in residue extracts. The antioxidant activity has also been in correlation with the concentration of polyphenols.

Abstract:

Background. The metabolic syndrome increases the risk of different diseases such as type 2 diabetes. The prevalence of metabolic syndrome has rapidly grown and affected more than 230 million people worldwide. Viola odorata is a traditionally used plant for the treatment of diabetes; however, its mechanism to manage diabetes is still unknown. Purpose. This study was designed to systematically assess the mechanism of action of Viola odorata in diabetes. Methods. An extensive literature search was made to establish an ingredient-target database of Viola odorata. Of these, targets related to diabetes were identified and used to develop a protein-protein interaction network (PPIN) by utilizing the STITCH database. The obtained PPIN was assessed through Gene Ontology (GO) enrichment analysis based on ClueGO plugin. Results. According to the acquired data, there were about 143 chemical constituents present in Viola odorata having 119 protein targets. Of these, 31 targets were established to give the pharmacological effect against diabetes. The UniProt database was used for screening of 31 targets, out of which Homo sapiens contained 22 targets. Ultimately, 207 GO terms, grouped into 41 clusters, were found by gene analysis, and most of them were found to be linked with diabetes. According to findings, several proteins including TP53, BCL2, CDKN1A, 1L6, CCND1, CDKN2A, and RB1 have a significant role in the treatment of diabetes by Viola odorata. Conclusion. The possible activity of Viola odorata in the management of diabetes may be mediated by several molecular mechanisms, including the glutamine metabolic process, IRE1-mediated unfolded protein response, and pentose metabolic process.

Abstract:

The traditional healers made significant use of the Viola odorata of the Violaceae family for its many ethnopharmacological uses. The phytochemical composition and in vitro antioxidant activity of solvent extracts from Viola odorata shoots were studied, and the antibacterial potential of the optimized extract was also examined. The Soxhlet apparatus was used to extract phytochemicals from shoots in four different solvents, including n-hexane, butanol, methanol, and water. High-performance liquid chromatography (HPLC) was used to analyze the stigmasterol profile of V. odorata shoots. The extracts were found to contain alkaloids, flavonoids, terpenoids, saponins, and phenolics, all of which were found in significant amounts in the methanolic extract. The methanolic extract also showed the highest radical scavenging activity (79.23 ± 0.44 %). TLC and HPLC profiling of methanolic extract revealed a considerable amount of stigmasterol in the shoots of Viola odorata. HPLC analysis of the methanolic shoot extract of the plant revealed the presence of 0.009 µg mL-1 stigmasterol. Optimized Methanolic extract showed respectable in-vitro antimicrobial activity against Bacillus subtilis (2.6 ± 0.41 mm zone of inhibition), E. coli (3.4 ± 0.71 mm zone of inhibition), and Candida albicans (3.5 ± 0.48 mm zone of inhibition). The outcomes demonstrated that the methanolic shoot extract of Viola odorata from Shikari Devi Wildlife Sanctuary, Himachal Pradesh, India, is a valuable herb for further screening and might be prepared for in-vivo animal studies.

Abstract:

In the present study, ethanolic extract of Banafsha i.e., Viola odorata (Violaceae) and its gel formulations was evaluated for its sun protection activity by ultraviolet spectroscopy method. The phytoconstituents like flavonoids, phenolics present in Viola odorata may be responsible for scavenging action on UV-induced reactive oxygen species. Extraction of aerial parts of the plant was done in the Soxhlet apparatus using ethanol as solvent. 1ml, 2ml, and 4ml of ethanol extract (200µg/ml) of the plant were used to formulate three gels (F1-F3) using Carabopol 940, 0.5% Methyl paraben, 0.2% Propyl paraben, Propylene glycol 400 and Triethanolamine. Mansur et al. UV spectrophotometric method was used to investigate the in vitro SPF of the Viola odorata ethanolic extracts (100&200µg/ml) and its formulated gels (F1-F3). Physical parameters like color, appearance, spreadability, pH, homogeneity, viscosity were determined to evaluate formulated gels. Based on the calculated SPF value, F3 formulation was chosen for the stability study. Ethanolic extract of Viola odorata (100 µg/ml and 200µg/ml) have SPF value 4.05±0.07 and 11.66±0.04, respectively. Gel formulations (F1-F3) containing 1, 2,4ml of 200µg/ml of ethanol extract have SPF values about 2.89±0.11, 4.20±0.08, and 5.63±0.07, respectively. The SPF values determined to confirm the capacity of gels to absorb UV radiation. No significant alterations in physicochemical parameters and SPF values were observed during the stability evaluation of F3 gel. Results proves that Viola odorata is a safe alternative which can be used over harmful chemical sunscreens used now a days in the industry and in the future plant can be explored for active component for better protection against sun rays.

Abstract:

Violets (Viola) are potential candidates for aroma-focused breeding research. Though most Viola species and modern hybrids lack fragrance, the genus contains a famously scented species, Viola odorata L. This species and its cultivars are genetic resources of aroma traits that could be used to investigate the selection for and transmission of fragrance during the breeding process. Despite its famous scent, however, the floral volatile emissions of V. odorata have not been characterized using modern headspace techniques. Using static and dynamic headspace volatile collection methods and gas chromatography–mass spectrometry, the floral volatile emissions of V. odorata were temporally and developmentally characterized. Floral volatiles were also sampled from 10 V. odorata cultivars, three Parma violet cultivars, five violet species, and one hybrid, and variation in scent among these violets was investigated. Total volatile emissions in V. odorata were highest from 0600 HR to 1900 HR, suggesting a diurnal pattern of emission. Volatile emissions also varied over the developmental lifespan of the flower, with the highest emission of individual and total volatiles occurring, in general, from stages 0 or +1 to stages +3 or +4. Floral scent qualitatively and quantitatively differed among assorted violets. The floral volatile emissions of V. odorata exhibit temporal and developmental variation. Compared with the other violet species in this study, sweet violets are intensely fragrant. The quantity and quality of floral scent differs among V. odorata cultivars, providing genetic variation from which selections could be made in a fragrance-focused breeding program.

Abstract:

Introduction: Finding non-systemic antipyretic option in cancer patients who simultaneously receive several other drugs seems be logical. This study was designed to evaluate complementary therapy with Viola odorata L. oil for fever control in febrile neutropenic children. Methods and Materials: In a randomized placebo controlled clinical trial, 41 febrile children were divided into two groups. Children in the active drug group received viola oil (20 drops) to be rubbed on the peripheral margin of the patient umbilicus. Primary outcome measure of the study was the mean axillary temperature in the 30, 60, and 240 minutes after the intervention. Results: The mean temperature reduced significantly in the viola group after 30 minutes of administration (p =0.005), while there was no significant change in the placebo group (p =1.00). The number of patients who received paracetamol as the rescue treatment was significantly lower in the viola group than that in the placebo group (5 vs. 17, p =0.001). Conclusion: The results of our study showed the safety and efficacy of complementary therapy with Viola odorata L. oil for fever control in febrile neutropenic children during hospital course.

Abstract:

Viola odorata L. oil is frequently recommended in the aromatherapeutic literature for treating respiratory, urinary, and skin infections; however, antimicrobial evidence is lacking. In addition, in aromatherapy, combinations of essential oils are predominantly utilized with the goal of achieving therapeutic synergy, yet no studies investigating the interaction of essential oil combinations with V. odorata oil exists. This study thus aimed to address these gaps by investigating the antimicrobial activity of three Viola odorata oil samples, sourced from different suppliers, independently and in combination with 20 different commercial essential oils, against micro-organisms involved in respiratory, skin, and urinary tract infections associated with global resistance trends. These pathogens include several of the ESKAPE pathogens (Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa and Enterobacter spp.) The chemical profile of the oils was determined using gas chromatography coupled with mass spectrometry. The minimum inhibitory concentrations (MIC) were determined using the broth micro-dilution method. The interactive profiles for the combinations were assessed by calculating the fractional inhibitory concentration index (ΣFIC). The main compounds varied across the three samples, and included phenethyl alcohol, isopropyl myristate, 2-nonynoic acid, methyl ester, α-terpineol, α-cetone, and benzyl acetate. The V. odorata oil samples displayed overall poor antimicrobial activity when tested alone; however, the antimicrobial activity of the combinations resulted in 55 synergistic interactions where the combination with Santalum austrocaledonicum resulted in the lowest MIC values as low as 0.13 mg/mL. The frequency of the synergistic interactions predominantly occurred against Klebsiella pneumoniae, Pseudomonas aeruginosa, Acinetobacter baumannii, and Enterococcus faecium with noteworthy MIC values ranging from 0.25–1.00 mg/mL. This study also reports on the variability of V. odorata oils sold commercially. While this warrants caution, the antimicrobial benefit in combination provides an impetus for further studies to investigate the therapeutic potential.

Abstract:

Viola odorata, or sweet violet, is a plant rich in phytochemicals like flavonoids, tannins, saponins, and cyclotides, known for their antioxidant and antimicrobial properties, making it a promising candidate for anti-ulcer therapy. We aimed to evaluate the anti-ulcer potential of a methanolic extract of Viola odorata (MEVO) using in-vitro and in-vivo ethanol-induced gastric ulcer in rats. Fordtran’s and Vatier’s model were used as an in-vitro model which showed that MEVO at 250 mg/ml and 500 mg/ml effectively neutralized acid. The zones of inhibition of MEVO at 250 mg/ml and 500 mg/ml were found to be 9.33 mm and 11.66 mm respectively, compared to amoxicillin (14.33 mm). In the ethanol-induced ulcers rat model, the ulcer index of MEVO (500 mg/ml) was found to be 3.66, while the standard group had an ulcer index of 2.83. These results suggest that V. odorata extract possesses acid-neutralizing and antibacterial properties in both in-vitro and in-vivo settings, indicating its potential for anti-ulcer therapy.

Abstract:

The aim of the study was to evaluate the postharvest longevity of cut leaves of Viola odorata and determine their usefulness as a florist green. The research also involved the study of the influence of chemical compounds used as plant preservatives on the longevity of leaves of V. odorata. The leaf stalks of V. odorata were soaked in water or conditioned in a 200 mg·dm−3 solution of 8–hydroxyquinoline sulphate, or a 50 or 100 mg·dm−3 solution of gibberellic acid. After one day, the leaves were kept in water or 200 mg·dm−3 of 8–hydroxyquinoline sulphate. The leaves of V. odorata had a longevity of about 31 days in water. Both the conditioning in gibberellic acid and 8–hydroxyquinoline sulphate and the maintenance in 8–hydroxyquinoline sulphate reduced the vase life of cut V. odorata leaves. The application of conditioners resulted in a significantly greater reduction of the leaf mass. The Soil Plant Analysis Development value of the leaves was best affected by conditioning them in 100 mg·dm−3 gibberellic acid followed by keeping them in water. Cut leaves of V. odorata with water treatment may be used as a florist green.

Abstract:

The primary objective of this study was to assess the antimicrobial activities of various polar and nonpolar solvent extracts derived from the leaves of Viola odorata. The disc diffusion method was employed to test the antimicrobial susceptibility against a diverse range of pathogenic microorganisms, including Escherichia coli, Erwinia carotovora, Klebsiella pneumoniae, Bacillus subtilis, Pseudomonas aeruginosa, Salmonella typhi, Staphylococcus aureus and the fungus Candida albicans. The results indicated that isobutanol and ethyl acetate fractions exhibited significantly higher antimicrobial activity compared to petroleum ether, crude, chloroform and aqueous fractions. Among the tested bacteria, E. carotovora was the most susceptible bacterium to all the extracts of V. odorata, whereas S. typhi demonstrated the highest resistance. The isobutanol extract inhibited the proliferation of E. carotovora by 62 % at a concentration of 2 mg disc-1, while the ethyl acetate extract achieved 53% inhibition under the same conditions. Additionally, our findings revealed that the overall antimicrobial activity of V. odorata leaves was consistently effective against both Gram-positive and Gram-negative bacterial strains.

Abstract:

Viola odorata, sometimes called English violet or sweet violet, is a herbaceous perennial plant that belongs to the Violaceae family. It has long been used for its medicinal properties in a variety of traditional medical systems, such as Persian, Ayurvedic, and Unani medicine.  The plant, which has a rich phytochemical profile that includes flavonoids, alkaloids, saponins, tannins, and phenolic compounds, is native to Europe and Asia. These components help to explain the plant's remarkable anti-inflammatory, antifungal, antibacterial, and antioxidant qualities.  Research has shown that it is effective in treating a variety of illnesses, including asthma, diabetes, liver problems, cardiovascular disease, respiratory disorders, and sleeplessness.  The plant's sedative, expectorant, diuretic, and hepatoprotective properties are also recognised.  Research in the preclinical and clinical stages has validated its safety and efficacy at therapeutic dosages. The conservation and sustainable cultivation of Viola odorata are crucial due to its medicinal significance and economic potential in both traditional and modern phytotherapy.

Abstract:

In this study there are demonstrated for the first time in albanian literature the palynomorphologic characteristics of two types of plants (Centaurea epirota and Viola epirota), collected in Zagoria valley, Gjirokastra region, in Albania. To carry out the study, light microscopy was used and it was concluded that the pollen grains of Centaurea epirota were 3 colporate, isopolar, with radial symmetry. In the polar view, the pollen grains have a circular triangular shape while in the equatorial view they have a compressed oval shape. Exine appeared scabrate. Viola epirota consisted of 3-4 colporate, sometimes even 5 colporate pollen grains. In the polar view, the pollen grains had a circular shape of 3 or 4 angles, sometimes even 5 angles while in the equatorial view they had an elliptical shape. Exine appeared granulate. To see the impact of ecological factor and the method of laboratory processing of pollen grains, the size of the new species studied was compared with the size of the pollen grains of Centaurea cyanus and Viola alba, Viola odorata and Viola arvensis, taken from the native literature.

Abstract:

Viola odorata is traditionally used in the management of gastrointestinal, respiratory and vascular disorders. The present study was undertaken to validate its folkloric uses. The application of V. odorata to spontaneous contractions in isolated rabbit jejunum preparation exerted relaxant effect through decrease in magnitude and frequency of contractions. Moreover, it also caused relaxation of K+ (80 mM)-induced contractions and shifted the Ca2+ concentration response curves toward right in isolated jejunum similar to verapamil (standard Ca2+ channel blocker), confirming Ca2+ channel blocking activity. V. odorata also caused relaxation of carbachol (1 µM)- and K+ (80 mM)-induced contractions in isolated rabbit tracheal preparations comparable to verapamil, reflecting that observed relaxant effect may be the outcome of anti-muscarinic and/or Ca2+ channel blocking activities. It also exerted relaxant effect on phenylephrine (1 µM)- and K+ (80 mM)-induced contractions in isolated rabbit aortic preparations thus providing rationale for its folkloric uses to treat diarrhea, asthma and hypertension.

Therefore, an experiment was conducted to study the effect of the different doses of nitrogen and spacing on Viola odorata Linn. (Banafsha) in mid hill zones of Himachal Pradesh in Randomized Block Design with 3 replications. Treatments consisted of 4 levels of nitrogen (0, 60, 90, 120 kg/ha) and 5 row spacing (10 x 10 cm, 15 x 15 cm, 20 x 20 cm, 25 x 25 cm and 30 x 30 cm), respectively. Full does of Phosphorus and Potassium (60 kg/ha each) were applied at the time of transplanting. 1000 seed weight was observed maximum for N 120 kg/ha. Maximum value of fresh weight of flower was observed at 10 x 10 cm spacing, while number of leaves per plant, pod diameter and 1000 seed weight were found highest at the spacing of 25 x 25 cm. Application of 120 kg N/ha and spacing of 25 x 25 cm produced significantly higher pedicel length, fresh weight of flowers, while 1000 seed weight was found maximum for N 90 kg/ha at a spacing of 25 x 25 cm.

Abstract:

In Viola odorata two inferior anthers have connective appendages (nectaries) projecting into the corolla spur. Nectaries are approx. 4 mm long, elongate, with the top of the nectary bending to the lateral wall of the spur. In the top part and in the abaxial surface of middle part of the nectary all cells have papillae. Nectar is secreted through the modified stomata distributed mainly in the top of nectary The nectary consists of single-layered epidermis, nectary parenchyma and subnectary parenchyma. Features of the nectary parenchyma cells, like dense cytoplasm containing numerous mitochondria and large nuclei, are connected with high metabolic cell activity. The vascularization includes both phloem and xylem. A slight amount of starch in the nectary cells, the profusion of plasmodesmata connecting secretory cells and the presence of vascular bundles suggest that sugars secreted in the nectar were delivered by the phloem sap.

Abstract:

This study was aimed to determine the composition of essential oil contained in Viola odorata flowers and leaves. As well as assessing the cytotoxic effects of this oil on cancer cells and its antioxidant properties. A GC-Mass analysis was conducted to reveal essential oil components in flowers and leaves. For testing the antioxidant capacity of flowers and leaves oil, DPPH (1,1 Dyphenyl-2-picrylhydrazyl), resazurin dye, and hydroxyl were used. An in vitro study was conducted using lung cancer (A549) and breast normal (MCF-10) cell lines with concentrations of 25, 50, 100, 200, and 300 µl/ml of V. odorata L. essential oil. According to the results, essential oils derived from flowers and leaves contain different components in terms of quality and quantity. At a concentration of 300 µl/ml, the results showed that flowers' essential oil was highly antioxidant (98.16 %, 92.47%, 94.00 %) when combined with DPPH, resazurin dye, and hydroxyl, respectively. There was variation in cytotoxic effects on cancer cells based on oil concentrations and sources (flowers and leaves). In conclusion, the A549 cell line was significantly affected by flower oil than by leaves oil. The highest effect of flower oil was observed at a concentration of 300 µl/ml.
