Abstract:
The aim of this present investigation was to analyze bioactive compounds, as well as demonstrate the antioxidant activities of nine cultivars of Australian lupin species accompanied by observing the effect of domestic heat processing on their antioxidant activities adopting in vivo and in vitro approaches. Gas chromatography mass spectroscopy (GC-MS) analysis was performed for profiling bioactive compounds present in lupin cultivars. Multiple assay techniques involving quantification of polyphenolics, flavonoids and flavonol, electron transfer (ET) based assay, hydrogen atom transfer (HAT)-based assay and in vivo assays were performed. The major compounds found were hexadecanoic acid methyl ester, 9,12-octadecadienoic acid methyl ester, methyl stearate, lupanine,13-docosenamide and 11-octadecenoic acid (Z)- methyl ester. Mandelup was found to show excellent antioxidant activity. Moreover, Jurien, Gunyidi and Barlock had strong antioxidant activity. Both positive and negative impacts of heat processing were observed on antioxidant activity. Heating and usage of excess water during processing were the key determinants of loss of antioxidants. Negligible loss of antioxidant activity was observed in most of the assays whereas inhibition of both lipid peroxidation (33.53%) and hemolysis of erythrocytes (37.75%) were increased after processing. In addition, in vitro and in vivo antioxidant assays are found to show statistically significant (* p < 0.05 and ** p < 0.01) results, which are supported by the presence of a number of antioxidant compounds in GC-MS analysis.

Abstract:
Background: Microorganisms from understudied habitats have been shown to be an important source of novel bioactive compounds. Endophytes constitute an underexplored group of microorganisms, of which those from aquatic plants have been even less studied. Nelumbo nucifera (lotus) is an aquatic plant with medicinal properties. A screening program for endophytes from N. nucifera by our research group resulted in many microbial isolates, of which isolate L-003 was a promising candidate, exhibiting antimicrobial and antioxidant activities. Objectives: The major objectives were to characterize the endophyte L-003 for its antimicrobial and antioxidant properties, identify the constituent bioactive compounds by GC-MS and characterize their activities further using in silico software. Methods: L-003 was identified by PIBWin software. Antimicrobial activity of the aqueous and organic extracts of culture supernatant of L-003 was checked against a panel of bacteria and fungi. Since the ethyl acetate extract showed the best antimicrobial activity, it was further characterized by thin layer chromatography, an activity confirmed by bioautography and purified by column chromatography. Total antioxidant capacity was assayed by standard techniques. Partially purified metabolite fingerprints were identified by GC-MS analysis. Results: Based on morphological and biochemical analyses, isolate L-003 was identified as belonging to Streptococcus sp. All the organic solvent extracts showed antimicrobial activity. Ethyl acetate extract showed maximum antimicrobial activity against all selected targets and exhibited antioxidant activity too, though butanol and aqueous extracts showed higher antioxidant activity. Two compounds, Acetic acid,-hydroxy, methyl ester and Disulfide, dipropyl, were identified by GC-MS in the metabolite fingerprint. These compounds showed differences in observed and calculated retention indices and could, therefore, be novel. In silico activity, characterization confirmed the antimicrobial and antioxidant properties attributed to these compounds. Conclusion: This is the first study reporting metabolite fingerprinting, identification and characterization of bioactive compounds from an endophytic isolate of Nelumbo nucifera. We conclude that endophytes from aquatic plants could be prospective sources of bioactive compounds, in this case with antimicrobial and antioxidant activities.

Abstract:
In this study, bioactive properties and GC-MS analyses of the Camellia sinensis (seed, leaf, and blossom parts) and commercial black tea extracts were compared. The total phenolic content (TPC) and antioxidant and antimicrobial activities of extracts were determined. The gas Chromatography-Mass Spectrometry (GC-MS) technique was used to identify the major bioactive compounds in extracts. The TPC and antioxidant activity values of the alcohol extract prepared from the leaf part of the C. sinensis are higher than the other extracts. There was a strong correlation between total phenolic content and antioxidant amount among the ethanol extracts of C. sinensis. In antimicrobial evaluation, the ethanol extracts showed more activity; the ethanolic extract of C. sinensis seeds was the most effective. GC-MS results indicated various organic compounds in the C. sinensis extracts, mainly saturated and unsaturated aromatic esters, aromatic alcohols, some cyclic structures, aromatic amine, and boranic esters with different therapeutic activities. The black tea extracts exhibited a more straightforward variety of bio components as aromatic esters and boranic ester. According to the obtained results, C. sinensis and black tea extracts would exert several beneficial effects by their biological activities thanks to the possible synergistic effect of chemical contents detected by GC-MS analysis. However, GC-MS results indicated that the black tea sample had much fewer bioconstituents than fresh C. sinensis plant samples.

Abstract:
Quail egg yolk oil (QEYO) has a rich history of medicinal use, showcasing heightened antioxidant and bioactive properties in our prior studies. This positions QEYO as a promising candidate for therapeutic and cosmetic applications. In this investigation, QEYO was extracted using ethanol/chloroform and 2-propanol/hexane solvents. GC–MS and FTIR analyses quantified 14 major bioactive compounds in the ethanol/chloroform fraction and 12 in the 2-propanol/hexane fraction. Toxicity evaluations in fruit flies, spanning acute, sub chronic, and chronic exposures, revealed no adverse effects. Negative geotaxis assays assessed locomotor activity, while biochemical assays using fly hemolymph gauged antioxidant responses. Real-time PCR revealed the relative expression levels of the antioxidant and anti-inflammatory genes. FTIR spectra indicated diverse functional groups, and the GC–MS results associated bioactive compounds with the regulation of the anti-inflammatory genes EIGER and UPD2. While no significant change in SOD activities was noted, male flies treated with specific QEYO doses exhibited increased catalase activity and total antioxidant capacity, coupled with a significant decrease in their malondialdehyde levels. This study offers valuable insights into the bioactive compounds of QEYO and their potential regulatory roles in gene expression.

The current study investigated the therapeutic potential of Citrullus lanatus seeds which are commonly discarded after eating the fruit. In this day and age, plant secondary metabolites are preferred therapeutic agents to manage a variety of diseases and disorders. The present study aimed to investigate the bioactive secondary metabolite profile of Citrullus lanatus seeds by investigating total phenolic and flavonoid content, antioxidant potential, and Gas Chromatography-Mass Spectrometry (GC-MS) analysis of bioactive compounds and anti-bacterial properties of four different crude extracts. Alkaloids, flavonoids, phenols, steroids, tannins, saponins, phytosterols, terpenoids, and glycosides were revealed in the seeds after qualitative phytochemical examination utilizing several solvents of varying polarity and established techniques of analysis. DPPH radical scavenging assay was used to assess the antioxidant potential and the total flavonoid and phenolic contents in seed extracts were determined using the spectrophotometric method. Methanolic extract revealed higher extractive yield, antioxidant potential, a higher total phenolic content (132.68 ± 0.861 mg of GAg), and higher total flavonoid content (48.13 ± 0.451 mg of Qg) as compared to other extracts. Gas Chromatography-Mass Spectrometry (GC-MS) analysis of all four seed extracts revealed the presence of 27 high and low molecular weight chemical entities in toto with varying amounts. These bioactive chemical substances have been revealed to be physiologically significant and essential from a pharmaceutical standpoint. This research demonstrates that the Citrullus lanatus seeds are high in bioactive secondary metabolites that are beneficial to human health, have a high antioxidant capacity, and antibacterial action against certain bacterial strains, indicating that these seeds have a lot of therapeutic value.

Abstract:
The Eugenia brasiliensis, known as grumixama, is a fruit native to the Brazilian biodiversity and has characteristic flavor and aroma, bioactive compounds with antioxidant properties and benefical health characteristic. Since the consumer market is focused on the demand for products with natural and functional appeal, this study aimed to characterize the grumixama pulp, evaluate the antioxidant potential and trace chemical and volatile organic compounds of this fruit profile. For this purpose, analyzes of titratable acidity, pH, moisture, proteins, ash, fibers, total sugars, and lipids were performed. The determination of total phenolic compounds used the Folin-Ciocalteu method, and the antioxidant activity used the radical ABTS test. The characterization of the chemical profile consisted of obtaining fingerprints using Paper spray PS/MS and the extraction of volatile organic compounds employing solid-phase microextraction (SPME) using PDMS/DVB fiber and subsequent separation and identification by CG-MS. The grumixama pulp stood out for its acidity and high fiber content (20.34g/100g of pulp), in addition to presenting average levels of total phenolic compounds (173.85 ± 3.21 mg 100 g of pulp) and antioxidant activity (844.86 ± 2.03 mM/100g of pulp). Regarding the chemical profile of the pulp, 45 compounds were listed by PS/MS, with emphasis on flavonoids, phenolic compounds, carotenoids, sugars, catechins and quercetin derivatives. Nineteen volatile organic compounds can be identified, all of them belonging to the terpene class, 94.7% sesquiterpenes, and 5.3% monoterpenes, compounds that are responsible for several sensory characteristics of the fruits. The results showed that the association between the antioxidant activity promoted by the bioactive and the VOCs of the grumixama pulp make this fruit promising for acceptance in the market and can be added to various product elaborations, increasing its nutritional and functional value.

Abstract:
Broccoli microgreens, rich in bioactive compounds, offer health benefits aligned with SDG 3: “Good Health and Well-Being.” Their antioxidants combat oxidative stress tied to chronic diseases, but drying can affect their activity. This study assessed the antioxidant capacities of fresh, microwave-dried, and air-fryer-dried broccoli microgreens using in vitro (DPPH assay) and in silico (molecular docking and dynamics) methods. The microgreens were cultivated under controlled conditions and dried using microwave and air-fryer techniques. Antioxidant activity was evaluated using the DPPH assay using ethanolic extracts. The bioactive compounds of fresh microgreens, detected through GC-MS, were analyzed in silico to evaluate their interactions with the target proteins CYP2C9 and NOX2. The findings revealed that air-fryer-dried microgreens demonstrated the highest DPPH activity, followed by fresh microgreens, while microwave-dried samples exhibited the lowest activity. GC-MS analysis of fresh samples revealed the presence of various compounds, including acids, ketones, sulfides, heterocycles, alcohols, esters, aromatic compounds, phthalate ester, and aldehydes. Molecular docking revealed strong interactions of certain compounds in fresh samples and CYP2C9 and NOX2, suggesting therapeutic potential against oxidative stress. Molecular dynamics simulations (MDS) showed stable binding for the CYP2C9-Methyl myristate complex, while the NOX-(Z)-1,2-Diphenylethene complex displayed weaker stability. In conclusion, broccoli microgreens show potential in mitigating oxidative stress, with air-fryer drying slightly enhancing their antioxidant activity. The antioxidant capacity of fresh microgreens is comparable to that of air-fryer-dried microgreens. In silico analyses demonstrate stable interactions between compounds in fresh microgreens and key proteins implicated in oxidative stress.

Abstract:
Avocado (Persea americana) is widely recognized for its high antioxidant capacity. Its rich phytochemical composition is crucial in mitigating oxidative stress and managing chronic conditions such as cardiovascular disease and hyperlipidemia. This study aimed to investigate the phytochemical profile, antioxidant activity, and antihyperlipidemic potential of ethanol extracts derived from avocado seeds. Phytochemical screening and Gas Chromatography-Mass Spectrometry (GC-MS) analysis were conducted to identify key chemical constituents, while antioxidant activity was assessed using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay. In addition, in-silico techniques were employed to evaluate the antihyperlipidemic potential of the bioactive compounds. Phytochemical analysis revealed a variety of bioactive compounds, including volatile compounds, steroids, and fatty acids, contributing to the extract's biological activity. The extract demonstrated strong antioxidant capacity, with an IC50 value of 20.83 ppm, indicating potent free radical scavenging ability. GC-MS analysis identified significant compounds such as Undec-10-ynoic acid, tetradecyl ester, and 9,12,15-Octadecatrienoic acid, 2-(acetyloxy)-1-[(acetyloxy)methyl] ethyl ester, which were further analyzed through molecular docking studies. These studies indicated their potential as inhibitors of hyperlipidemia-associated proteins, with binding energy values exceeding -6 kcal/mol. Moreover, ADMET (Absorption, Distribution, Metabolism, Excretion, and Toxicity) analysis demonstrated favorable pharmacokinetic profiles, including good absorption and low toxicity, positioning these compounds as promising candidates for therapeutic development. The findings of this study underscore the potential of avocado seed extract as a natural source of antioxidants and antihyperlipidemic agents.

Abstract:
The over production of free radicals in the human body is known to cause oxidative stress which plays an important role in the pathogenesis of many diseases. Therefore, the search for natural antioxidants would continue to be a major area of research for many decades. This study was to investigate the in vitro antioxidant activities and to determine the phytochemicals present in Cassia sieberiana. The methanol stem bark extract of C. sieberiana was subjected to phytochemical screening and Gas Chromatography-Mass Spectrometry (GC-MS) analysis. Its antioxidant activities were assayed in vitro using nitric oxide scavenging assay, ferric reducing antioxidant potential assay, lipid peroxidation inhibitory assay and 2-diphenyl-1-picrylhydrazyl scavenging assay. The phytochemical screening of the stem bark extract of C. sieberiana showed saponins, alkaloids, flavonoids, steroids, tannins, phlobatannins, terpernoids, cardiac glycosides, phenolics and reducing sugar. The GC-MS Table revealed that the methanol extract has 51 bioactive compounds with 3-0-Methyl-d-glucose having the highest percentage of 12.16 % while 5.alpha-Androstan-3-beta-ol,4,4-dimethyl- having the lowest percentage of 0.09 %. The antioxidant study showed concentration-dependent radical scavenging activity of the methanol stem bark extract of C. sieberiana. This concentration-dependent result was also observed when compared with ascorbic acid used as the standard drug. The presence of different phytochemicals such as alkaloids, saponins, tannins, phenols, flavonoids, among other things, might be responsible for C. sieberiana antioxidant activity. The study concluded that the methanol stem bark extract of C. sieberiana contains 51 bioactive compounds and showed good antioxidant activity which could be therapeutic in several human diseases.

Abstract:
In recognition of its numerous medicinal benefits, bitter leaf (Vernonia amygdalina L.) is widely used in traditional medicine. Despite substantial research, a comprehensive comparative analysis of the antioxidants and phytochemical properties of its methanolic and aqueous extracts remains undocumented. This study addresses this gap by examining the differences in antioxidant values and phytochemical constituents between the two extracts using advanced analytical techniques. NMR and FTIR spectroscopy were employed to investigate probable phytochemicals, while HPLC and GC-MS determined the differences in biological components. Both DPPH and ABTS radical-scavenging tests evaluated variations in antioxidant activity. NMR Results indicated the presence of aromatic protons, phenolic hydroxyl groups, methyl groups, and methoxylated substances by the singlet signal at 7.1–7.5 ppm, singlet at 4.0–4.5 ppm, doublet at 1.0–1.5 ppm, and singlet at 2.0–2.5 ppm, respectively. FTIR results showed a C=O stretching at 1700 cm-1, an O-H stretching at about 3250 cm-1, and a C=C stretching between 1500 and 1600 cm-1. Methanolic extracts had higher phytochemical values according to GC-MS and HPLC data, except for rutin, delta-cadinene, and alpha-cadinol, which were higher in the aqueous extract. The methanolic extract exhibited superior antioxidant activity in DPPH and ABTS assays, with maximal scavenging activities of 90.5% and 96.8%, respectively. At 200 µg/mL, the aqueous extract demonstrated scavenging activities of 85.4% and 92.7%. These findings underscore the enhanced potential of methanolic extract for therapeutic applications.

Abstract:
The present study aimed to investigate the chemical composition, bioactive compounds, and antioxidant activity of two wild edible mushrooms, the honey fungus (Armillaria mellea) and the parasol mushroom (Macrolepiota procera), collected from Northern Morocco (MA) and Portugal (PT). Those species were chosen due to their edibility, nutraceutical, and medicinal properties. Bioactive compounds (ascorbic acid, tannin, total phenolic, total flavonoid, β-carotene, and lycopene) and their antioxidant activity were determined by spectrophotometric methods. Herein, the fruiting body of the samples revealed a significantly higher amount of bioactive compounds, and values varied between the Moroccan and the Portuguese ones. Methanolic extracts shown a strong antioxidant capacity: Using DPPH free radical-scavenging activity radicals (IC50 1.06–1.32 mg/mL); inhibition of β-carotene bleaching radicals (IC50 0.09–0.53 mg/mL); and, reducing power radicals (IC50 0.52–1.11 mg/mL). The mushroom species with the highest antioxidant capacity was A. mellea from MA. Chemical composition was analyzed by GC-MS and LC-MS methodologies. GC-MS analysis showed that the most abundant biomolecules group was sugar compositions in the four samples (62.90%, 48.93%, 59.00%, and 53.71%) and the main components were galactitol 16.74%, petroselinic acid 19.83%, d-galactose 38.43%, and glycerol 24.43% in A. mellea (MA), A. mellea (PT), M. procera (MA), and M. procera (PT), respectively. LC-MS analysis of individual phenolic compounds revealed that vanillic acid (198.40 ± 2.82 µg/g dry weight (dw) and cinnamic acid (155.20 ± 0.97 µg/g dw) were the main compounds detected in A. mellea, while protocatechuic acid (92.52 ± 0.45 and 125.50 ± 0.89 µg/g dw) was predominated in M. procera for MA and PT samples, respectively. In general, the results of this comparative study demonstrate that the geographic and climatic conditions of the collection site can influence biomolecule compounds and antioxidant properties of wild mushrooms. This study contributes to the elaboration of nutritional, nutraceutical, and pharmaceutical databases of the worldwide consumed mushrooms.

Abstract:
Background: Clerodendrum paniculatum has ethnomedicinal importance in treatment of disorders like wound, typhoid, jaundice, malaria and anemia. Objective: To evaluate the antioxidant and hepatoprotective activity of Clerodendrum paniculatum leaves against carbon tetrachloride (CCl4) induced rat model and identification of its bioactive constituents by Gas Chromatography Mass Spectroscopy (GC MS). Methods: Successive solvent extraction was carried out. Total phenolic, flavonoid content and antioxidant activity by 2,2- diphenyl-1-picryl hydrazyl (DPPH), nitric oxide and 2-Azino-bis [3-ethyl benzothiazoline- 6-sufonic acid] (ABTS method) were done. Ethyl acetate extract was selected for hepatoprotective study in carbon tetrachloride intoxicated model followed by the measurement of liver function marker enzymes such as SGOT (Serum Glutamate Oxaloacetate Transaminase), SGPT (Serum Glutamate Pyruvate Transaminase), and ALP (Alkaline Phosphatase). Biochemical parameters like bilirubin and protein were measured. Histopathologic liver sections were carried out. Bioactive constituents were evaluated by GC MS. Results: By DPPH and ABTS method, ethyl acetate extract showed IC50 as 70.14±0.92 μg/ml,2958.24±2.460 μg/ml, respectively. The alcoholic extract showed maximum IC50 (197.22 ±7.16 μg/ml) by Nitric oxide radical scavenging method. Hepatoprotective study reveals that intoxicated animal groups have elevated levels of enzymes and bilirubin and suppress the production of protein. The extract pre-treatment showed a significant decrease in enzymes and increased production of total protein in a dose-dependent manner. Histopathologic studies also support the hepatoprotective activity. GC MS analysis revealed the presence of seven major bioactive constituents with ethyl palmitate as the major one. Conclusion: The results support the proof for the hepatoprotective potential of the CPLE extract with potent antioxidant activity and enhanced liver enzyme level. The observed activity could be due to the presence of bioactive compounds as identified by GC MS analysis.

Abstract:
Dendrobium amoenum is an epiphytic orchid used as tonic because it has many derivatives of phenols. The crude extract of this orchid has been shown to have antioxidant activity. The objectives of this research are to explore the cytotoxic activity of antioxidant-rich crude extract against the human cervical carcinoma and glioblastoma cell lines by MTT assay and to detect the compounds by GC-MS. Methanol (DAM) extract of D. amoenum showed high cell growth inhibition percentage against the tested cell lines. DAM extract showed high cytotoxic activity against HeLa cells (IC50 – 110.22 μg/ml) and least activity against U-251 cells (IC50 – 550.55 μg/ml). Thirteen compounds were detected and identified in the extract. Based on abundance, four major compounds detected were: (E)-13-docosenoic acid; oleic acid; 11-octadecenoic acid, methyl ester; and hexadecanoic acid, 2,3-dihydroxypropyl ester. The cytotoxic activity of DAM extract is probably due to the presence of these bioactive compounds, confirmation of which needs further investigation.

Abstract:
This study aimed to evaluate the phytochemical composition, mineral content, and antioxidant potential of the hydroethanolic extract of Chenopodium album (CAHE). The mineral content was analyzed using atomic absorption spectroscopy (AAS) with samples prepared by acid digestion. Phytochemical profiling was conducted using Gas Chromatography and Mass Spectrometry (GC-MS), employing a Supelco capillary column and helium as the carrier gas (1.21 mL/min). Mass spectra (m/z 40–600) were analyzed by matching with the NIST library. Bioactive compounds were identified based on the relative peak area and spectral comparisons. Antioxidant activity was evaluated through nitric oxide scavenging, DPPH radical scavenging, reducing power, and metal chelation assays, using ascorbic acid and butylated hydroxytoluene (BHT) as standards. AAS analysis revealed high concentrations of calcium, magnesium, iron, zinc, phosphorus, sodium, and potassium, indicating the nutritional value of CAHE. GC-MS fingerprinting identified bioactive compounds such as linoleic acid ethyl ester, quercetin, and phytol, known for their antioxidant, immunomodulatory, and anti-inflammatory properties. Furthermore, antioxidant assays demonstrated strong free radical scavenging activity. CAHE exhibited significant nitric oxide and DPPH radical scavenging activities compared to ascorbic acid and BHT, respectively, along with moderate metal chelating activity. These results highlight the potential of CAHE in combating diseases related to oxidative stress. The study confirms that C. album contains essential minerals and bioactive phytochemicals with potent antioxidant properties. Its capacity for free radical neutralization underscores its applicability in therapeutic and preventive healthcare products.

Abstract:
Ornamental plants, beyond their aesthetic appeal, possess notable therapeutic and medicinal properties. Asparagus setaceus, commonly cultivated in tropical and subtropical regions, is known for its bioactive compounds, including phenols, tannins, saponins, and flavonoids. This study aimed to investigate the phytochemical composition, antioxidant activity, antimicrobial efficacy, and bioactive compound profiling of A. setaceus leaf extract. Soxhlet extraction with methanol was used in the analysis; the total polyphenol and flavonoid content were estimated to be 121 mg GAE/g and 0.16 mg QE/g, respectively. Dose-dependent antioxidant activity was obtained in the DPPH radical scavenging assay. Through agar diffusion, an inhibition zone of 20 mm as compared to standard antibiotic control was shown, revealing significant inhibition of the Escherichia coli bacterium in antimicrobial activity assayed. GC-MS analysis revealed the presence of 168 bioactive compounds, among which dimethyl ether and hexadecanoic acid were the most abundant, and therefore, have potential therapeutic use, especially in antimicrobial and antioxidant activities. The present findings support the pharmacological importance of A. setaceus as a source of bioactive constituents, which merits further research for therapeutic purposes.

Abstract:
The aim of this research was to explore the chemical composition and antioxidant activities of etheric extracts of Abies marocana. A Soxhlet apparatus was used to extract bioactive molecules from the various parts of the plant. Furthermore, the levels of antioxidant compounds were quantified, while the Gas chromatography was utilized to determine the chemical constituents of the extracted molecules. The extracts were evaluated for their antioxidant properties using the DPPH radical scavenging method and the total antioxidant capacity test. The levels of polyphenols varied across different parts of the plant, ranging from 2.474 ± 0.029 mg.g-1 DM in needles to 4.207 ± 0.008 mg.g-1 DM in twigs. Flavonoids were most abundant in needles 0.140 ± 0.001 mg.g-1 DM and least abundant in cones 0.069 ± 0.007 mg.g-1 DM. Tannins had the highest concentration in twigs 2.608 ± 0.114 mg.g-1 DM, followed by cones 1.948 ± 0.037 mg.g-1 DM and needles 1.512 ± 0.09 mg.g-1 DM. A chromatographic analysis revealed that 56 components were in the samples, with terpene compounds being the most abundant in the different organs. In terms of antioxidant activity, the extract derived from twigs exhibited the strongest antioxidant capacity 49.377 ± 0.371 mg EAA.g-1 DM, followed by cones 35.129 ± 0.084 mg EAA.g-1 DM and needles 13.663 ± 0.084 mg EAA.g-1 DM. Alternatively, the IC50 values for the three organs were found to be in the range of 3844 to 5047.67 µg.mL-1. The results highlight the potential phytopharmaceutical value of A. marocana due to the presence of diverse phyto-components.
