Objective: Verification of the herbal plants by latest scientific tools toward understanding the molecular mechanism underlying their medicinal role is the need of the hour. Methods: Gas chromatography-mass spectrometry study of water extracts of the leaves of one herbal plant, Aristolochia indica was undertaken by standard procedures and its medicinal activity was verified with the biomolecules present in it. Results: The presence of some important biomolecules such as 2-propenoic acid, ethenyl ester, oxalic acid, cyclobutyl ethyl ester, phosphoric acid, 2-chloroethenyl dimethyl ester, pentanoic acid, 2-methylcyclohexyl ester, cis-, butylphosphonic acid, butyl cyclohexylmethyl ester, octadecanoic acid, 2,3-dihydroxypropyl ester, acetic acid, cesium salt and 2-Fluoro-6-trifluoromethylbenzoic acid, 4-nitrophenyl ester, and some others indicate represents the medicinal roles of this plant as is reported ethnopharmacologically. Conclusions: The results and discussion above clearly indicate that the various molecules present in A. indica leaf extracts do have medicinal roles ascribed to it and further work in this regard is on.

Objective: The scientific validation of ethnopharmacologically important herbal plants by latest techniques is necessary to understand their medicinal efficacy. Methods: Gas chromatography-mass spectrometry study of one herbal plant, Dodonaea viscosa var. angustifolia was undertaken by standard procedures and its medicinal activity was verified with the biomolecules present in it. Results: The presence of some important biomolecules such as catechol, N-benzyl-2-phenethylamine, acetic acid, 4-oxocyclohexyl ester, 4-amino-3-mercapto-1,2,4-triazole, 1,1'-methylene-bis(di-2-propenylamine), inositol, alanine, N-methyl-N-methoxycarbonyl-, hexyl ester, 1,3-dioxolane, 2-methyl-2-pentyl-, cyclohexane, 1-methyl-3-(1-methylethenyl)-, cis-, phthalic acid, di(2,3-dimethylphenyl) ester, heptafluorobutyric acid, 2-naphthyl ester, and 2-fluoro-6- trifluoromethylbenzoic acid, 4-nitrophenyl ester has biochemical properties which represent the ethnomedicinal roles of this plant. Conclusions: The presence of these biomolecules having medicinal properties supports the validity of the medicinal roles of D. viscosa var. angustifolia. [ABSTRACT FROM AUTHOR]

Objective: Scientific efficacy evaluation of herbal plants for their medicinal roles is needed to establish their importance in medical science. The present study deals with the gas chromatography-mass spectrometry (GC-MS) analysis of one medicinal plant, Stachytarpheta indica. Methods: The GC-MS study of water extracts of the leaves of one herbal plant, S. indica was undertaken by standard procedures and its medicinal activity was verified with the biomolecules present in it. Results: The presence of some important biomolecules such as sulfurous acid, 2-ethylhexyl hexyl ester, and pentanoic acid has medicinal roles such as acidifier, arachidonic acid inhibitor, and increase aromatic amino acid decarboxylase activity. N-t-Butylpyrrole, 1-hexanol, 4-methyl-, 3-methyl-2-(2-oxopropyl)furan, butanoic acid, 3-methyl-, 3,7-dimethyl-6-octenyl ester, hexadecanoic acid, methyl ester, 11,14,17-eicosatrienoic acid, methyl ester, 2-methylheptanoic acid and 2-propenoic acid, 3-(dimethylamino)-, methyl ester, etc., have very important medicinal roles which correlate well with the medicinal role of the plant. Conclusions: The results and discussion above clearly indicate that the various molecules present in S. indica leaf extracts do have medicinal roles ascribed to it and further work in this regard is on.

Objective: The present study deals with the preliminary phytochemical and gas chromatography-mass spectrometry (GC-MS) analysis of different leaf extracts of one medicinal Carissa carandas. Materials and Methods: The phytochemical and GC- MS study of one medicinal plant, C. carandas was done as per standard protocols to correlate its medicinal activity with the biomolecules present in it. Results: The methanol extract of C. carandas indicated the presence of flavonoids, tannins, saponins, and steroids, whereas flavonoids, alkaloids, saponins, and steroids were present in hexane fraction. Alkaloids, saponins, proteins, and triterpenoids were present in aqueous extract. The GC-MS analysis of hexane and aqueous leaf extracts indicated the presence of some important biomolecules such as pentadecanoic acid, 14-methyl-, methyl ester, 9,12,15-octadecatrienoic acid, (Z, Z, Z)-, Phytol, Bis(2-ethylhexyl) phthalate, Squalene, Octasiloxane, 1,1,3,3,5,5,7,7,9,9,11,11,13,13,15,15- hexadecamethyl, beta.-Sitosterol, 9,12,15-Octadecatrienoic acid, 2-[(trimethylsilyl)oxy]-1-[[(trimethylsilyl)oxy]methyl] ethyl ester, (Z, Z, Z)-Acetamide, N-methyl-N-[4-(3-hydroxypyrrolidinyl)-2-butynyl]-, 5,8,11,14-Eicosatetraenoic acid, methyl ester, (all-Z)-, and 6-Octadecenoic acid, methyl ester, (Z). Conclusions: The presence of these molecules augurs well with the medicinal properties attributed to this plant ethnobotanical. Further work is in progress toward understanding this plant's role as a medicine. [ABSTRACT FROM AUTHOR]
