| 摘要 | The present study was carried out to enlist herbicidal and antimicrobial compounds in the methanolic stem extract of Carthamus oxycantha, a problematic weed of Asteraceae. Methanolic stem extract was subjected to GCMS analysis that revealed the presence of 150 constituents in the extract. The most abundant compound was Niacin (45.375%) followed by D-ribofuranose, 5-deoxy-5-(methylsulfinyl)-1,2,3-tris-O-(trimethylsilyl)- (14.528%); 9,12-octadecadienoic acid (Z,Z)-, methyl ester (4.951%); γ-tocopherol (4.638%); hexacosane (4.148%); 3-phenyllactic acid, 2TMS derivative (2.675%); 13-retinoic acid, (Z)-, TMS derivative (2.461%); 2,2,5,5-tetramethyl-4-ethyl-3-imidazoline-1-oxyl (2.276%); octadecanoic acid (1.851%); 2-deoxy-1,3,4,5-tetrakis-O-(trimethylsilyl); pentitol (1.757%); 3,5,5-trimethyl-4-(3-((trimethylsilyl)oxy)butyl)cyclohex-2-enone (1.505%); methyl 9.cis.,11.trans.t,13.trans.-octadecatrienoate (1.136%); and benzoic acid, 3-[(trimethylsilyl)oxy]-, trimethylsilyl ester (1.044%). Peak areas for the rest of the compounds were below 1%. Among the identified compounds, 9,12-octadecadienoic acid (Z,Z)-, methyl ester (3), hexacosane (5), 9,12-octadecadienoic acid (Z,Z)- (28), tetradecanoic acid, methyl ester (29), hexadecanoic acid, methyl ester (30), γ-sitosterol (33), 9,12,15-octadecatrienoic acid, (Z,Z,Z)- (48), dodecanoic acid (68) and eicosane (128) are known to possess antimicrobial activities. Compound 28 is also known for its herbicidal activity as a binary mixture with xanthoxyline. This study concludes that the stem extract of C. oxycantha primarily comprises antifungal and antibacterial compounds. |
