Phytochemical screening and GC-MS analysis of Cyperus dubius, Rottb. (Cyperaceae)

Abstract

In the present study the investigation on phytochemical screening was carried along with GC-MS analysis to identify the phyto-constituents present in extracts of Cyperus dubius, Rottb. Phytochemical analysis in different extracts (methanol, hexane) revealed the presence of secondary metabolites like alkaloids, flavonoids, phenols, terpenoids, glycosides, Phytoserols, quinone. Whereas, the GC-MS analysis showed 30 peaks indicates the presence of 30 compounds and among these Stigmast-5-en-3-ol, (3.beta.)-[31.39%] was found to be major compound followed by Stigmasterol (9.40%), Guanosine (6.44%), Ergost-5-en-3-ol, (3.beta.)-(6.39%), Olivetol, dimethyl ether (5.75%), 1,3,4,5-tetrahydroxy-cyclohexanecarboxylic acid (4.39%), 2-methyl-2-[2-(2,6,6-trimethyl-3-methylene-cyclohex-1-enyl)-vinyl]-[1,3]dioxolane (4.14%), 9-octadecenoic acid (Z)-(3.96%), Methyl commate C (3.91%), 2,5-dimethoxybenzylamine (3.73%), 4-formyl-2-methoxyphenyl acetate (3.47%) and Gamma.-tocopherol (2.99%) which possess pharmacologically and industrially potential phyto compounds like antioxidants, phytosteroids and number of unsaturated fatty acids.
