Abstract:
The present study was aimed at analysis of bioactive constituent of whole plant of Cyathula prostrata. The methanol extracts of the plant was subjected to Fourier transform infrared spectroscopy (FT-IR) and Gas Chromatography-Mass Spectroscopy (GC-MS) analysis. GC-MS analysis of the plant extract was performed using Perkin-Elmer GC clarus 500 system and interpretation on mass spectrum GC-MS was conducted using the database of National Institute Standard Technology (NIST). The IR spectrum was recorded in the spectrophotometer (Thermo Scientific NICOL-ISS). The GC-MS analysis reveals a total of twenty-four compounds, such as Benzene (1-methyl decyl). Tetracosanoic acid methyl ester, Dibenzo[b,f][1,4] diazone, Docosanoic acid methyl ester, formic acid -3, 7, 11- tri methyl -1, 6, 10-dodecatriene-3-yl ester, cis-vaccinic acid, 1-phenol-3,4-dihydroisoquinoline. 9-octadecanoic acid (2) methyl ester and Heptacocosanoic acid methyl ester. FT-IR analysis of methanol extract was carried-out and the compounds indicated shows absorption peaks at 3392cm^-1(OH)­_­, 2892cm^-1 (C-H), 1731cm^-1 (C=O) 1680cm^-1 (C=C) and 1039cm^-1 (C-O). From the study, it can be concluded that phytochemicals were observed in methanol extract of Cyathula prostrata. Which reveals that the plant is highly valuable in medicinal usage for the treatment of various human ailment.
