10.22376/ijpbs.2019.10.1.p1-12 Volume 5 Issue 4 2014 (October - December) The aim of the study was to investigate the phytoconstituents present in petroleum ether and methanolic extract of lessThan i greaterThan Solanum virginianum lessThan /i greaterThan L leaves by Gas Chromatography & Mass Spectroscopic method. In the GC-MS analysis, five phytochemical components were identified in the petroleum ether extract and seven phytochemical components were identified in the methanolic extract of lessThan i greaterThan Solanum virginianum lessThan /i greaterThan L. GC-MS analysis of lessThan i greaterThan Solanum virginianum lessThan /i greaterThan L petroleum ether extract revealed the existence of the major compounds such as Aspidospermidin-17-ol,1-acetyl-19,21-epoxy-15,16-dimethoxy (Retention time11.58), L-(+)-Ascorbic acid 2, 6-dihexadecanoate (Retention time15.38), Estra-1,3,5 (10)-trien-17-ol (Retention time18.77) and the chemical constituents were identified in methanolic extract are N,N'Dibenzylidene-3,3'-dichlorobenzidine (Retention time 9.42),16-Allopregnen,3a,7a,11a-triol-20-one, triacetate (Retention time14.27). This type of GC-MS analysis is the first step towards understanding the nature of active principles in this plant. S. SUNDAR AND Y.
