Study of Isolation, Characterisation and Antimicrobial Activity of High Value Bioactive Compounds from Methanolic Extract of Leaves of Tilkor (Momordica monadelpha)

In this paper an attempt has been made to highlight the physicochemical study of methnolic extract of leaves of Tilkor carried out by soxhlet extraction process, phytochemical analysis of the extract, separations, isolation of bioactive components through Thin Layer Chromatography (TLC) as well as column chromatography respectively and characterisation of isolated compound by the means of several spectral analysis such as H-1 NMR, C-13 NMR, IR, U.V. Mass spectroscopy. The methanolic extract of leaves of the plant (in tropical conditions of Mithilanchal, Bihar, India) reveal the presence of phytochemicals like alkaloids, flavanoids, tannins, saponins, cardiac glycosides, steroids, terpenoids etc. The secondary metaboilities showed antimicrobial activity. The two isolated compounds were characterised by spectroscopic techniques which revealed the structure of compound A as - stigmosterol and compound B as tritriaconatane and is also found to have antimicrobial activity.
