Current study was intended to isolate bioactive compounds from ethyl acetate fraction of Saussurea hypoleuca root extract and evaluation of their antioxidant, antimicrobial and anti-cancerous activities which might be helpful for their chemo preventive potential against selected bacterial strains. Column chromatography was done for isolation of compounds which were characterized on the basis of extensive spectroscopic analysis; Infra-red (IR), Electron Ionization (EI-Positive), Proton Nuclear Magnetic Resonance (1H-NMR) and Carbon Nuclear Magnetic Resonance (13C-NMR). Two compounds were identified, as sesquiterpenes (40mg) and linoleic acid (33mg) from 10 grams of ethyl acetate fraction. Both compounds have shown in vitro antioxidant activity which in regard; 2, 2- diphenyl-1-picrylhydrazyl (DPPH) scavenging potential was high in sesquiterpenes (261.81) as compared to linoleic acid (90.89). The minimum inhibitory concentrations (MIC) of both compounds were evaluated in various bacterial and fungal strains against respective controls. However, in human hepatocellular carcinoma (Hep G2 cell lines) sesquiterpenes exhibited strong anticancer potential than linolenic acid which might be its potential free radical inactivator in MTT assay. This paper directs the ethano medicinal worth of plant root as it possesses bioactive compounds which in our best knowledge these compounds isolated and reported first time from this plant root specie.
