In the study 5α- 6α- epoxyergosta 7-en- 3β- ol was isolated from Microcosmus vulgaris. Furthermore, antioxidant and antiproliferative activity of crude extract and 5α- 6α- epoxyergosta 7-en- 3β- ol were determined by DPPH, superoxide radical scavenging and nitric oxide radical scavenging and MTT assay respectively. Antimicrobial activity of crude extract was also determined against some Gram positive, Gram negative and yeast strains. Stearic acid, palmitic acid and myristic acid were also detected by GCMASS analysis. This is the first study about isolation and bioactivity determination of Turkish M. vulgaris.
