Abstract
A novel furanosteroid named 9-epi-viridiol (1), along with viridiol (2) and mevalonic acid (3), was isolated from Trichoderma virens. The structure of 1 was verified by combined spectroscopic data (COSY, HSQC, HMBC and NOESY) to be a C-9 epimer of viridiol. 9-epi-Viridiol exhibited cytotoxicity towards HeLa and KB cells with IC50 values of 19 and 50 microg mL(-1), respectively.
