Non-isoprenoid botryane sesquiterpenoids from basidiomycete Boletus edulis and their cytotoxic activity

摘要

Three non-isoprenoid botryane sesquiterpenoids,named boledulins A-C(1-3),have been isolated from the cultures of basidiomycete Boletus edulis Bull.The structures were established by means of spectroscopic methods.Boledulin A(1)exhibited moderate inhibitory activity against five human cancer cell lines.
