- Available online from an cytotoxic endophytic fungus Botryotinia fuckeliana A-S-3, three cytochalasans phenochalasin B (4), -cytochalasin (5) and one [1,3] dioxacyclotridecino (6), along with two new ent-eudesmane sesquiterpenes, 1-keto-4α,15-epoxyeudesm-11-ol (1), and ent-4(15)-eudesmen-5,6-ol-1-one (2), and one known ent-eudesmane sesquiterpene ent-4(15)-eudesmen-11-ol-1-one (3) were isolated. The structures of these compounds were elucidated by interpretation of spectroscopic data. Among these compounds, two cytotoxic constituents were identified.
