Sesquiterpenes produced by HF 12440 isolated from .

A drimane-type sesquiterpene, (+)-dendocarbin L () together with two bisabolane-type sesquiterpenes, (+)-sydonic acid () and (+)-sydowic acid () were isolated from the mycelium of HF 12440, an endophytic fungus from the stem of . The structures of all compounds were elucidated using spectroscopic methods and by comparison with the literature. Compound was isolated from the fungi for the first time, compounds and were firstly obtained from this endophytic fungus. Compound showed cytotoxicity (IC 2.56 μg/mL) against murine leukemia P-388 cells.
