New hopane triterpene from Dicranostigma leptopodum (Maxim) Fedde.

Phytochemical investigation of the whole plant of Dicranostigma leptopodum (Maxim) Fedde led to the isolation of a new hopane triterpene, dicranostigmone (1), and a known compound, erythrodiol-3-O-palmitate (2). The structure of the new compound (1) was elucidated by various spectroscopic methods including 2D NMR techniques (gCOSY, HMQC, HMBC, NOESY), HR-ESI-MS, and X-ray.
