摘要
From the marine sponge Jaspis sp., a new isomalabaricane triterpenoid 22, 23- dihydrostellettin D (1) was isolated, and its structure was established on the basis of IR, MS and extensive 2D NMR spectroscopic analysis. It is a unique skeleton compound rarely obtained from Chinese marine organisms.
