摘要：
Fractionation of the methanol extract of Gnaphalium gaudichaudianum DC afforded one new and six known ent-pimarane diterpenes together with velutin, squalene and stigmasterol. The structure of the new compound was established on the basis of extensive I D and 2D NMR spectroscopic data interpretation. Two of the isolated compounds exhibited moderate toxicity in the Artemia salina toxicity test. (C) 2002 Elsevier Science Ltd. All rights reserved.
