摘要：

Hexane extract of fresh rhizomes of Pyrroisa lingua (Thunb.) Farwell. yielded five new dammarane triterpenoids, designated as octanordammarane (1), (18S)-18-hydroxydammar-21-ene (3), (18S)-pyrrosialactone (5), (18S)-pyrrosialactol (7) and 3-deoxyocotillol (8), along with known dammara-18(28),21-diene (2). Structures of 1, 3, 5, 7 and 8 were elucidated by mainly 2D NMR and other spectroscopic analyses and chemical correlations. (C) 1998 Elsevier Science Ltd. All rights reserved.
