摘要：
Three new metabolites including two new steroids, chabrolosteroids A and B (1 and 2), and a novel spirosteroid chabrolosteroid C (3), were isolated from the organic extract of a Taiwanese soft coral Nephthea chabrolii. The structures of these metabolites were elucidated by extensive spectroscopic analysis and by comparison of the spectral data with those of related steroids. This is the first report of a steroid with a spiro-ring A, B system in natural products. (c) 2006 Elsevier Ltd. All rights reserved.
