Abstract

Abstract:

Seven pregnane steroids were isolated from the petroleum ether extracts of a South China Sea gorgonian Menella sp. collected in the Sanya Bay. By means of spectroscopic analysis and comparison with literatures, their structures were identi-fied as 3α-hydroxy-5β-pregnan-20-one (1), 3β-hydroxy-5α-pregnan-20-one (2), 3β-hydroxy-pregnan-5-en-20-one (3), 5β-pregnan-3, 20-dione (4), 5α-pregnan-3, 20-dione (5), pregnan-4-en-3, 20-dione (6), and pregnan-1, 4-dien-3, 20-dione (7), respectively. All compounds except compound 2 were isolated from this genus for the first time, and the NMR data of com-pound 7 was reported for the first time.

Key words: Menella sp., pregnane steroids, chemical constituents, structure identification
