Steroids and alkaloids from the South China Sea sponge Axinella sp

J Asian Nat Prod Res. 2009 Dec;11(12):1040-4. doi: 10.1080/10286020903367136.

Abstract

A new steroid 24beta-methylcholasta-1,8,14,22,25-penten-3-one-5alpha-ol (1) and a new alkaloid 1-(1H-indol-3-yl)-2,3-dihydroxy-5-methyl-hexane (2), together with four known compounds, were isolated from the EtOH extract of the South China Sea sponge Axinella sp. The structures of 1 and 2 were determined on the basis of extensive spectroscopic analysis, including 1D and 2D NMR spectral data.
