Two new pregnanes from Aglaia perviridis Hiern

Abstract

Two new pregnanes, 2α,3α,20-trihydroxy-16β-acetoxy-20(R)-pregnane (1) and 2α,3α,15β-trihydroxy-16β-acetoxy-pregnane-20(R)-methacrylate (2), along with five known compounds, were isolated from the ethanolic extract of the twigs of Aglaia perviridis Hiern using chromatographic methods. The structures of 1 and 2 were elucidated on the basis of spectral data.
