摘要：

Two new l4α -methylsterols, roxburghiadiol A and roxburghiadiol B, were isolated from the leaves and fruits of Aglaia roxburghiana. Previously their structures were tentatively assigned as 4-bisnormethyl-24-methylenecycloarta-3β,7α-diol and 4-bisnormethyl-24-methylenecycloarta-3β,6α-diol, respectively. A reinvestigation using 2D-nmr technique has confirmed the structure 2 for roxburghiadiol B as previously reported, and roxburghiadiol A is now found to be the corresponding 6β epimer 1. © 1990, American Chemical Society.
