摘要：

The sterol composition of two Teucrium species (abutiloides and betonicum) was studied. Both plants were shown to contain three 24-ethylcholestane derivatives, all of them having the 24 beta-configuration. These were identified as (24S)-24-ethylcholesta-5,22(E),25-trien-3 beta-ol, (24S)-24-ethylcholesta-5,25-dien-3 beta-ol (clerosterol) and (24R)-24-ethylcholesta-5,22(E)-dien-3 beta-ol (poriferasterol) by spectroscopic analysis of their acetates and by comparison of their physical data (mp, [alpha](D)) with those reported in the literature for these compounds. Some disagreements in the previously published data of these sterols are clarified and chemotaxonomic aspects are briefly discussed. Copyright (C) 1996 Published by Elsevier Science Ltd
