Hepatoprotective triterpenes from Sedum sarmentosum

The known delta-amyrone, 3-epi-delta-amyrin, delta-amyrin as well as anew hydroperoxy triterpene, 18 beta-hydroperoxy-olean-12-en-3-one (named sarmentolin) were isolated as hepatoprotective agents from Sedum sarmentosum. Their structures were elucidated by spectral analysis and chemical reactions. (C) 1998 Elsevier Science Ltd. All rights reserved.
