摘要：

From the ethanol extract of the roots Euphorbia ebracteolata, two new casbane diterpenoids, named yuexiandajisu A and B, were isolated. Their structures were elucidated by spectral analyses including H-1-H-1 COSY, C-13-H-1 COSY, COLOC and NOESY and confirmed by X-ray crystallography. In vitro bioassays showed that yuexiandajisu A exhibited antibacterial activity and yuexiandajisu B inhibited proliferation of B lymphocytes. (C) 1998 Elsevier Science Ltd. All rights reserved.
