摘要：

Reptansterone (8), anew C-29 phytoecdysteroid with a delta-lactone in the side chain, was isolated from roots of a green variety of Ajuga reptans. Likewise, other unprecedented members of this polyhydroxysteroid family namely 28-epi-sengosterone (9), 5,29-dihydroxycapitasterone (10) 2- and 3-dehydroajugalactone (11 and 12) were isolated from A. reptans var. atropurpurea. The structures of all these new compounds were inferred fi-om the corresponding H-1 and C-13-NMR homo- and heterocorrelations and IR and HPLC-MS(TSP) spectral data Copyright (C) 1996 Elsevier Science Ltd
