Abstract
Reptansterone ( 8), a new C-29 phytoecdysteroid with a δ-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 from the corresponding 1H and 13C-NMR homo- and heterocorrelations and IR and HPLC-MS(TSP) spectral data.
