Abstract
Two new pregnene derivatives 14β-15α-dihydroxy-Δ4pregnene-3,20 dione and 3β-14β, 15α-16α hydroxy-20-oxo- Δ5pregnene-tetra-ol, in addition to α- and β-amyrin and β-sitosterol, were isolated from Solenostemma argel leaves. The structures were established by extensive spectral analysis as well as comparison with reference materials. © 2001 Elsevier Science Ltd.
