New pregnane steroids from Turraea pubescens

Three new pregnane steroids, 2β,3β,5β-trihydroxy-pregn-20-en-6-one (1), 3β-hydroxy-5α-pregn-7,20-dien-6-one (2), and 3β-acetoxy-5α-pregn-7,20-dien-6-one (3) were isolated from the twigs and leaves of Turraea pubescens, and were structurally elucidated on the basis of spectroscopic data and chemical method.
