Megastimanes and ergostane type steroid from leaves Cratylia mollis (Leguminosae)

from the methanolic extract of the leaves of cratylia mollis were obtained by chromatographic techniques (3s,5s,6s,9r)-3,6-dihydroxy-5,6-dihydro- β-ionol (1), and a new bis-norisoprenoid named (4s*, 6s*)-4-but-1e-enyl-4,6-dihydroxy-3,5,5-trimethyl-cyclohex-2-enone (2) as well as 5a,8a-epidioxyergosta-6,22-dien-3-β-ol. the structures of the pure compounds were elucidated based on ms, 1h and 13c nmr spectroscopic data analyses.
