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.
