Abstract:
To study the chemical constituents from the stems of Cipadessa cinerascens. The constituents were separated by column chromatography and their structures were elucidated by spectral data analyses. Seventeen chemical constituents were isolated from the EtOAc extract in the stems of C. cinerascens and their structures were identified as lanost-7-en-3-one-22, 25-epoxy-23, 24-acetone acetal (1), chisopanin M (2), 3β-hydroxy-5-en-stigmast (3), 7α-hydroxy-4-en-3-one-stigmast (4), 3β-hydroxy-5-en-7-one-stigmast (5), 7α-hydroxysitosterol (6), 22E-7α-methoxy-5α, 6α-epoxy-8 (14), 22-dien-3β-hydroxy-ergosta (7), 7β-hydroxy-4-en-3-one-cholest (8), 3β-acetyloxy-2β, 4β-dihydroxy-16-one-pregnan (9), 17α, 20R-dihydroxy-3, 16-dione-pregnan (10), 2β, 3β-dihydroxy-16-one-pregnan (11), 3β, 7α-dihydroxy-20-one-pregnan (12), 2α, 3β-dihydroxy-5-en-20-one-pregnan (13), 1, 4-dien-3, 16-dione-2-hydroxyandrosta (14), 5-en-17-one-3β, 16β-dihydroxyandrost (15), apegenin (16), and annuionone D (17). Conclusion All the compounds except 14 and 17 are obtained from this plant for the first time.
