Chemical Constituents from Roots of Canna generalis

Abstract:

In order to understand the chemical constituents of Canna generalis, eight compounds were obtained from its roots. On the basis of spectral data, their structures were identified as dehydrovomifoliol (1), 3,4-dihydroxybenzoic acid ethyl ester (2), caffeic acid ethyl ester (3), stigmast-4,22-dien-3,6-dione (4), stigmast-4-ene-3,6-dione (5), stigmastane-3,6-dione (6), β-sitosterol (7) and stigmasterol (8). All the compounds were reported from Canna generalis for the first time.
