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.
