摘要
Four new flavonoid glycosides, curcucomosides A-D (1-4), three known flavonoid glycosides, 5-7, and four known diarylheptanoids, 8-11, were isolated from the ethanol extract of the aerial parts of Curcuma comosa. The structures of the new compounds were established as rhamnazin 3-O--l-arabinopyranoside (1), rhamnocitrin 3-O--l-arabinopyranoside (2), rhamnazin 3-O--l-rhamnopyranosyl-(1鈫?)-O--l-arabinopyranoside (3), and rhamnocitrin 3-O--l-rhamnopyranosyl-(1鈫?)-O--l-arabinopyranoside (4) by spectroscopic analysis and chemical reactions whereas those of the known compounds were identified by spectral comparison with those of the reported values.
