摘要
A phytochemical investigation of the flowers and bulbs of Allium triquetrum has been undertaken, leading to the isolation of five new furostanol saponins, triquetrosides A1/A2 (1a/1b), B (3), and C1/C2 (4a/4b), from the flowers, along with ascalonisides A1/A2 (6a/6b). The 22-O-methyl derivatives of triquetrosides A1/A2 (2a and 2b) and C1/C2 (5a and 5b) were also isolated, but they are considered extraction artifacts. Large amounts of seven kaempferol glycosides, of which one (7) has a new structure, were also isolated from both flowers and bulbs. The structures of the new compounds were determined by spectral and chemical methods.
