Objective: To investigate chemical constituents from flowers of Pueraria lobata. Method: Flowers of P. lobata was carried out with silica column chromatography
Sephadex LH-20 and preparative HPLC. The structures were identified on the basis of physicochemical properties and spectroscopic data. Result: Five isoflavone glycosides were isolated and identified as 6"-O-xylosyl glycitin(1) 5
6
7
4'-tetrahydroxyisoflavone-6
7-di-O-β-D-glucopyra noside(2)
glycitin(3)
6"-O-xylosyltectoridin(4) and tectoridin(5). Conclusion: The compound 1 and 3 were isolated from flowers of P. lobata for the first time in domestic. The compound 1 and 2 were not report from other plants in domestic.
