To study the chemical constituents of Lysimachia clethroide Duby.METHODS:
Chromatographic techniques,including MS and NMR,were used to isolate and purify the constituents based on column chromatography separation on silica gel,Sephadex LH-20 and Semipreparative RP-HPLC.RESULTS:
Eleven flavonoids were obtained and elucidated as kaempferol (1),kaempferol 3-O-?-D-glucopyranoside (2),kaempferol 3-O-?-D-galactoside (3),kaempferol 3-O-?-D-(6″-p-coumaroyl)-glucopyranoside (4),quercetin (5),Isorhamnetin (6) ,quercetin 3-O-?-D-galactoside (7),quercetin 3′-methoxy-3-O-?-D-galactoside (8),quercetin 3-O-?-D-(6″-p-coumaroyl)-galactoside (9),4′-methoxy-5,6-dihydroxyisoflavone-7-O-?-D-glucopyranoside (10),7-O-glucosyl liquiritigenin (11).CONCLUSION:
