ABSTRACT
To study the chemical constituents of the traditional Chinese herb Baeckea Frutescens L., a new flavonol glycoside, named 6, 8-dimethylkaempferol-3-O-alpha-L-rhamnoside (1), together with seven known compounds quercetin (2), quercetin-3-O-alpha-L-rhamnoside (3), myricetin (4), myricetin-3-O-alpha-L-rhamnoside (5), gallic acid (6), ursolic acid (7) and 1,3-dihydroxy-2-(2'-methoxylpropionyl)-5-methoxy-6-methylbenzene (8) were isolated by using silica gel column chromatography, polyamide column chromatography and recrytallization. Their structures were identified on the basis of physicochemical properties and spectroscopic analysis. Among them, compounds 2-7 were isolated from this plant for the first time and compound 8 was first isolated from plant.
