| Abstract: | This paper refers to the improvements on the traditional method for synthesis of flavone-glycosides. 7-Hydroxyflavone glucoside and 7-hydroxyflavone arabinoside were synthesized by means of the solid-liquid phase transfer catalysis from 1-bromo- 2,3,4,6-tetra- O-acetyl-a-D-glycopyranose and 7-hydroxyflavone using tetrabutylamino bromide as the phase transfer catalyst and potassium carbonate as the base. The title compound is a novel compound that has not been reported previously. Besides, the ef- fects of reaction mode, temperature, and different types of saccbarides on the product yield were also studied and reported. |
