Research Abstract |
To synthesize flavonoid-O-sulfates and flavonoid-O-glucuronides, flavanone, flavone, flavonol and isoflavone were reacted with a sulfur trioxide pyridine and an acetobromo-glucuronide methylester. The products were analyzed by HPLC and purified by Toyopearl HW40 column chromatography. Chemical structures of the products wereidentified by LCMS and 1H-NMR. The yields of flavonoid-sulfates were good but that of glucuronides were poor. The antioxidant activity and ACE inhibiting activity were decreased by sulfation and glucuronidation of flavonoid aglycones.
