Abstract

Mesoporous SiO2 was synthesized and used for modification of the surface of a carbon paste electrode CPE In pH 80 phosphate buffer an irreversible oxidation peak at 038 V is observed for hesperidin Compared to the unmodified CPE the modified CPE remarkably increases the oxidation signal of hesperidin The effects of pH value amount of mesoporous SiO2 and accumulation time were examined As a result a sensitive and convenient electroanalytical method was developed for hesperidin Its linear range is from 05 to 25 μM and the limit of detection is 025 μM The method was applied to determine hesperidin in several traditional Chinese medicines
