Abstract:
Anthranilic acid in the leaves of Isatidis indigotica Fort. was determined by first orderderivative UV spectrophotometry. The average recovery was 96.66％ and the coefficient of deviation was1.09％. The method showed no significant difference as compared with high performance capillary elec-trophoresis at 95％ confidence level. The method is simple, rapid and accurate.
