Abstract

A quantitative determination method for total flavonoids in blood-red hawthorn leaves recalculated as vitexin 2″-O-rhamnoside using difference spectrophotometry at 392 nm was developed. The error of a single determination of total flavonoids in blood-red hawthorn leaves was ± 1.57% with confidence probability 95%. The contents of total flavonoids in blood-red hawthorn leaves varied from 2.65 ± 0.05 to 3.53 ± 0.06%.
