Abstract:Within 0.008-0.040 mg/mL linear range, the author aimed to set up an analytical method of UV spectrophotometric determination of total flavonoids in hawthorn, using aluminum nitrate sodium nitrite as chromogenic reagent. The results showed that the method was simple, rapid and accurate. The ethanol extraction process of the total flavonoids in hawthorn was also studied, optimizing for the best extraction process of hawthorn ethanol concentration was 60 % with reflux extraction twice, 1.5-2 h each time.
Keywords:total flavonoids  UV spectrophotometry  determinati on  ethanol extract
