Abstract: With fresh leaves as test material, this study established a relatively stable system of callus culture for Hypericum attenuatum Choisy, and determined the content of total flavonoids and hypericin in callus. With MS as the basic culture medium, the effects of different hormone combinations were investigated on callus induction. The results showed that the optimum culture media for callus induction was MS + 2,4-D 4.0 mg/L + 6-BA 0.2 mg/L. The total flavonoids and hypericin of callus were extracted using ultrasonic method, respectively, using UV spectrophotometry and HPLC method for determination total flavonoids content and hypericin content in callus. The results showed that total flavonoids was 27.99 mg/g, and hypericin content was 0.515 mg/g in dry callus.

Key words: Hypericum attenuatum Choisy, callus, induction, total flavonoids, hypericin
