Methods Samples were ultrasonically extracted with 50% ethanol. The extracts were separated by SUPELCO-C18 column with gradient elution and methanol-water as the mobile phase, then samples were detected between 0~25 min at a wavelength of 230 nm and 25.01~39 min at a wavelength of 430 nm. Results Puerarin, paeoniflorin and curcumin could be completely separated by the conditions. The linear range was 0.01~0.1 mg
