Abstract: OBJECTIVE: To establish a method for determination of 10 ingredients such as gentiopicroside, sweroside, and mangiferin in India swertia, and settle the index components and their limits.METHOD: By Welch materials AQ-C18 column, determination was conducted by the gradient elution with methanol and 0.4% formic acid as mobile phase, with column temperature 30 degrees C, flow rate at 1.0 mL x min(-1), and 254 nm as the detection wavelength. RESULT: The linear relatives of 10 ingredients were good. The method showed the high precision and good reproducibility, and recovery rates were between 97% and 103%. The ingredients of market com-modities varied greatly. CONCLUSION: This method is simple, sensitive, reproducible, and applicable to the determination of the main ingredients in India Swertia. Sweroside and mango glycosides were suggested as the index components for determination in Jia Di (Swertia chirayita), and their content limits are not less than 0.1%, 0.3%, respectively.
