Objective : To determine the content of Qinghuo buckwheat capsules by high performance liquid chromatography and investigate its stability. Methods: The content of andrographolide was determined by high performance liquid chromatography. The UV detection wavelength is λ2 2 5 nm. Accelerated stability test environment: 3 9°C, relative humidity 75%, 1 assessment per month. RESULTS AND CONCLUSION: This product contains accurate results, precision, recovery and reproducibility are good. After accelerated stability test, after 3 months of placement, the content of andrographolide decreased by about 50%.
