Objective : To investigate the stability of Qinling granules under normal temperature, high temperature and high humidity environment. Methods : From the aspects of high temperature and high heat, constant temperature and humidity, leaving samples to investigate three aspects, the quality stability of the celery granules was studied, and the content of total flavonoids was determined by the aluminum nitrate color method. Result : After being placed at room temperature for 2 years, the results of quality inspection and hygienic inspection of the Kobayashi granules were in line with the standard. After being placed at constant temperature and humidity for 3 months, the flavonoid content of the product was not reduced. The results of high temperature accelerated experiments show that in the range of 90 to 120°C, the flavone content decreases with increasing temperature, t(25°C) 0.99=3.72 (a). Conclusion :Jianling granules are stable in 2 years
