Detection method of yupingfeng oral liquid

Abstract

The invention relates to a detection method of a yupingfeng oral liquid. A thin layer chromatography is adopted, the same sample pretreatment method and the same chromatographic condition are used, and astragali radix and saposhnidoviae radix in a yupingfeng oral liquid prescription are simultaneously identified on the same thin layer plate. The method of identifying the astragali radix and the saposhnidoviae radix by the thin layer chromatography comprises the steps of (1) test solution preparation, (2) reference solution preparation, and (3) thin layer chromatography conditions and result. According to the detection method, the quality standard of the yupingfeng oral liquid is improved and perfected, and the identification of the saposhnidoviae radix is revised from a high performance liquid chromatography to a thin layer identification method, so that the identification time is greatly shortened, and the detection cost is lowered. Compared with a method in the prior art, the detection method is simpler, more convenient, rapider and more economical; the quality is easier to control; and the detection method is more suitable for industrial production.
