Problems solved by technology

[0005] Patented a pharmaceutical composition and preparation process for treating rheumatism and rheumatoid diseases (CN1733025), which did not involve quality testing methods, patented a preparation method and quality control method of Tibetan medicinal bath powder (CN1660051), only determined ephedra The content of ephedrine hydrochloride, ephedrine hydrochloride and pseudoephedrine hydrochloride in ephedra are isomers with similar properties and can be transformed into each other under certain conditions, so only measuring ephedrine hydrochloride can not accurately control the quality of ephedra, so it is difficult to ensure the preparation safe and effective
No reports on more advanced quality control methods for the above-mentioned Wuwei Ganlu preparations were found in the literature search

Abstract

The invention discloses a quality detection method of a five-flavor manna medicine bath preparation. The five-flavor manna medicine bath preparation is made from raw materials of Juniperus formosana, ephedra, rhododendron anthopogonoide, myricaria and artemisia sieversiana according to a conventional method of pharmaceutics. On the basis of the primary standard, the thin layer chromatography of ephedra and rhododendron anthopogonoide is revised, the thin layer chromatography of Juniperus formosana and artemisia sieversiana is added. Under the simple and convenient condition of mobile phase, octyl silane bonding silica gel or phenyl bonding silica gel is used as filler, and simultaneously, the contents of ephedrine hydrochloride and pseudoephedrine hydrochloride in the ephedra are detected. The invention also provides a method for measuring the content of hyperoside in five-flavor manna preparation rhododendron anthopogonoide, thus ensuring the safety, effectiveness and controllability of product quality. By the quality detection method, the quality standard of the existing five-flavor manna medicine bath preparation is improved correspondingly.
