Problems solved by technology

[0004] The present invention aims at joint pain relief ointment as a combination of traditional Chinese medicine and western medicine. The coating of the samples is carried out at high temperature, and all the active substances are in the colloid. It is difficult to separate them by the existing thin-layer identification and determination method when analyzing the active ingredients of the medicine. The extraction of atropine sulfate and diphenhydramine hydrochloride leads to the inability to obtain more accurate results. A TLC method for the determination of atropine sulfate and diphenhydramine hydrochloride in joint pain relief ointment is provided

Abstract

The invention relates to the technical field of effective components of medicines, and in particular relates to a thin-layer determination method for atropine sulfate and diphenhydramine hydrochloridein a joint pain-relieving paste; the method comprises a thin-layer identification and measurement method of atropine sulfate and a thin-layer identification and measurement method of diphenhydraminehydrochloride. By aiming at the characteristics of all pharmaceutical ingredients in the joint pain-relieving paste, suitable extraction and preparation processes and needed preparations are providedbased on the thin-layer identification characteristics of atropine sulfate and diphenhydramine hydrochloride, so that components to be measured can be separated and extracted from a plurality of effective pharmaceutical ingredients of the joint pain-relieving paste to complete the thin-layer identification determination. The preparation method solves the problems that a relatively accurate resultcannot be obtained when atropine sulfate and diphenhydramine hydrochloride are singly extracted by the existing thin-layer identification and measurement method through medical effective ingredient analysis caused by the fact that sample coating in the traditional Chinese medicine and western medicine combination paste in the joint pain-relieving paste is all carried out at a high temperature, andall effective components are in colloid.

Description

Technical field [0001] The invention relates to the technical field of active ingredients of medicines, in particular to a thin-layer determination method for atropine sulfate and diphenhydramine hydrochloride in joint pain relief ointment. Background technique [0002] Joint Pain Relief Ointment is a common Chinese patent medicine, which contains pepper liquid extract, belladonna liquid extract, peppermint oil, methyl salicylate, camphor, iodine, potassium iodide, atropine sulfate and diphenhydramine hydrochloride. The auxiliary materials are: rubber, zinc oxide, rosin, petroleum jelly, lanolin. It has the function of promoting blood circulation, anti-inflammatory, analgesic, and expanding local blood vessels. Used for joint sprains and joint pain caused by cold and dampness. [0003] Since the joint pain ointment is a combination of Chinese and Western medicine, the sample application is carried out at high temperature, and all the effective substances are in the colloid. It is...
