Abstract

The invention relates to a measurement method for the content of atropine sulfate in traditional Chinese medicine suppository containing belladonna liquid extract. The invention solves the problem that only the existence of atropine sulfate in traditional Chinese medicine suppository containing belladonna liquid extract the traditional can be detected in the field of traditional Chinese pharmacy,and the content of the atropine sulfate cannot be detected. In the method, chromatograph conditions are controlled, comparison product and test article solutions are prepared, the comparison product solution and the test article solution are respectively absorbed, and the content of the atropine is measured by a high performance liquid chromatography method by adopting an external standard methodby using a liquid chromatograph. The content of the atropine can be precisely measured. The main peak and front and back separation effect is good, and the number of theoretical plates is high. The invention has important meaning for controlling the quality of the traditional Chinese medicine suppository.

Description

technical field [0001] The invention relates to a detection method of a compound traditional Chinese medicine preparation, in particular to a detection method of atropine sulfate content in a traditional Chinese medicine suppository containing belladonna liquid extract. Background technique [0002] Belladonna liquid extract is a brown liquid with a slightly smelly gas. It is a preparation obtained from belladonna leaves according to the liquid extract method. It mainly contains alkaloids such as hyoscyamine and atropine. It has the functions of relieving spasm of smooth muscle, inhibiting gland secretion, relieving the inhibition of vagus nerve on the heart, accelerating heartbeat, dilating pupils, increasing intraocular pressure, and stimulating the respiratory center. Therefore, belladonna liquid extract also has the effect of relieving smooth muscle spasm and inhibiting gland secretion, and is often used to make various traditional Chinese medicine preparations. For exa...
