Abstract

The present invention relates to a method for determining the fingerprint of Tongluo Huatan Capsules. The steps of the method are as follows: (1) Preparation of the test solution: take the content of Tongluo Huatan Capsules, add methanol, ultrasonically extract, filter, Take the continued filtrate to obtain the test solution; (2) Preparation of the reference solution: take tauroursodeoxycholic acid, gastrodin, danshensu sodium, tanshinone ⅡA, and salvianolic acid B dried under reduced pressure to constant weight. , protocatechualdehyde, ginsenoside Rb1, ginsenoside Rg1, notoginseng saponin R1, emodin, rhein reference substance, respectively add methanol to make reference substance solution; (3) determination: precision measure the test solution and The reference substance solution is injected into a high-performance liquid chromatograph for measurement, and the chromatogram is recorded; (4) according to the chromatogram and the standard control fingerprint, it is compared, and if it is consistent, it is a qualified product.

Description

technical field [0001] The invention relates to a detection method of a medicinal preparation, in particular to a detection method of a fingerprint of a traditional Chinese medicine preparation Tongluo Huatan Capsule.
