Abstract

The invention provides an identification method for south radix isatidis in a Chinese herbal compound. The method mainly includes the steps of: first preparing a south radix isatidis reference solution, a test solution, and a negative sample solution free of south radix isatidis, and applying them on one silica gel G thin layer plate in order, then preparing a developing agent of certain proportion to develop the thin layer plate, finally inspecting the thin layer plate and carrying out identification. Specifically, in a test sample chromatogram, fluorescent principal spots in one color are displayed at positions corresponding to those of a reference sample chromatogram, and a negative sample has no display of such spots. With the advantages of simple and fast operation, good separation effect, strong specificity, and wide application, etc., the method provided in the invention is also in favor of perfecting drug quality standards related to south radix isatidis at the same time.

Description

technical field [0001] The invention relates to a method for identifying Radix Isatidis in a compound Chinese medicine, in particular to a thin-layer identification method for Radix Radix in Radix Zhongnan in a compound Chinese medicine. Background technique [0002] Nanbanlangen is the dried rhizome and root of Baphicacanthus cusia (Nees) Bremek., a plant of the genus Baphicacanthus cusia (Nees) Bremek. It is mainly produced in Guangdong, Guangxi, Fujian, Sichuan and other places.
