Problems solved by technology

[0003] Plants of the genus Jadeleaf and Cinnamonia are widely distributed in Guangxi and are widely used. The plant forms of different varieties are relatively similar, and their salient features are composed of a white deformed sepal and a few golden flowers. During the flowering season, the mountains and plains are full of , very eye-catching, but it is difficult for people who do not have professional knowledge of plant taxonomy to distinguish different species of Cinnamonia and Jadeleafia plants

Embodiment

[0015] Embodiment, content is as follows:

[0016] Reference substance: chlorogenic acid (provided by the China National Inspection Institute, batch number 110753-201415, with a content of 96.2%), 3,5- O -Dicaffeoylquinic acid (provided by the China National Inspection Institute, batch number 111782-201405, the content is calculated as 92.0%), 4,5- O - Dicaffeoylquinic acid (provided by the China Inspection Institute, batch number 111894-201102, the content is 94.1%).

[0017] The identification steps are as follows:

[0018] (1) Preparation of the test solution: Take 1 g of Cracked Golden Flower powder, add 20 mL of methanol, ultrasonically treat for 30 minutes, filter, evaporate the filtrate to dryness, add 2 mL of methanol to dissolve the residue, and use it as the test solution.

[0019] (2) Preparation of reference solution: take chlorogenic acid, 3,5- O -dicaffeoylquinic acid, 4,5- O - Dicaffeoylquinic acid reference substance, add methanol to make a mixed reference ...

Abstract

The invention discloses a thin-layer chromatography discriminating method of schizomussaenda dehiscens. According to the invention, schizomussaenda dehiscens is taken as a main component, a mixed solution of chlorogenic acid, 3,5-O-dicaffeoylquinic acid, and 4,5-O-dicaffeoylquinic acid is taken as a reference substance solution, and a thin-layer chromatography (Chinese pharmacopoeia 2015 edition general rule 0502) is referred for testing. The method has the advantages of convenient operation, simple equipment, easy color development, and fast expansion rate, and provides basis for discriminating the schizomussaenda dehiscens.

Description

technical field [0001] The invention relates to the technical field of traditional Chinese medicine identification, in particular to a thin-layer chromatographic identification method for the golden flower of cracked fruit. Background technique [0002] Cracking Golden Flower (Latin scientific name: Schizomussaenda dehiscens (Craib) H.L. Li) large shrub, up to 7-8 meters; shoots are strigillose, then nearly glabrous, light brown or grayish brown. Leaves are thin and papery, oblanceolate, oblong-oblanceolate or ovate-lanceolate.
