Method for identifying cyclocarya paliurus

Abstract

The invention discloses a method for identifying cyclocarya paliurus. The method comprises the following steps: (1) preparing a test solution; and (3) respectively preparing a methanol solution of kaempferide and a methanol solution of quercetin as reference substance solutions, respectively dripping the two reference substance solutions and the test solution on the same silica gel G thin-layer plate, developing by using dichloromethane-ethyl acetate-formic acid as a developing solvent, taking out, airing, spraying an ethanol solution of aluminum trichloride, heating the sample solution in the environment of 105 + / -5 DEG C until the spots are clearly developed, placing the sample solution under an ultraviolet lamp for inspection, and when the fluorescent spots in the chromatogram of the sample solution can find the corresponding fluorescent spots in the corresponding position of the chromatogram of one of the two reference substance solutions, determining that the powder to be detected is cyclocarya paliurus powder. The method is high in cyclocarya paliurus identification accuracy, meanwhile, the content of kaempferide in cyclocarya paliurus can be measured, the quality grade of cyclocarya paliurus can be evaluated, operation is easy, reaction is fast, and rapid detection and evaluation of the quality of cyclocarya paliurus are achieved.

Description

technical field [0001] The invention belongs to the technical field of identification of Cyclocarya paliurus beverages, and in particular relates to an identification method of Cyclocarya paliurus. Background technique [0002] Cyclocarya is a single-species plant of the Juglandaceae Cyclocarya genus, also known as sweet tea tree, money tree, green money plum, a string of money, mountain tree, camellia, and mountain hemp tree. Cyclocarya paliurus is scattered in the mountains, valleys or limestone mountains of Jiangxi, Jiangsu, Guangxi, Fujian, Zhejiang and other places in China. Residents in many places in Jiangxi often use its leaves as tea, believing that the leaves are sweet and moist, and have the effects of promoting body fluids and quenching thirst, clearing away heat and detoxification, and lowering blood pressure. At present, the amount of Cyclocarya paliurus is increasing, but there is no good identification method so far, so there are many counterfeit and inferio...

AI Technical Summary

Problems solved by technology

At present, the amount of Cyclocarya paliurus is increasing, but there is no good identification method so far, so there are many counterfeit and inferior products of Cyclocarya paliurus, which is not conducive to the embodiment of the value of Cyclocarya paliurus and the use and development of it.
