Method for measuring contents of multiple components of taxillus sutchuenensis

Abstract

The invention belongs to the technical field of chemistry, and specifically relates to a method for measuring the contents of multiple components of taxillus sutchuenensis. According to the method, under same chromatographic conditions, the contents of quercetin, quercitrin, and avicularin of taxillus sutchuenensis are measured by liquid chromatography at the same time. High performance liquid chromatography (HPLC) is used to simultaneously measure the contents of quercetin, quercitrin, and avicularin of taxillus sutchuenensis. The detection method is simple and accurate, the repeatability isgood, and reference is provided for comprehensive evaluation and control on the quality of taxillus sutchuenensis.

Description

【Technical field】 [0001] The invention relates to the technical field of chemistry, in particular to a multi-component content determination method of mulberry parasites. 【Background technique】 [0002] Sangji is the dry leafy stem branch of Taxillus chinensis (DC.) Danse. Harvest from winter to next spring, remove thick stems, cut into sections, dry, or steam and dry. The use of Sangjishen as medicine was first recorded in "Shen Nong's Materia Medica", named "Sangshangjishen", which was listed as top grade. "Famous Doctors Bielu" says: "A twig grows on the mulberry tree in Hongnongchuan Valley, and the stems and leaves are picked on March 3, and dried in the shade." On trees such as maple, the seeds are yellow and as big as jujubes. But there are mulberry trees in Guozhou, the seed juice is very sticky, and the core is as big as a small bean; the leaves have no yin and yang, and are thick like thin willow leaves; the late stems are thick and short. It is irrelevant to in...

Problems solved by technology

[0004] At present, the quality control of Sangjizi medicinal materials is relatively simple, and only the content of quercetin and / or quercetin can not be fully and clearly evaluated for the quality control of Sangjisheng medicinal materials. Lili et al., "China Health Industry", 2015, 12(27): 126-128) disclosed that the HPLC method was used to determine the content of quercetin in Mulberry, which can only be used to distinguish Mistletoe from Mistletoe

The literature "Comparison of Extraction Methods for the Determination of Quercetin and Quercetin Content in Mulberry by RP-HPLC" (Su Benwei et al., "Guangxi Traditional Chinese Medicine", 2012,35(4):53-55) discloses the simultaneous determination of Mulberry The method of quercetin and quercetin content in the medium can only detect the two components of quercetin and quercetin, and the curative effect in clinical application is different due to the different content of agaricin in different host sources.
