Abstract

The invention provides a method for determining the content of active ingredients in Chinese honeylocust fruit, which adopts ultra-high performance liquid chromatography-mass spectrometry. The content of L-malic acid, protocatechuic aldehyde, protocatechuic acid, caffeic acid, scopoletin, liquiritigenin, apigenin, luteolin, eriodictyol, citrus aurantium, fustin, cryptochlorogenic acid, neochlorogenic acid, chlorogenic acid, vitexin, isovitexin, quercitrin, orientin and isoorientin in the Chinese honeylocust fruit can be rapidly detected. The method provided by the invention has the advantages of simple operation, high sensitivity, fast analysis speed and strong specificity, and can be used for quality control of Chinese honeylocust fruit.

Description

technical field [0001] The application relates to the technical field of determination of traditional Chinese medicine ingredients, and in particular, to a method for determining the content of active ingredients in Saponin. Background technique [0002] Gleditsiae sinensis fructus, also known as acacia, flat saponin, is a plant of the genus Gleditsiae sinensis, and is one of the unique native tree species in China. It is distributed in most parts of the country and has abundant resources. It has the effects of dispelling wind and phlegm and removing dampness and toxin. After processing, it can reduce its toxic and side effects, and is often used in clinical medicine. Saponin has great medicinal value, but the quality of medicinal materials in different origins is uneven, so it is difficult to evaluate its quality. Therefore, an efficient, rapid, and highly sensitive detection method is required to determine the content of active ingredients in Saponin, and to provide a bas...
