Problems solved by technology

[0004] In recent years, the pharmacognosy and chemistry of Zhuang medicine Ainaxiang Diangui are mainly characterized by character identification, microscopic identification and physical and chemical identification methods. The TLC identification method is also used in the drafting instructions of its quality standards, but these methods exist to provide The amount of information is small, the chemical composition of the sample is incomplete, and the number of identifiable components is small, so it cannot represent the overall quality of the Zhuang medicine Diangui Ainaxiang.

Abstract

The invention discloses a method for establishing an HPLC fingerprint spectrum of a Zhuang medicinal material Blumea riparia (Bl.) DC. By adopting a high-performance liquid chromatography, and using main ingredients such as protocatechuic acid and protocatechuic aldehyde of Blumea riparia (Bl.) DC as reference substances, a fingerprint spectrum of a common pattern of the Zhuang medicine Blumea riparia (Bl.) DC medicinal material is obtained. The fingerprint spectrum has 13 chromatographic peaks, can fully reflect the chemical compositions of the Blumea riparia (Bl.) DC medicinal material, and is rich in information amount, the method has good reproducibility, a more powerful theoretical basis is provided for controlling the quality of the medicinal material and identifying the advantages and disadvantages of the medicinal material, the quality control and the level of true and false identification of the Zhuang medicine Blumea riparia (Bl.) DC medicinal material are improved, and the authenticity and the advantages and disadvantages of the Blumea riparia (Bl.) DC can be quickly and accurately identified.

Description

technical field [0001] The invention belongs to the technical field of fingerprints of traditional Chinese medicinal materials in drug analysis, and in particular relates to a method for establishing HPLC fingerprints of the strong medicinal material Diangui Ainaxiang. Background technique [0002] Diangui Ainaxiang is the dry whole herb of Ainacaria genus Blumeariparia (Bl)DC in Compositae, and has a long history of use in Guangxi, especially in Baise. Diangui Ainaxiang is mainly produced in southwestern Guangxi (Baise, Debao, Lingyun), southern Guangdong, and southwestern to southeastern Yunnan. It has the effects of promoting blood circulation, stopping bleeding, and diuresis. Pregnancy, vaginal sores. [0003] Traditional Chinese medicine fingerprint refers to the spectrum or image of the common characteristics of each component group of traditional Chinese medicine obtained by modern analysis techniques such as spectrum or chromatography of Chinese medicinal materials ...
