Abstract

The invention relates to the technical field of detection of a traditional Chinese medicinal material, and particularly discloses an HPLC fingerprint spectrum of a pouzolzia zeylanica var. microphylla medicinal material or general flavonoids of pouzolzia zeylanica var. microphylla and a building method and application of the HPLC fingerprint spectrum. The building method comprises the following steps: S1, precisely weighing a pouzolzia zeylanica var. microphylla medicinal material to prepare a to-be-tested solution; and S2, enabling the to-be-tested solution to be subjected to high performance liquid chromatography to obtain a fingerprint spectrum. The fingerprint spectrum can overall reflect information of characteristic peaks of a reaction sample, and the method is good in stability and reproducibility. The fingerprint spectrum can be used for true and false or quality identification of the pouzolzia zeylanica var. microphylla medicinal material or general flavonoids of pouzolzia zeylanica var. microphylla.

Description

technical field [0001] The invention relates to the technical field of detection of traditional Chinese medicinal materials, in particular to an HPLC fingerprint spectrum of a medicinal material or total flavonoids of Pueraria japonica and its establishment method and application. Background technique [0002] Multibranch Mishuige (scientific name: Pouzolzia zeylanica var. microphylla) is a variety of Urticaceae Mishuige. Widely distributed in tropical Asia, produced in southeastern Yunnan, Guangxi, Guangdong, Fujian, southern Jiangxi, and Taiwan; it has detoxification and anti-inflammatory effects; it is used to treat boils and sores. Flavonoids are one of the active components of Pueraria twigs. At present, there is a lack of an accurate method for detecting the authenticity and quality of the medicinal materials of Pueraria radiata and the quality of the total flavonoids of Pueraria variegata. [0003] Traditional Chinese medicine fingerprint refers to the spectrum of c...
