Problems solved by technology

[0004] At present, in the existing research on the fingerprints of Qingpi, there are gas chromatography to establish fingerprints for volatile oil components, and there is no lack of liquid phase technology for quality control, but there are too few common peaks in the chromatograms, and the characteristic fingerprints of Qingpi cannot be established. Map, easy to mix with medicinal materials such as Citrus aurantium and Citrus aurantium

Abstract

The invention discloses a method for establishing a fingerprint of a green tangerine peel medicinal material and a fingerprint thereof, and relates to the technical field of fingerprints of Chinese medicinal materials. The method comprises the steps of (a), preparation of a reference solution; (b), preparation of a test solution; (c), HPLC detection conditions; (d), formulation of a standard fingerprint with hesperidin as a reference peak; (e), quality control of the fingerprint. According to the method, a pretreatment method for each test product is simple, characteristic components are completely reserved, the repeatability and stability are good, the degree of precision is high, and there is a certain specificity; the separation effect of each characteristic peak in the obtained fingerprint is good; the method can be used for identifying the authenticity and quality of the green tangerine peel medicinal material.

Description

technical field [0001] The invention relates to the technical field of fingerprints of traditional Chinese medicinal materials, in particular to a method for establishing fingerprints of green bark medicinal materials and the fingerprints thereof. Background technique [0002] The fingerprint of Chinese herbal medicine refers to the spectrum that can mark the characteristics of the Chinese herbal medicine, which is obtained by using certain analytical methods and testing instruments after proper treatment of the Chinese herbal medicine. One of the means has also been recognized by the international community. [0003] Qingpi is a commonly used traditional Chinese medicine, mainly the green peel of dried young fruit or immature fruit of Rutaceae plant orange (Citrus reticulata Blanco) and its cultivars. Qingpi is mainly divided into Sihuaqingpi and Geqingpi. From May to June every year, collect the young fruit that falls from the sun, and dry it in the sun, which is commonl...
