Abstract

The invention belongs to the technical field of pharmaceutical analysis and relates to a fingerprint spectrum of an immature bitter orange medicinal material and a construction method and application of the fingerprint spectrum. Specifically, the invention relates to a high performance liquid chromatography (HPLC) fingerprint spectrum of the immature bitter orange medicinal material and a construction method of the fingerprint spectrum, as well as application of the HPLC fingerprint spectrum and/or a standard fingerprint spectrum of the immature bitter orange medicinal material in identification of the immature bitter orange medicinal material. The method for constructing the HPLC fingerprint spectrum of the immature bitter orange medicinal material specifically comprises the following steps: (1) preparing an immature bitter orange test sample; and (2) performing HPLC analysis. The invention also relates to a method for identifying the immature bitter orange medicinal material. The method is applied to identifying the authenticity and quality of the immature bitter orange medicinal material.

Description

technical field [0001] The invention belongs to the technical field of drug analysis, and relates to a fingerprint of citrus citrus medicinal material, its establishment method and application. Specifically, the present invention relates to a high-performance liquid chromatography (HPLC) fingerprint of Citrus aurantium medicinal material and its establishment method, and the use of HPLC fingerprint and / or standard fingerprint of Citrus aurantium medicinal material in identifying medicinal material of Citrus aurantium. The invention also relates to a method for identifying the quality (whether qualified or not) of the citrus citrus medicinal material. Background technique [0002] Traditional Chinese medicine fingerprint refers to the spectrum of common peaks that can indicate the characteristics of the Chinese medicinal material or Chinese patent medicine obtained after appropriate processing of a certain (or a certain place of origin) Chinese medicinal material or Chinese p...
