Abstract

The invention discloses a multicomponent simultaneous assay method and a fingerprint spectrum construction method of callicarpa kwangtungensis and applications thereof. The assay method includes the steps of performing ultrafast liquid chromatographic detection and high-separation-degree fast liquid chromatographic detection or ultra-high performance liquid chromatographic method to a sample solution of the callicarpa kwangtungensis. The fingerprint spectrum construction method of the callicarpa kwangtungensis includes the steps of (1) detecting the callicarpa kwangtungensis with the detection method, and (2) generating a fingerprint spectrum of the callicarpa kwangtungensis with similarity evaluation software. The assay method of the callicarpa kwangtungensis is simple in operation, is excellent in stability, precision and repeatability, is good in chromatographic peak separation degree of the callicarpa kwangtungensis and is short in analysis time. The obtained fingerprint spectrum of the callicarpa kwangtungensis can be used for controlling the quality of the callicarpa kwangtungensis comprehensively so that quality controlling of the callicarpa kwangtungensis is more comprehensive and scientific.

Description

technical field [0001] The invention relates to a method for simultaneously measuring multiple components of Guangdong purple pearl, a method for constructing a fingerprint spectrum and an application thereof. Background technique [0002] Fingerprints can be represented by common peaks of different characteristics, which can basically reflect the chemical composition and content distribution of traditional Chinese medicines. The United States, the United Kingdom, India, Germany, Canada and other countries have accepted the quality control method of fingerprints. The components represented by each peak in the fingerprints do not require a clear chemical structure, nor do they need to be identified. Each component represented in the fingerprint is clearly quantified, and only the fingerprints of different batches of the same drug product need to be consistent. For example, the standard formulated by Germany and France for its Ginkgo biloba standard preparation EGb761 not onl...
