Abstract

The invention relates to a finger-print spectrum mutual mode construction method and a quality detection method of chrysanthemum cell-disruption decoction pieces. In the method, with isochlorogenic acid A as a contrast peak, mutual mode standard spectrums and determination indexes are established through HPLC analysis to not less than 10 batches of the samples under following chromatographic conditions: column temperature: 35 DEG C; wavelength: 348 nm; mobile phase: an acetonitrile-0.5% phosphoric acid solution; elution gradient: 0-8 min-24 min-50 min-75 min; and acetonitrile change: 14%-18%-18%-25%-45%. The spectrums of the samples to be detected under the same chromatographic condition are compared with the mutual mode standard spectrums to detect the quality of the samples to be detected. The invention firstly discloses the HPLC finger-print spectrum and the quality detection method aiming to the chrysanthemum cell-disruption decoction pieces. The spectrums comprehensively contain the spectrum information of main active components of the chrysanthemum cell-disruption decoction pieces. The method is strong in specificity, is quick and accurate in detection, and can effectively control the total quality of medicines, cell-disruption powders and cell-disruption decoction pieces.

Description

Technical field [0001] The present invention relates to a quality detection method of traditional Chinese medicine decoction pieces, in particular to the construction of HPLC fingerprint standard atlas of chrysanthemum-broken decoction pieces and its quality detection method. Background technique [0002] Chrysanthemum is the dried flower head of Chrysanthemum Chrysanthemummorifolium Ramat. Chinese herbal medicine broken wall pieces are the use of modern ultrafine pulverization technology to break the cell wall of traditional medicine pieces into fine particles with a particle size distribution D90 of less than 45μm, and then make particles with 30-100 mesh. Compared with traditional decoction pieces, it has the same color and luster, uniform quality and good stability. It is an innovative Chinese medicine decoction piece. Since the broken pieces of traditional Chinese medicine do not have the morphological characteristics of traditional Chinese medicine pieces, the dissolution ...
