Problems solved by technology

In the actual process of multi-index component determination of traditional Chinese medicine preparations, the insurmountable bottleneck is the lack of some standard products, which directly limits the idea of ​​using conventional external standard method or internal standard method to achieve multi-index quality control.
The material basis of the anti-lung cancer effect of Ke formula has been systematically studied, and the active ingredients of flavonoids have been clarified [Dong Jing, Yin Lian, Zhang Xu, et al. Zhou Shi Ke Jinyan formula anti-lung cancer A9 cell effective part I component analysis research, China Zhong Journal of Medical Information, 2009, 16(11): 40-42; Sun Yi, Zhao Qin, Yin Lian, et al. Research on Anti-proliferation of A549 Cells Extracted from Zhoushi Kejinyan Formula, Journal of Nanjing University of Traditional Chinese Medicine, 200925(2 ): 107-109.], but the preparation and related medicinal materials have no quality control methods for multi-index components

Abstract

The invention discloses a quality control method for 10 index components of a traditional Chinese medicine conquering prescription for treating lung cancer. The method comprises the following steps: (1) extracting a test solution for preparing medicinal materials of the conquering prescription or preparation; (2) detecting hybrid reference substances catechinic acid, hyperin, rutin, isoquercitrin, galuteolin, quercitrin, apigenin-7-O-glucoside and quercetin chromatogram by adopting a liquid chromatography, and respectively calculating relative correction factors fkm of other components relatively to the quercetin by employing the quercetin as an internal standard compound; and (3) detecting the chromatogram of the test solution of the conquering prescription by the liquid chromatography, calculating the content according to the regression equation by employing the quercetin as an internal standard, and calculating the contents of other 9 components according to the peak area and the relative correction factors. Compared with the internal standard method, the method is accurate and reliable in data, high in detection sensitivity, and simple and convenient in method, and has relatively good adaptability on different model numbers of high performance liquid chromatographs and chromatographic columns; the problem that the medicinal material of the conquering prescription and the preparation quality of the medicinal material cannot be objectively and reasonably controlled due to shortage of reference substances can be solved; and the quality control method has important significance on control of the medicinal materials of the conquering prescription and the preparation quality and guarantee of the curative effect.
