Quality Control Method of Cimicifuga Gegen Decoction Composition

Abstract

The invention discloses a quality control method for a rhizoma-cimicifugae and kudzu-vine-root soup composition, and belongs to the field of traditional Chinese medicine analysis. According to the quality control method, a fingerprint spectrum is established with the efficient liquid chromatography, wherein the chromatographic conditions are characterized in that a chromatographic column is an octadecyl silane bonded silica gel chromatographic column, the flow speed is 0.9 ml / min to 1.1 ml / min, the column temperature is 25 DEG C to 35 DEG C, a detection instrument is an ultraviolet detector, the detection wavelength is 210 nm to 250 nm, the theoretical plate number is higher than or equal to 4,000 according to puerarin peaks, a reference solution is a daidzin methanol solution, and a flowing phase system is acetonitrile-0.1%-phosphoric acid solution and is eluted in the following order (please see the specification). The fingerprint spectrum comprehensively reflects the quality information of rhizoma-cimicifugae and kudzu-vine-root soup, and therefore the aim of more comprehensively and efficiently controlling the quality of rhizoma-cimicifugae and kudzu-vine-root soup preparation products can be achieved.

Description

technical field

[0001] The invention belongs to the field of analysis of traditional Chinese medicines, and in particular relates to a quality control method for the composition of Cimicifugae Radix and Root Decoction. Background technique

[0002] Traditional Chinese medicine decoction is the mainstream of clinical medicine, but because of decoction and inconvenient to carry, the quality of the decoction prepared by decoction often varies greatly depending on the person and the decoction utensils. The use of modern science and technology to develop traditional Chinese medicine preparations that are easy to carry and easy to take is not only the inheritance of traditional Chinese medicine, but also a better promotion of classic famous prescriptions. Clinical application. The preparation process of granules is relatively simple, easy to shape, easy to take and carry, and the form of taking is most consistent with traditional decoctions, and can maintain the characteristics o...
