Abstract
The invention discloses a method for detecting the characteristic spectrum of a traditional Chinese medicine composition for treating irregular menstruation, and belongs to the technical field of quality detection of traditional Chinese medicine preparations. The invention adopts high-performance liquid chromatography, under the same chromatographic condition, and takes neohesperidin as a reference, to carry out qualitative analysis on the components contained in the sample. The detection method is simple and fast, has good sensitivity and high stability, improves the effective control of the quality of medicines, and guarantees the quality.
Description
technical field [0001] The invention relates to a method for constructing a characteristic map of a traditional Chinese medicine composition for treating irregular menstruation, and belongs to the technical field of quality detection of traditional Chinese medicine preparations. Background technique [0002] The traditional Chinese medicine composition involved in the invention is composed of motherwort, angelica, red peony and other traditional Chinese medicines, and is a good medicine for treating irregular menstruation of qi stagnation and blood stasis type. In the literature, there are many studies on the composition of this type of traditional Chinese medicine composition, but there are no reports on the use of characteristic maps to detect multiple components in the composition; the existing product detection methods are relatively simple and cannot fully control product quality Therefore, it is necessary to carry out relevant exploration and research on the quality de...
