Abstract

The invention belongs to the technical field of traditional Chinese medicine detection, and particularly relates to a motherwort fruit characteristic spectrum and a construction method thereof, a stachydrine hydrochloride content determination method, a motherwort fruit formula granule and a preparation method thereof. By controlling the gradient program, the reliable, stable and good-repeatability motherwort fruit characteristic chromatogram can be constructed by adopting a specific method, and a more scientific, reasonable and detailed basis is provided for quality control of motherwort fruits. According to the construction method, the peak appearance time is changed by adjusting the flow rate, the operation time is shortened, the method is easy to operate and implement, information of characteristic peaks of the motherwort fruits can be fully reflected, chemical component characteristics of the motherwort fruits can be displayed, good separation degree and peak shapes of main components can be kept, the motherwort fruits from different producing areas and the quality of the motherwort fruits can be comprehensively evaluated, and the method is rapid and effective.

Description

technical field [0001] The invention belongs to the technical field of detection of traditional Chinese medicines, and in particular relates to a characteristic map of Fructus Radix and its construction method, a method for determining the content of stachydrine hydrochloride, formula granules of Fructus Radix and a preparation method thereof; more specifically, it relates to Fructus Fructus The characteristic map of formula granules, decoction pieces, freeze-dried powder or medicinal materials and its construction method, the determination method of stachydrine hydrochloride content in Ziweizi, and the formula granules of Ziweizi and its preparation method. Background technique [0002] Leonurus japonicus Houtt. is the dried and mature fruit of Leonurus japonicus Houtt., a plant of the Labiatae family.
