A method for simultaneous detection of multiple components in Daqili preparation

Abstract

The invention belongs to the field of quality detection of traditional Chinese medicines, and specifically relates to a method for simultaneously detecting multiple components in Daqili preparations. The method adopts HPLC method to carry out content determination and result judgment on the mixed reference substance solution and the test solution respectively. Alkylsilane-bonded silica gel is used as a chromatographic column filler, acetonitrile is used as mobile phase A, 0.1% formic acid solution is used as mobile phase B, and gradient elution is carried out. The number of theoretical plates is not less than 4000 according to the peak of rhizoma glucoside; the control The product solution contains abietic acid, rhizomatin, ascarin B and 11-carbonyl-β-acetylboswellic acid. The present invention establishes a method capable of simultaneously detecting multiple components in Daqili preparations. The method has good separation effect, good repeatability, low detection limit, fast and accurate, simple and efficient, and low cost, and can be used as a method for controlling adulteration of Daqili preparations. The technical means of adulterating and irregular feeding.

Description

A method for simultaneous detection of multiple components in Daqili preparations technical field The invention belongs to the field of quality detection of traditional Chinese medicines, be specifically related to a kind of method for simultaneously detecting multiple components in Daqili preparations. Law. Background technique Daqili preparation includes Daqili powder, Daqili tablet, Daqili capsule and Daqili pill four dosage forms, and the prescription contains Rhubarb, dried blood, frankincense, myrrh, soft-shelled turtle, natural copper, drynaria, angelica tail, borax, panax notoginseng, borneol, and eleven herbs. The original powder is used as medicine. In recent years, driven by commercial interests, many counterfeit Chinese medicines have appeared on the market, among which Rhubarb, which is widely used, and frankincense, myrrh and dried blood, which have historically relied on imports and are in short supply. Polygonaceae plant palm leaves The dried root...

AI Technical Summary

Problems solved by technology

There are few reports on the quality research of Daqili preparations, especially the research on the adulteration and irregular feeding of Daqili preparations, which has not been reported in the literature

At present, for adulterated samples, only according to the current standard inspection items of Daqili preparations, the quality cannot be completely controlled, and the situation of irregular feeding cannot be identified.
