Problems solved by technology

The methods provided in the current literature are all universal detection methods for medicinal materials, and have not been studied for the special requirements of extended varieties
[0007] And the determination of general volatile components all adopts gas chromatography, but sometimes the detection high temperature of the gas phase (high temperature of the injection port) causes the degradation of some components, such as furadienes and furadienones in turmeric, which cannot accurately express the turmeric volatile components; therefore, the patent uses two detection methods, gas chromatography and liquid chromatography, to study the fingerprints of turmeric

Abstract

The invention relates to a determination method for radix curcumae fingerprint and a standard fingerprint thereof. The determination method comprises the following steps of preparing of a test samplesolution, preparing of a reference sample solution, determining by gas chromatography, and determining by liquid chromatography, so as to obtain a chromatogram map; contrasting the obtained standard radix curcumae gas fingerprint and the liquid fingerprint, wherein the qualified product is obtained when the obtained standard radix curcumae gas fingerprint is consistent with the liquid fingerprint.The determination method has the advantages that the determination method is simple, rapid, accurate, stable and reliable, and is used for controlling the quality of the radix curcumae; the quality of the radix curcumae can be more comprehensively, objectively and scientifically evaluated; the validity of the preparation is guaranteed.

Description

technical field [0001] The invention relates to a method for analyzing fingerprints of traditional Chinese medicines, in particular to a method for measuring fingerprints of turmeric, and the obtained gas-phase fingerprints and liquid-phase fingerprints of turmeric. [0002] technical background [0003] Turmeric has the effects of promoting blood circulation and relieving pain, promoting qi and relieving stagnation, clearing heart and cooling blood, promoting gallbladder and reducing jaundice. Blood-heat spits nosebleed, jaundice and red urine. It is used in Angong Niuhuang Pills, Shixiang Huisheng Pills, Niuhuang Qinggong Pills, Xingnaojing Injection, etc. [0004] There are three kinds of turmeric bases stipulated in the Chinese Pharmacopoeia, which are the dry root tubers of Curcuma wenyujinY.H.Chenet C.Ling, which is called Curcuma wenyujinY.H.Chenet C.Ling, and the main place of origin is Wenzhou, Zhejiang; the dry tuber roots of Curcuma longaL. Commonly known as yell...
