Analytical method for rapidly identifying chemical components in Guangxi curcuma zedoary

Abstract

The invention provides an analytical method for rapidly identifying chemical components in Guangxi curcuma zedoary. The extract of Guangxi curcuma zedoary is obtained through supercritical carbon dioxide extraction. The extract is detected through an ultra performance supercritical fluid chromatography-quadrupole rod flight time spectrometry combination instrument, data processing can be carried out automatically through UNIFI software, automatic searching is realized inside a natural product database and a self-established curcuma chemical component database inside the UNIFI, the identification result is displayed automatically, and whether the structure is reasonable or not is also confirmed through the matching of a secondary fragment structure automatically. An online database can be searched automatically for components which cannot be identified through the internal natural product database and self-established curcuma chemical component database, and then the compounds are automatically confirmed through the matching of the secondary fragment structure. The method quickly and accurately realize detection and identification of the chemical components in Guangxi curcuma zedoary, and the method has the advantages of being accurate, simple in operation, high in flux, high in efficiency, green, environmentally-friendly and the like.

Description

technical field [0001] The invention relates to a method for identifying and analyzing chemical components of plant extracts, in particular to an analyzing method for rapidly identifying chemical components in Curcuma zedoary. Background technique [0002] Guangxi Zedoary (Curcuma kwangsiensis S.G.Lee&C.F.Liang) is a plant of the Zingiberaceae Curcuma genus, a perennial herb, produced in Guangxi and Yunnan, my country, cultivated or wild in hillside grasslands and bushes. The rhizome of this species is a kind of Chinese medicine Curcuma. The 2015 edition of "Chinese Pharmacopoeia" records that its nature, flavor and meridian distribution are pungent, bitter, and warm. Return liver, spleen channel. Function and indications are promoting qi and breaking blood, eliminating stagnation and relieving pain. For abdominal mass in the abdomen, amenorrhea due to blood stasis, chest pain and heartache, dyspepsia and distending pain. Modern pharmacological research has found that th...

Problems solved by technology

Traditional chemical composition analysis methods are complex, time-consuming and inefficient

At present, there are the following three methods for the research on the chemical components of Curcuma zedoary in Guangxi: 1. Purchase relevant reference substances and compare them with the components in the samples. The disadvantage of this method is that it is costly and most of the chemical components do not have reference substances.

2. Use various separation and preparation methods to separate and purify the components. The disadvantage of this method is that it is blind and takes too long

There are many kinds of compounds in Ezhu in Guangxi, with large differences in polarity and content, and there are a large number of isomers, so it is particularly difficult to separate and identify them

Existing methods can not solve the material matrix study of complex matrix Ezhu Guangxi
