Problems solved by technology

However, the disadvantage of the content determination method of a single component is that two test conditions are required, and the determination is performed twice, which is not only time-consuming and laborious, but also increases the error of the internal ratio of the three components.
[0004] In view of the fact that there is no determination method and standard for the content of volatile oil, atractylone and atractylodes lactone in the "Pharmacopoeia of the People's Republic of China (2005 Edition, Part One)", the same chromatographic conditions can be used for the one-time determination of Atractylodes atractylodes III and Atractylodes atractyloides in Atractylodes macrocephala. The method of I and atractylone has not been reported

Abstract

The invention discloses a method of single time measurement of atractylenolide and atractylon. The procedure includes preparing mobile phase resolution A and B made of chromatographic pure methanol, acetonitrile and redistilled water, preparing the mixed control solution made of atractylenolide I, atractylenolide III and atractylon, preparing sample solution, testing the three absorption peaks of control solution and samples at three different time respectively by chromatograph of liquid according to the setting gradient of mobile phase A and B and the time, and calculating the content of atractylenolide I, atractylenolide III and atractylon according to the formula X=(peak area of sample is multiplied by density of control then is divided by peak area of control and is multiplied by density of sample) is multiplied by 100 percent. The invention can determine the content of atractylenolide I, atractylenolide III and atractylon in atractylodes macrocephala by only one sample injection. Thus the operation is simplified, the error of multiple sample injection is reduced and analysis of the constituent ration of the three ingredients is convenient. The invention is of important academic value and meaningful in practical application.

Description

technical field [0001] The invention relates to a method for determining atractylactone and atractylone, in particular to a method for one-time determination of atractylactone and atractylone by using an HPLC microtube method. The invention belongs to the technical field of determination of traditional Chinese medicine components. Background technique [0002] The traditional Chinese medicine Atractylodes macrocephala is the dried rhizome of Atractylodes macrocephala (Rhizoma atractylodis macrocephala Koidz.) "Pharmacopoeia of the People's Republic of China", 2005 edition, part one. It is a well-known traditional multi-purpose commonly used traditional Chinese medicine, and is one of the "Eight Flavors of Zhejiang". It has the effects of invigorating the spleen and replenishing qi, drying dampness and diuresis, antiperspirant and antiabortive. It is planted in many provinces in China, and Zhejiang Province is one of the main producing provinces. The annual output of our pr...
