Abstract
The application relates to the technical field of traditional Chinese medicine detection and analysis chemistry, in particular to a fingerprint construction method and an identification method of traditional Chinese medicine materials and traditional Chinese medicine preparations, and particularly relates to a fingerprint construction method of angelica sinensis or preparations thereof, angelica sinensis charcoal or preparations thereof, an identification method of angelica sinensis and angelica sinensis charcoal, and an identification method of angelica sinensis preparations and angelica sinensis charcoal preparations. The fingerprint construction method comprises the steps of adopting ultra-high performance liquid chromatography to analyze, wherein the chromatographic condition is that acetonitrile is used as a mobile phase A, and formic acid aqueous solution with the volume concentration of 0.08-0.12% is used as a mobile phase B. The fingerprint of the application has characteristics, reproducibility and operability, and can clearly determine the common components and the differential components of the angelica and the angelica charcoal. The identification method of the Chinese medicinal preparation can effectively identify the Chinese medicinal preparation and the Chinese medicinal charcoal preparation, and overcomes the defect that the Chinese medicinal preparation and the Chinese medicinal charcoal preparation cannot be checked and identified from microscopic and character identification features.
Description
Technical Field
The application relates to the technical field of traditional Chinese medicine detection and analysis chemistry, in particular to a fingerprint construction method and an identification method of traditional Chinese medicine materials and traditional Chinese medicine preparations, and particularly relates to a fingerprint construction method of angelica sinensis or preparations thereof, angelica sinensis charcoal or preparations thereof, an identification method of angelica sinensis and angelica sinensis charcoal, and an identification method of angelica sinensis preparations and angelica sinensis charcoal preparations.
Background
Angelica sinensis is derived from dried roots of Angelica sinensis ANGELICA SINENSIS (Oliv.) Diels, an Umbelliferae plant. Sweet and pungent in flavor, warm in nature, enter liver, heart and spleen meridians. Has effects of replenishing blood, promoting blood circulation, regulating menstruation, relieving pain, loosening bowel, and relieving constipation. Mainly contains volatile oil, organic acid, amino acid, saccharide, etc. The hemostatic effect of stir-baked Chinese angelica is enhanced, and is mainly used for treating metrorrhagia, metrostaxis, menorrhagia and the like. The clinical effects and the main chemical components of the two medicines are different to a certain extent, so that the chemical component difference of the Chinese angelica before and after the charcoal is fried is clear, and the medicine has an important effect on researching the medicine property of decoction pieces.
A method for constructing the fingerprint of angelica sinensis is reported, but the method has less common peak calibration and identification number, and cannot realize the spectrum analysis of all components.
The Chinese medicine preparation is prepared with Chinese medicine product as basic material and through extraction, separation and purification to obtain semi-product, and other steps. Compared with decoction pieces, the traditional shape and characteristics of the decoction pieces are lost, and after extraction, the decoction pieces have certain differences with chemical components of medicinal materials. At present, identification methods of angelica sinensis or angelica sinensis charcoal preparations are not reported.
Therefore, it is necessary to establish a scientific method for detecting and identifying angelica or its preparation, angelica charcoal or its preparation.
Disclosure of Invention
In view of this, the application provides a method for constructing fingerprint of Chinese medicinal materials or Chinese medicinal preparations, which can objectively, scientifically and comprehensively reflect the intrinsic chemical characteristic information of Chinese medicinal materials and/or Chinese medicinal preparations as the basis for quality detection. The Chinese medicinal materials comprise angelica and angelica charcoal, and the Chinese medicinal preparation comprises an angelica preparation and an angelica charcoal preparation.
Specifically, the fingerprint construction method comprises the following steps:
extracting the traditional Chinese medicinal materials or the traditional Chinese medicinal preparation with an extraction solvent to obtain a sample solution;
taking the sample solution for ultra-high performance liquid chromatography analysis to obtain the fingerprint of the traditional Chinese medicine or the traditional Chinese medicine preparation;
wherein the performing of the ultra performance liquid chromatography analysis comprises eluting according to mobile phase conditions as follows: acetonitrile is taken as a mobile phase A, formic acid aqueous solution with the volume concentration of 0.08-0.12% is taken as a mobile phase B, and the sum of the volume percentages of the mobile phase A and the mobile phase B is 100%;
The elution procedure includes:
0-12 min, wherein the volume percentage of the mobile phase A is increased from 5% to 23%;
12-13 min, wherein the volume percentage of the mobile phase A is increased from 23% to 43%;
13-18 min, wherein the volume percentage of the mobile phase A is increased from 43% to 44%;
18-20 min, wherein the volume percentage of the mobile phase A is increased from 44% to 46%;
20-22 min, wherein the volume percentage of the mobile phase A is increased from 46% to 47%;
22-23 min, wherein the volume percentage of the mobile phase A is increased from 47% to 58%;
23-29 min, wherein the volume percentage of the mobile phase A is increased from 58% to 59%;
29-30 min, wherein the volume percentage of the mobile phase A is increased from 59% to 80%;
And (3) keeping the volume percentage of the mobile phase A at 80% for 30-34 min.
