A method for the determination of ferulic acid content in angelica decoction pieces

Abstract

The invention discloses a determination method for the content of ferulic acid in Chinese angelica decoction pieces, belonging to the technical field of detection of the quality of traditional Chinese medicinal materials. The method comprises the following steps: 1) drying of a sample; 2) preparation of the Chinese angelica decoction pieces; 3) preparation of sample powder; 4) preparation of a solution of a to-be-tested sample; 5) preparation of a solution of a control sample; and 6) determination. According to the invention, fresh Chinese angelica is dried at low temperature and the decoction pieces are prepared from the dried fresh Chinese angelica, so components in the Chinese angelica are maximally retained, and the quality of the Chinese angelica decoction pieces is improved; and since white gauze is used to cover the Chinese angelica, the dehydration speed of the epidermis of the Chinese angelica is lowered and components in the Chinese angelica flow along with moisture, so relative equalization of components at each part of the Chinese angelica is maintained and detection results of the prepared sample powder are relatively stable.

Description

technical field [0001] The invention belongs to the technical field of quality detection of traditional Chinese medicinal materials, and in particular relates to a method for determining ferulic acid content in angelica decoction pieces. Background technique [0002] The quality of Chinese medicinal materials is not only affected by factors such as variety, place of origin, and harvesting season, but also has a lot to do with whether the processing method in the place of origin is appropriate. At present, the processing of traditional Chinese medicinal materials in my country is mostly "decentralized processing" mode. Due to the differences in production and processing technology and the lack of standardized production, sulfur fumigation is even used in some areas, resulting in uneven quality of processed decoction pieces, and adulteration in the market is also common. It affects the clinical curative effect of traditional Chinese medicine. At the same time, with the continu...

Problems solved by technology

The method detects the content of ferulic acid by high-performance liquid chromatography, which is accurate, simple and easy to implement. However, since "Danggui slices" are fresh-cut thick slices and dried, it is different from the existing conventional production and processing methods of Angelica sinensis. In the sample solution prepared by Danggui Tablets, due to the complex moisture content and components, it is inevitable that there will be errors in the determination by conventional methods, and the existing Chinese Pharmacopoeia does not have an assay standard for "Danggui Tablets". Therefore, a method for the determination of "Danggui Tablets" is provided. standards are necessary
