Rapid calculation method of adulterated starwort root and adulteration amount in codonopsis pilosula decoction pieces

Abstract

The invention discloses a rapid calculation method of adulterated starwort roots and adulteration amount in codonopsis pilosula decoction pieces. The adulteration amount X of the starwort roots in thecodonopsis pilosula decoction piece and the peak area Y of the starwort root component in the chromatogram of the codonopsis pilosula decoction piece have a first-power function relationship and conform to the Lambert-Berr law. The established binary linear equation is shown in the description. In the formula, R2 represents the linear meeting and parting degree of X and Y, and the greater the R2is, the better the regression linear meeting and parting effect is. The technical scheme for detecting the adulterated starwort roots in the codonopsis pilosula decoction pieces by the high performance liquid chromatography (HPLC) conforms to the scientific theory; the method is simple and convenient in experimental operation, can complete sample detection in a short time, can simply, quickly andaccurately detect whether the codonopsis pilosula decoction pieces are adulterated with starwort roots or not and the adulteration proportion of the starwort roots, and provides a brand-new method fordetecting adulteration of the traditional Chinese medicine decoction pieces.

Description

technical field [0001] The invention belongs to the technical field of drug detection, in particular to a fast calculation method for adulterated silver bupleurum and adulterated amount in dangshen decoction pieces. Background technique [0002] Chinese medicinal materials and decoction pieces are important raw materials for clinical use of traditional Chinese medicine and production of Chinese patent medicines, an important part of my country's medical care and a treasure in the treasure house of medicine.

Codonopsis pilosula (Franch.) Nannf. , Codonopsis pilosula Nannf. var. modesta (Nannf.) L. T. ...

AI Technical Summary

Problems solved by technology

The traditional identification method is to identify the "shape", "color", "gas" and "taste" of medicinal materials or decoction pieces as the basic elements, which has high requirements for the technical level, practical ability and professional skills of the identifyrs. Rich experience and keen judgment ability are required. Due to the uneven level of inspectors, the accuracy, repeatability and consistency of conclusions are not high, and misjudgments often occur

Similarly, for the phenomenon of artificial adulteration and fraud, the physical and chemical identification methods included in the national standards cannot meet the needs of the authenticity and quality identification of traditional Chinese medicine decoction pieces

It is necessary to learn from modern science and technology and testing equipment, and according to the specific types of decoction pieces that are adulterated in the market, purposefully and targetedly build specific quantitative detection and testing methods, or conduct alternative research on the identification characteristics of existing identification methods, which seriously restricts Quality Inspection and Quality Judgment of Chinese Herbal Pieces
