Problems solved by technology

The medicinal part of Salvia miltiorrhiza is the root, which has a certain enrichment effect on trace elements and rare earth elements in the soil. Therefore, the content of trace elements and rare earth elements in Danshen from different origins is small, and it is difficult to directly use the contents of trace elements and rare earth elements. Trace the origin of Salvia miltiorrhiza

Abstract

The invention discloses a method for carrying out producing area tracing on radix salviae miltiorrhizae by combining determination of the content of microelements and rare-earth elements with multivariable statistical analysis. According to the method disclosed by the invention, difference analysis is carried out on all elements of all samples by adopting one-way analysis of variance. When p is less than 0.05, element data of different producing areas has obvious difference. Main component analysis is used for data dimension reduction analysis and linear judgment analysis is used for estimating whether radix salviae miltiorrhizae medicinal materials from the different producing areas have remarkable difference or not. The invention provides the method for carrying out producing area tracing on the radix salviae miltiorrhizae; and the method has the advantages of sensitivity, rapidness and high judgment accuracy.

Description

technical field [0001] The invention specifically relates to a method for tracing the origin of salvia miltiorrhiza by using the content determination of trace elements and rare earth elements combined with multivariate statistical analysis. Background technique [0002] Genuine medicinal materials are famous and authentic medicinal materials produced in regions with specific natural conditions and ecological environment, and are high-quality Chinese medicinal materials produced and recognized in long-term and repeated clinical practice of traditional Chinese medicine. In recent years, with the increase in the demand for traditional Chinese medicine, the phenomenon of off-site planting of authentic medicinal materials is common, resulting in a significant decline in the quality of traditional Chinese medicine. The origin traceability of traditional Chinese medicine is of great significance to maintaining the market order of Chinese medicinal materials, ensuring the quality o...
