AI Technical Summary
Technical Problem
[0003]目前，色谱分析、近红外光谱分析及电子感官分析等技术常用于鉴别来源不同的干姜药材，尽管这些方法均能在一定程度实现干姜药材的产地识别，但仍存在准确性较低、特异性较差，耗时等不足
Benefits of technology
[0025] The present application first proposes to use stable isotopes combined with multiple elements for the origin traceability of dried ginger medicinal materials, and stable isotopes and element fingerprint information can greatly reflect the characteristic regional information of dried ginger from different origins. This method has the advantages of high detection precision, strong sensitivity and reliable method, avoids the uncertainty based on subjective recognition and inherent labels of dried ginger, and has good popularization and application value.

Abstract
The application discloses a kind of dry ginger medicinal materials origin traceability method based on multiple type weight elements, and specifically relates to the field of traditional Chinese medicinal materials origin traceability.The method determines the stable isotope ratio and the multiple element content of dry ginger in different producing areas, uses chemometrics means, constructs the dry ginger medicinal materials origin traceability dataset and origin discrimination model based on stable isotope ratio combined with multiple element content, and selects the multiple type weight elements affecting the origin discrimination as the characteristic index of dry ginger origin traceability, to realize the accurate identification of genuine medicinal material Sichuan dry ginger.The method for realizing the dry ginger medicinal materials origin traceability based on stable isotope and multiple elements has the advantages of simple operation, good stability, high discrimination accuracy, etc., and can provide a new idea for the origin identification of genuine medicinal material Sichuan dry ginger.
