太子参商品规格等级标准研究

目的:为规范太子参商品市场秩序,实现中药材产业发展的规范化、科学化,制定太子参商品规格等级标准。方法:对市场上收集到的不同产地、不同等级太子参药材的9个外观性状量化指标进行测量,并结合内在质量的化学成分指标验证商品药材等级的科学性,在此基础上运用SPSS软件进行相关性分析、主成分分析和聚类分析,结合生产和市场实际运用,制定出太子参商品规格等级标准。结果:通过主成分和聚类分析,结合生产实际筛选出上中部直径、单个重量、50 g块根数3个指标,并划分大选、中选、小选、大统、小统5个等级。相关性分析认为,块根长度不宜作为太子参药材商品分级指标,多糖含量的高低与太子参商品等级有关系。结论:以上中部直径、单个质量、50 g块根数作为太子参药材商品规格等级标准划分的外观量化指标,以太子参多糖含量作为药材内在质量评价指标。制定的太子参商品规格分为5级,各等级与市场上太子参药材等级现状及其内在品质相一致,可作为市场商品规格等级的划分依据。

Classification study on commodity specification and grade standard of Pseudostellariae Radix

Objective: To study the commodity specification and grade standard of Pseudostellaria Radix, for standardizing market order and achieving industrialization, standardization and modernization of Pseudostellariae Radix. Method: The different areas and grade medicinal materials of Pseudostellariae Radix were respectively measured in quantitative characteristics of appearance, and the present grade classification of Pseudostellaria Radix was scientifically verified by the content of polysaccharide. Then the determination data were evaluated by spss correlation analysis, principal component analysis and cluster analysis. So combining with the actual production, the commodity grade standard of Pseudostellariae Radix was formulated. Result: Correlation analysis indicated that the present grade classification of Pseudostellaria Radix was reasonable, and the more the grade of Pseudostellariae Radix was high, the more the content of polysaccharide was high. Meanwhile, length as a classification index was not suitable for the commodity grade standard of Pseudostellariae Radix. Using principal component analysis and cluster analysis, combining actual production, the thickest diameter, weight of single root tuber and the number of 50 g root tuber were filtrated and the grade was divided into 5 ranks: big, middle, small selected goods, big ungraded goods and small ungraded goods. Conclusion: the commodity specification and grade standard of Pseudostellariae Radix that mainly included the thickest diameter, weight of single root tuber and the number of 50 g root tuber was formulated. the standard was divided into 5 grade. Each grade was not only consistent with the present situation of medicinal materials market, it could also reflected the intrinsic quality of Pseudostellariae Radix. In conclusion, the standard could be used as a classification basis to the commodity specification and grade.
