The study aims at investigating the grade standard and the quality characteristic of Pinelliae Rhizoma for commodity specification, which provides the reference for its grade standard formulation. 42 Pinelliae Rhizoma simples were collected from 5 medicinal materials markets and 2 producing areas. Based on the previous herbalogical study and market investigation, we combined with the data analysis to select the grading indicators using SPSS software for descriptive statistical analysis, analysis of variance, K-cluster analysis and correlation analysis. According to the actual production condition, we developed the grading standards of Pinelliae Rhizoma. Moreover, we compared the internal indicators(water, total ash, leachate and guanosine) of Pinelliae Rhizoma at various grade levels, and analyzed the correlation between appearance traits and internal indicators. The herbalogical study and market research found that the Pinelliae Rhizoma was better in large, solid and white. The results from descriptive and variance analysis showed that the appearance of Pinelliae Rhizoma was significantly different in weight per grain and grain number of 500 g. Referring to the 2015 Chinese Pharmacopoeia and the production practice, we use the length, weight per grain and grain number of 500 g as the classification index of Pinelliae Rhizoma. The results from correlation analysis showed that there was no significant correlation between the appearance of Pinelliae Rhizoma and the intrinsic quality index. In addition, we found there was no significant difference in the content of the intrinsic index except for the total ash and the extract. The current study established the classification index of the product specification and grade standard of Pinelliae Rhizoma with length, weight per grain and grain number of 500 g as the index, which can provide the basis for the classification of the product specification and grade of Pinelliae Rhizoma market.
本研究旨在探讨半夏商品规格的等级标准及质量特征，为其等级标准制定提供参考。从5个药材市场和2个产地收集了42份半夏样品。基于以往的本草学研究和市场调研，结合数据分析，运用SPSS软件进行描述性统计分析、方差分析、K聚类分析和相关性分析，筛选分级指标。根据实际生产情况，制定半夏的分级标准。此外，比较了不同等级半夏的内在指标（水分、总灰分、浸出物和鸟苷），并分析了外观性状与内在指标之间的相关性。本草学研究和市场调研发现，半夏以个大、坚实、色白为佳。描述性分析和方差分析结果表明，半夏的外观在单粒重量和500 g粒数上有显著差异。参照2015年《中国药典》及生产实际，以长度、单粒重量和500 g粒数作为半夏的分类指标。相关性分析结果表明，半夏外观与内在质量指标之间无显著相关性。此外，发现除总灰分和浸出物外，内在指标含量无显著差异。本研究建立了以长度、单粒重量和500 g粒数为指标的半夏商品规格分类指标和等级标准，可为半夏市场商品规格和等级分类提供依据。
