半夏商品规格等级标准及质量评价研究
|
摘要
以5个药材市场、2个产地收集的42份半夏为研究对象,在本草考证与市场调查基础上,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等方法,选定分级指标,结合生产实际,制定半夏商品规格等级标准;分析不同等级半夏内在指标(水分、总灰分、浸出物及鸟苷)间的差异及外观性状与内在指标的相关性。本草考证与市场调研结果显示,半夏以个大、色白、质坚实者为佳;描述性分析和方差分析显示,半夏外观性状在每粒重及500 g粒数上差异较明显,结合生产实际及2015年版《中国药典》规定,筛选出长、每粒重、500 g粒数作为半夏的分级指标,将半夏分为大选、小选、统货3个规格等级;相关性分析显示,半夏外观性状与内在品质指标间无显著相关性;多重比较显示,除总灰分和浸出物外,各等级间的内在指标含量无显著差异。该文建立了以长、每粒重、500 g粒数为指标的半夏商品规格等级标准,为半夏市场商品规格等级的划分提供依据。
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.
