栀子药材商品规格等级标准研究

采集来自全国各地不同商品等级野生和栽培的栀子样品,以D65光源、图像信息收集软件提取果皮颜色的色泽数据,利用数显游标卡尺对栀子饱满度信息进行量化,用高效液相色谱法测定栀子6种成分的含量,利用两步聚类分析和对应分析等统计方法对10个指标进行了分类比较,确定各传统鉴别主征的显著性和重要程度,建立栀子药材传统商品规格分类与果皮颜色的多重对应关系,探索果皮颜色与活性成分指标的相关性,为栀子药材商品规格等级的合理划分提供依据。经过分析,药材可分为2类且有显著的区分意义,果皮颜色传统判别主征的重要性大于饱满度,对栀子的一、二等品能进行较为准确的区分。该研究补充并重建了栀子商品规格等级的划分标准,同时制定了栀子等级快速评判的方案,为栀子药材品质的综合评价提供了新途径和新思路。

Study on commercial specification of Gardenia jasminoides

Collecting different commodity grade Gardenia jasminoides of wild and cultivated varieties all over the country, obtaining color information from each batch of G. jasminoides by the standard D65 light source and image acquisition system, quantifing the gardenia plumpness information by the digital display vernier caliper, determinating 6 kinds of effective components of G. jasminoides by HPLC, classifing from ten indicators by two step clustering analysis and correspondence analysis method of statistics, clearing the importance of the traditional identification indexes, establishing multiple corresponding relation between the skin color and commercial specification of G. jasminoides,exploring the correlation of the skin color and chemical composition, to provide the reference for the reasonable division of commercial specifications and grades of G. jasminoides. Medicine is divided into two classes and has obvious distinguish meaning, The importance of the skin color is greater than the plumpness in traditional identification characteristics, it can accurately distinguish the specifications of G. jasminoides. We improve and rebuild the standard of commodity specifications and grades of Gardenia jasminoides Ellis and establish the rapid evaluation method by the study, it provide a new way and idea for the comprehensive evaluation of G. jasminoides quality.
