目的 完善桔梗药材质量评价方法，研究3年生桔梗药材不同采收期下药材质量差异，确定桔梗药材最佳采收期。方法 以桔梗药材浸出物、灰分、水分、折干率以及所含6种皂苷类活性成分含量作为质量评价的检测指标，借助数理统计学方法，对不同采收期桔梗药材之间的差异进行表征。并结合熵权法、灰色关联度分析、TOPSIS法3种数学模型对桔梗药材质量评价指标进行统计分析，获得不同采收期桔梗药材质量排名信息。结果 采收期是影响桔梗药材质量差异的重要因素，不同采收期下3年生桔梗药材质量评价指标之间差异明显。所增加的多指标检测完善了桔梗质量评价体系，增强了药材的"性-效"联系。结合质量评价模型结果显示，3年生桔梗以10月21日(霜降)前后采收的桔梗药材综合指数得分最高。结论 为保证桔梗药材质量，结合药材外观性状特征与药材物质基础综合考虑，确定以"霜降"节气前后作为3年生桔梗的最佳采收期。
Study on the Optimal Harvesting Period of Platycodonis Radix by Grey Correlation Method and TOPSIS Method Based on Entropy Weight Method
OBJECTIVE To improve the quality evaluation method of Platycodonis Radix,to study the differences in the quality of three-years-old Platycodonis Radix under different harvesting periods,and to determine the optimal harvesting period of Platycodonis Radix.METHODS The leachate,ash,moisture,refractive index and the content of six saponins were used as the quality evaluation indexes.The differences between the herbs of Platycodonis Radix at different harvesting periods were characterized with the help of mathematical and statistical methods.And link the entropy weight method,gray correlation analysis and TOPSIS method were combined to obtain the statistical analysis of the relevant indexes and the quality ranking information of the herbs in different harvesting periods.RESULTS There were significant differences between the quality evaluation indexes of three-years-old Platycodonis Radix at different harvesting periods.The added multi-indicator testing had improved the quality evaluation system of Platycodonis Radix and enhanced the"Drug properties-Effectiveness"linkage of the herbs.And the results of the comprehensive quality evaluation model showed that the herbs harvested around October 21(Frost's Descent)were ranked best in terms of comprehensive index.CONCLUSION In order to ensure the quality of Platycodonis Radix,the best harvesting period for three-years-old Platycodonis Radix is determined around the"Frost's Descent"season,taking into account the characteristics of the herbs'appearance and the material basis of herbs.
