| 中文摘要： | 目的：为山药药材规格等级划分提供参考。方法：采用德尔菲法，选择与山药药材流通和临床应用等研究相关的17名专家就18份药材样品进行两轮咨询，对山药药材感官评价指标的重要性进行筛选，对整体满意度进行评价，并初步确定山药药材的规格等级。结果：每轮咨询均发放问卷17份，回收有效问卷17份，有效回收率均为100％。经统计学分析，受访专家权威程度系数平均值为0.77±0.07，个人评审重现率平均值为（91.18±7.64）％，两轮咨询群体评审重现率平均值分别为（66.67±13.50）％和（65.97±14.01）％；工作年限、从业背景和教育背景对受访专家群体评审重现率的影响是综合发挥作用的。受访专家对药材样品外观形状和断面特征两个感官评价指标的重要性评分满分比均＞80％，平均值均＞0.8；铁棍山药样品两轮整体满意度评分满分比和平均值均较高。结论：凭借感官经验评价中药材规格等级具有一定的准确性和科学性。山药药材最主要的感官评价指标为外观形状和断面特征；规格初步分为铁棍山药和非铁棍山药。铁棍山药等级由高到低分为：河南沙土铁棍山药、山东沙土铁棍山药、河南垆土铁棍山药；非铁棍山药等级由高到低分为：河南怀山药、河北小白嘴山药、河北麻山药和山西长山药。 |
| 英文摘要： | OBJECTIVE： To provide reference for the classification of the specification grade of Dioscorea opposite. METHODS： Using the Delphi method， 17 experts， who were associated with the study of the distribution and clinical application of D. opposite， were selected to conduct two rounds of consultation on 18 samples of medicinal herbs. The importance of the sensory evaluation indexes of D. opposite was screened and the overall satisfaction was evaluated. The specification grade of D. opposite was determined preliminarily. RESULTS： Totally 17 questionnaires were issued for each round of consultation， and 17 were recovered with recovery rate of 100％. According to statistical analysis， the average value of expert’s authority coefficient was 0.77±0.07， and average recurrence rate of individual review was （91.18±7.64）％. The average recurrence rates of group review in two rounds of consultation were （66.67±13.50）％ and （65.97±14.01）％ . The influence of working life， business background and educational background on recurrence rates of group review for interviewed experts was comprehensive. The full score ratio of appearance and cross-sectional characteristics importance was more than 80％， and the average value was more than 0.8. The full score ratio and average value of iron yam were higher. CONCLUSIONS： It is accurate and scientific to evaluate the specification grade of Chinese medicinal herbs with sensory experience. The most important evaluation indicators of D. opposite were the appearance， shape and cross-sectional characteristics. And it is divided into iron yam and non-iron yam preliminarily. The iron yam grade in descending order： Henan sandy iron yam， Shandong sandy iron yam， Henan loquat iron yam. The non-iron yam grade in descending order： Henan Huaiqingfu D. opposite， Hebei Xiaobaizui D. opposite， Hebei Ma D. opposite and Shanxi Chang D. opposite. |
