为探究天麻(Gastrodia elata Bl.)质量评价的重要指标,本研究测定了27份陕西省汉中市天麻样品的外观性状、气味、颜色、含水量、浸出物和主要有效成分的含量,采用主成分分析(Principal Component Analysis,PCA)法确定其主要成分,结合熵...为探究天麻(Gastrodia elata Bl.)质量评价的重要指标,本研究测定了27份陕西省汉中市天麻样品的外观性状、气味、颜色、含水量、浸出物和主要有效成分的含量,采用主成分分析(Principal Component Analysis,PCA)法确定其主要成分,结合熵权TOPSIS(Technique for Order Preference by Similarity to an Ideal Solution)法得出天麻质量评价体系中各评价指标的权重,并对天麻质量进行综合评价。结果表明汉中市宁强县、略阳县、勉县产出的天麻在块茎粗、螺环纹数、鲜重、干重、颜色明亮度和总色度值上有一定差异;水分、浸出物含量以略阳县最高;天麻素与对羟基苯甲醇总含量以宁强县最高,勉县所产天麻的天麻素与对羟基苯甲醇含量接近,其成分含量比例与其他县差异显著;此外,宁强县所产天麻的巴利森苷类成分含量最高。PCA熵权TOPSIS法评价结果显示,宁强县、略阳县天麻排名靠前,各项指标中颜色因子、巴利森苷类因子、气味因子权重较大,因此天麻质量评价应注重颜色、气味以及巴利森苷类成分含量。展开更多
