为了建立天麻生化指纹图谱最佳测定方法,利用指纹图谱对天麻进行科学分类和评价,运用优化的高效液相色谱方法测定了9种天麻的生化指纹图谱及其天麻素含量；运用分析软件计算了它们的生化指纹图谱的相似系数；运用聚类分析方法和相似系数对天麻进行系统分类；根据天麻素含量和色谱峰面积对天麻品质进行综合评价,结果表明:9种天麻被分为3个不同的类群,第Ⅰ类天麻含有较多天麻素(平均含量5.67 mg·g-1),品质最好,其中来自湖北宜昌和湖南石门的天麻样本的天麻素含量最高,分别高达7.52 mg· g-1和7.26 mg·g-1.湖北宜昌和湖南石门之间的山区可能是天麻适宜种植地区.天麻的天麻素含量与生化指纹图谱和...

To establish the optimal method for determining biochemical fingerprints of Gastrodia tuber and conduct a scientific classification and assessment on Gastrodia tuber with biochemical fingerprints,we employed the optimized high performance liquid chromatography method to determine the biobiochemical fingerprints and gastrodin content of nine Gastrodia tuber populations,used analytic software to calculate similarity coefficients of their biochemical fingerprints, conducted systemic classification on Gastrodia tuber by using the similarity co- eff...
