为探究不同产地兰州百合间的品质差异。对13个产地兰州百合样品的感官指标进行打分,测定可溶性固形物、水分、蔗糖等化学成分指标的含量,再通过Pearson相关性分析、主成分分析和正交-偏最小二乘法判别分析对不同产地兰州百合的感官评价及化学成分指标数据进行处理。结果表明,七里河区上岭村及永靖县关山乡样品总体喜欢度评分最高；不同产地兰州百合的化学成分含量间均存在一定差异；因子分析筛选并验证了氨基酸、总皂苷、多糖、水分、可溶性固形物和蔗糖等成分在不同产地的兰州百合中差异显著；兰州百合感官指标与化学指标之间存在一定相关性(P<0.05)；OPLS-DA结果可以区分不同产地兰州百合样品；聚类分析结果表明不同产地的兰州百合存在差异性；主成分综合评价结果得出临洮县上康家湾村所产兰州百合品质最好。该研究结果初步揭示了兰州百合感官指标与和化学成分指标的关系,能够为兰州百合的种植推广和产品开发提供参考依据。

In order to establish a "sensory-chemical-comprehensive" evaluation system, the quality difference of Lilium davidii var. willmottiae (E. H. Wilson) Raffill from different producing areas was investigated. The sensory indexes of L. davidii var. willmottiae samples from 13 producing areas were scored to determine the contents of soluble solid, water, sucrose and other chemical components. Then, the sensory evaluation and chemical composition indexes data of L. davidii var. willmottiae from different producing areas were processed by Pearson correlation analysis, principal component analysis and orthogonal partial least square discriminant analysis. The results showed that the samples from Shangling Village in Qilihe District and Guanshan Township in Yongjing County had the highest overall liking scores. There were some differences in the chemical constituents of L. davidii var. willmottiae from different producing areas. Factor analysis screened and verified that amino acids, total saponins, polysaccharides, water, soluble solids and sucrose were significantly different in L. davidii var. willmottiae from different producing areas. There was a certain correlation between sensory indexes and chemical indexes of L. davidii var. willmottiae (P<0.05). The results of OPLS-DA can distinguish L. davidii var. willmottiae samples from different origin. The results of cluster analysis showed that there were differences in L. davidii var. willmottiae of different origin. The comprehensive evaluation results of principal components showed that L. davidii var. willmottiae produced in Shangkang Jiawan village, Lintao County had the best quality. The results of this study preliminarily revealed the relationship between sensory index and chemical composition index of L. davidii var. willmottiae, and could provide reference for planting promotion and product development of L. davidii var. willmottiae.
