摘　　要：目的:研究不同亚麻籽品种中生物活性物质含量的差异。方法:以12个亚麻籽品种为研究对象,测定亚麻籽中8种生物活性物质含量,并对其进行主成分分析,同时对亚麻籽品种进行聚类分析。结果:品种对亚麻籽生物活性物质的影响顺序为木酚素>总氰化物>黄酮>植物甾醇>总酚酸>生育酸>FRAP值>DPPH值。主成分分析可提取出3个主成分,累计贡献率达82.925%,第一主成分主要由黄酮和FRAP值决定,第二主成分主要由木酚素和生育酚决定,第三主成分主要由总氰化物和总酚酸决定。聚类分析将12个亚麻籽品种划分为三大类,其综合评价值依次降低,第I类包括坝亚11、宁亚17、坝亚9、陇亚8和轮选2;第II类包括陇亚10、宁亚16和晋亚7;第Ⅲ类包括轮选1、晋亚8、伊亚3和伊亚4。结论:综合评分坝亚11最高,具有较高的营养保健价值。Objective: This study aimed to investigate the difference of bioactivators from different flaxseed. Methods: 12 flaxseed varieties were used as study objectives, 8 kinds of bioactivators from different varieties of flaxseed were measured and analyzed by principal component and clustering. Results: The order of effect of flaxseed varieties on bioactive substances was as follows: lignan>total cyanide>flavone>phytosterol>total phenolic acid>tocopheronic acid>FRAP value>DPPH value. 3 principal components were extracted by principal component analysis and their accumulative contribution rate reach to 82.925%. The first, second and third principal component were mainly determined by flavone and FRAP values, lignan and tocopheronic acid, total cyanide and total phenolic acid, respectively. 12 flaxseed varieties were divided into three groups by clustering analysis, and their comprehensive assessment value reduced successively. Group I include Baya11, Ningya17, Baya9, Longya8 and Lunxuan2, Group II include Longya10, Ningya16 and Ningya16 and Jinya7, and Group III include Lunxuan1, Jinya8, Yiya3 and Yiya4. Conclusion: Comprehensive score of Baya11 is the highest, and it has higher nutritional value.
