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. |
