采用化学计量学方法，比较不同品种和不同产地亚麻籽的体外抗氧化活性和生物活性成分，进一步探索构建我国亚麻籽内源抗氧化系统的特异性成分。测定了32个亚麻籽品种的α-亚麻酸（35.83-58.91%）、木脂素（11.37-33.31mg/g）、总酚酸（109.93-246.88mg/100 g）和植物甾醇（56.52-125.12mg/g）的含量差异。同时，体外抗氧化活性分别为32.56 - 46.22 mg TE/100 g，0.58 - 1.08 mg TE/g和14.22 - 36.14 mmol TE/g，通过2，2 '-二苯基-1-苦肼基自由基（DPPH），铁还原抗氧化能力（FRAP）和2，2-连氮双-（3-乙基苯并噻唑啉6-磺酸）（ABTS）测定。抗氧化活性与游离胡萝卜酸、对香豆酸葡萄糖苷和开环异落叶松树脂酚二葡萄糖苷（SDG）含量呈显著正相关（p
The present study aimed to use a chemometric study to compare the in-vitro antioxidant activities and bioactive compounds of flaxseed based on the variety and geographical origins, and further explore the specific components constructed the endogenous antioxidant system of flaxseed in China. The differential contents of -linolenic acid (35.83-58.91%), lignans (11.37-33.31mg/g), total phenolic acids (109.93-246.88mg/100 g) and phytosterols (56.52-125.12mg/g) of 32 flaxseed varieties were observed. Concomitantly, the in-vitro antioxidant activities varied from 32.56 to 46.22mg TE/100 g, 0.58 to 1.08mg TE/g, and 14.22 to 36.14mmol TE/g as determined by the 2,2'-diphenyl-1-picrylhydrazyl radical (DPPH), ferric reducing antioxidant power (FRAP) and 2,2-azinobis-(3-ethylbenzthiazoline 6-sulfonic acid) (ABTS) assays, respectively. Significant correlations were found between the antioxidant activities and contents of free syringic acid, p-coumaric acid glucoside and secoisolariciresinol diglucoside (SDG) (p
