芝麻木脂素的抗氧化研究

Study on the Antioxidation Effect of Sesame Lignans

从芝麻混合油中制备的木脂素和从芝麻饼中制备的木脂素对[DPPH·]自由基的清除率与木脂素甲醇溶液体积用量的线性回归方程分别为Y=63.88X+3.026和Y=327.24X+8.928,相关系数R分别为0.9986和0.9970,计算得IC50值分别为0.74 mL,0.13 mL,前者大于后者,说明从芝麻混合油中制备的芝麻木脂素对[DPPH·]自由基的清除能力比从芝麻饼中制备的芝麻木脂素的能力弱。通过Rancimat法测定芝麻木脂素对大豆油的抗氧化性能良好,并与VE具有协同作用。

Linear regression equation of free radical clearance-sesame lignans which we obtained in the mix sesame oil and sesame cakes volume was Y=63.88X+3.026 and Y=327.24X+8.928,with R being 0.9986 and 0.9970 respectively.IC50 of free radicals DPPH were 0.74 mL、0.13 mL,respectively.That means clearance free radical ability of lignans in the mix sesame oil was poorer than in sesame cakes.The antioxidant properties of sesame lignans were determined by Rancimat,the antioxidation ability of sesame lignans is good,which has synergistic action with VE.
