在芝麻油的工业漂白过程中，产生了高浓度的具有较强抗氧化活性的木脂素类化合物P3。P3（命名为芝麻胺醇）与先前从芝麻种子的丙酮提取物中分离的次要成分相同。结果表明，未加工芝麻油中的芝麻林是芝麻酚的来源，芝麻酚的形成通过添加芝麻林的玉米油的模型实验得到证实。芝麻胺酚没有那么大的去除漂白后的漂白过程中，芝麻，它被证明是在约的浓度。100 mg/100 g，在商业精炼未烘焙的籽油中。芝麻胺醇的抗氧化活性大致等于芝麻精和γ-亚麻酸的抗氧化活性。用硫氰酸盐法测定生育酚。因此，芝麻油的抗氧化活性主要来自于芝麻酚。
A lignan compound, P3, having strong antioxidative activity was found to be formed in high concentration during the industrial bleaching process of unroasted sesame seed oil. P3 (named sesaminol) was identical to a minor constituent previously isolated from acetone extract of sesame seed. It was shown that sesamolin in unprocessed sesame oil is the source of sesaminol, and the formation of sesaminol was confirmed by the model experiment with corn oil to which sesamolin had been added. Sesaminol was not so greatly removed by the deodorization process that follows bleaching as was sesamol, and it was shown to be at a concentration of ca. 100 mg/100g in commercial refined unroasted seed oil. The antioxidative activity of sesaminol was roughly equal to those of sesamol and .gamma.-tocopherol by the thiocyanate method. Therefore, it seems that the antioxidative activity of refined unroasted seed oil is mainly attributed to sesaminol.
