The presence of plant lignans in 14 different soy-based health supplements is reported here for the first time together with the analysis of the isoflavone content, for which these products are commercialized. Six plant lignans, i.e., secoisolariciresinol, matairesinol, syringaresinol, lariciresinol, isolariciresinol, and pinoresinol, have been identified and quantified by gas chromatography-mass spectrometry, and a positive correlation has been found between the levels of plant lignans and the levels of isoflavones in the different products. Additional quantification of plant lignans and isoflavones in soybeans has been carried out, and results are provided to allow the comparison of the average levels in soybeans and soy-based supplements.
本文首次报道了14种不同大豆基健康补充剂中植物木脂素的存在情况，并对这些产品商业化所依据的异黄酮含量进行了分析。通过气相色谱-质谱联用仪已鉴定并定量了六种植物木脂素，即开环异落叶松脂素、罗汉松脂素、丁香树脂醇、落叶松脂素、异落叶松脂素和松脂醇，并且发现不同产品中植物木脂素水平与异黄酮水平之间存在正相关。还对大豆中的植物木脂素和异黄酮进行了额外定量，并给出结果以便比较大豆及大豆基补充剂中的平均含量。
