The distribution of lignans within common millet, common buckwheat, tartary buckwheat, and amaranth plants, as well as any differences of their contents within their different varieties and samples from different growing seasons, were determined by LC-MS analyses. Roots were the plant part highest in the total amount of lignans in common buckwheat, tartary buckwheat, and common millet. Which is in contrast to amaranth, where the stems were the richest part. The roots of tartary buckwheat contained five times more total lignans than amaranth stems or common buckwheat roots. The dominant lignan in tartary buckwheat roots was 7-hydroxymatairesinol, in amaranth stems and the roots of common buckwheat it was syringaresinol, and in the roots of common millet it was 7'- oxomatairesinol. The lignin content in the roots, stems, and eventually leaves were significantly influenced by the growing season. In the case of common millet and common buckwheat, differences in lignan levels due to varietal differences were confirmed.
