DescriptionDaidzein, also known as daidzeol or isoaurostatin, belongs to the class of organic compounds known as isoflavones. These are polycyclic compounds containing a 2-isoflavene skeleton which bears a ketone group at the C4 carbon atom. Thus, daidzein is considered to be a flavonoid. Daidzein is a bitter tasting compound. Daidzein is found, on average, in the highest concentration within a few different foods, such as other snack food, soy milk, and soy beans (Glycine max) and in a lower concentration in sauce, soup, and cake. Daidzein has also been detected, but not quantified in, several different foods, such as garden cresses (Lepidium sativum), star anises (Illicium verum), mamey sapotes (Pouteria sapota), wakames (Undaria pinnatifida), and cornmints (Mentha arvensis). This could make daidzein a potential biomarker for the consumption of these foods. Based on a literature review a significant number of articles have been published on Daidzein.
