(+)-Secoisolariciresinol（Cat No.:I044827）is a plant-derived lignan predominantly found in flaxseed, whole grains, and various fruits and vegetables. Structurally, it features a dibenzylbutane skeleton with multiple hydroxyl groups, contributing to its antioxidant properties. In the human body, it is converted by gut microbiota into enterolignans such as enterodiol and enterolactone, which exhibit weak estrogenic activity. (+)-Secoisolariciresinol has been studied for its potential health benefits, including cardiovascular protection, hormone-related cancer risk reduction, and anti-inflammatory effects. Its presence in functional foods highlights its value in promoting long-term health and disease prevention.
