Biotransformation of lignans and neolignans

Biotransformation of plants' secondary compounds by the variety of organism sometimes afford novel and/or useful compounds. The ability of organism me tabolizing those natural products and the metabolic fate of those in nature can also be revealed by this investigation. Lignans and neolignans are wel l known plants' secondary compounds which are widely distributed in terrest rial plants, and have attracted much attention due to the varied biological activities. This review summarizes recent research in to field of biotrans formation of lignans and neolignans.
