[Recent advances in the study of natural homoisoflavonoids].

Homoisoflavonoid is a special type in flavonoids. There are more than 110 homoisoflavonoid compounds isolated from natural materials. Homoisoflavonoid compounds show many bioactivities on anti-inflammatory, estrogenicy, antiestrogenic, anticancer and angioprotective etc. This paper summarized the plant sources, structural types spectrocopy features and the biology activities of homoisoflavonoids.
