There are 65 species of Chinese herbs with confirmed anti-HBV activityd, in which 16 probable active constituents are pointed out. They are arene, ketone derivatives, alicyclic carboxylic acid, aromatic carboxylic acid, ester, lactone, cyanide derivatives, heterocycle derivatives, carotenoids, anthraquinones, flavonoids, vegetable tannin, alkaloid, terpenoids, steroids and protein. Among them, the complexes of flavonoids, terpenoids, steroids and alkaloids are more abundant.
