In order to enhance the medical effects of Ganoderma lucidum submergedly cultured broth, the aqueous extract of Radix sophorae flavescentis, a traditional Chinese medicine, was added into the cultivation medium of G. lucidum. The organic acids were extracted with ethanol, chloroform, 5% NaHCO3 and chloroform in turn from the cultured broth of Ganoderma lucidum which cultivation medium contained Radix sophorae flavescentis extract. Six new components were separated from the organic acids with preparative HPLC. Their inhibitory effects on HBsAg and HBeAg secretion of HBV DNA transferred HepG2 cell (2.2.15 cell) were investigated. The results indicate that 3 components of the six have significant inhibitory effects on the antigen secretion.
