Solani. The extract was further separated into two parts and one part separated by ethyl acetate while the other was separated by petroleum ether. Based on the inhibition experiment against R. solani, ethly acetate extract has a rather strong effect on R. solani with 89.70% inhibition rate and 15.52 mgmL^(-1) EC 50.The effect of petroleum ether extract on R. solani is relatively weak. The former was again divided into five parts in silica gel column, of which the second part significantly inhibits R. solani. During the periods of 24 and 48 hrs, the inhibition rate of the second part on R. solan is respectively 89.58% and 80.36%.

AIM: To isolate bioactive secondary metabolites from the fruits of Schisandra rebriflora Rehd. et. Wils and study their effects on HIV-1 infectivity. METHODS: Inhibition of syncytia formation, HIV-1 reverse transcriptase and protease, protection of HIV-1 infected cells, level of HIV-1 p24 antigen,blockage of fusion were detected. RESULTS: A lignan compound, named rubrifloralignan A, was first isolated as a natural product with modest inhibition effects on syncytium formation and HIV- 1 replication and could protect HIV-1 infected cells with weak inhibition effects on fusion and RT, but it showed no effects on the replication of HIV-1 chronic H9 and PR. CONCLUSION: Rubrifloralignan A is an efficient anti-HIV-1 product with effect on early stage of HIV-1 replication.

Results: Tyroserleutide can significantly increase the life span of H22 tumor-bearing mice by 50-70% in dosages of 20ug/kg/d-80ug/kg/d,specially the high dosage of 80ug/ml can significantly increase the life span by 69.24%; Tyroserleutide can inhibit the growth of transplanted hepatocellular tumor BEL-7402 in nude mice,the rate of tumor inhibition was25-50% in dosages of 40-320ug/ml ,the inhibition rate of 160ng/ml was 44.03%; Tyroserleutide could inhibit the growth of H22 and BEL-7402 tumor in a dose-dependent manner. Simultaneously, tumoricidal activity of tyroserleutide against BEL-7402 cell line in vitro was observed hinger when compared with the control group(P.05).The inhibition effect of 72hrs was higher than 24hrs,48hrs,96hrs.And specially the high dosage of 160ug/ml can significantly inhibit growth of tumor cell by 19.36%. Tyroserleutide can activated PEM and marked enhance cytotoxicity andphagocytosis functions in vitro and in vivo. The OD values of cytotoxicity were observed hinger when compared with the control group(P.05).The cytotoxicity of macrophages activated by tyroserleutide against BEL-7402 and B16-F10 was 35.58%,61.2% in vitro and21.39%,47.63% in vivo. The cytotoxicity rate of nude mice PEM was 32.86%,73.07% in vivo. Furthermore, tyroserleutide alone could stimulated the production of IL-1B TNF- a and NO by M . Tyroserleutide and LPS could synergistically activated M producing more cytotoxicity effectors. Conclusion: Tyroserleutide had inhibition functions against hepatoma carcinoma .Its possible mechanisms were related to the affect that Tyroserleutide could inhibit tumor cell directively and induce tumor cells apoptosis or death effectively.
