Hypouricemic effect of flaccidoside II in rodents.

To investigate the effect of flaccidoside II on the serum uric acid levels in hyperuricemic rodents. Both mice and rats were injected intraperitoneally with potassium oxonate to induce hyperuricemia. Different dosages of flaccidoside II were orally administrated to hyperuricemic and normal rodents for 7 days, respectively.

Protective effect of homonojirimycin from Commelina communis (dayflower) on influenza virus infection in mice.

The effects of homonojirimycin (HNJ), one of alkaloids from Commelina communis L., on protection against influenza virus infection in mice were investigated. HNJ was found to improve the survival rate, prolong the mean survival time and reduce virus yields in lungs on days 4 and 6 post-infection (p.
