Condensation of resorcinol or phloroglucinol with sodium hydrogen malate in the presence of catalytic sulfuric acid leads to the synthesis of natural bioactive umbelliferone and daphnetin under microwave irradiation.

在适量硫酸的存在下，用微波辐射合成了天然活性香豆素伞形花内酯和瑞香内酯。

The inhibition level of the COX activity by daphnetin after being treated for 2, 4, 8 and 12 h were 0.6%, 73% and 80% respectively and the inhibition level by daphnetin at different concentrations （0.1, 1, 100 and lmmol/L） for 6h was 3%, 31%, 53% and 84%, respectively.

在体外瑞香素可显著降低恶性疟原虫的细胞色素C氧化酶及核糖核酸还原酶活性。

The formation and characters of the vesicles were demonstrated by negative-staining TEM and dynamic light scattering. Using the vesicles as the delivery of daphnetin, we carried out the research on the effect of formation and temperature upon entrapment efficiency. Research had also been carried out upon the release circumstance of daphnetin contained in the vesicles in simulated gastric and intestinal fluid.
