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.

Aphid-killing activeity of the extract from the leaves of Daphne odora Thunb using different separateion methods was studied showed that the median lethal concentrateions (LC50)of the water extraction and ethanol precipitate (WEP)and ethanol precianpitate(EWP)to Macrosiphum rosivorum were 3963mg/L and 6397mg/L .
