Methods The total cantharidin obtained with acidolysis method and the free cantharidin obtained with direct extraction method were determined in eight species of Meloidae and the control species Huechys sanguinea (Homoptera: Cicadidae) by gas chromatography, and the content of the bound cantharidin in each species was calculated with the content difference between the total cantharidin and the free cantharidin. The relationship between the contents of the bound cantharidin and the contents of Ca and Mg elements in Meloidae were assessed.

摘 要：本文对番木瓜不同抗性的品种感染环斑花叶病毒后，可溶性蛋白含量和电泳谱带以及还原糖含量的变化规律进行了研究，并分析其与抗性的关系。

S extract had an inhibition effect against Sphaerotheca fuligenea,The inhibition rate was 100% when extract concentration was 20mg/mL and the inhibition rate got to 67.66% even at the concentration of 2.5mg/mL. The extract of E. humifusa had different preventive effects against four strains of S. fuliginea from four districts in Shanghai. The preventive effects on the Qibao and Baoshan were better than those of Nanhui and Qingpu. The microorganism inhibition experiment by filter papers indicated that the extract of E. humifusa had higher inhibition effect against bacteria than on pathogenic fungus. Diameters of the zone of inhibition of salmonellas, Echerichia coli and Staphylococcus aureus were 15.77mm, 12.27mm and 10.53mm respectively. The extract of E. humifusa had a certain effect against Colletotrichum lagenarium, Botrytis cinerea, Rhizoctomia solan and Pyricularia oryza but no effect against Helminthosporium maydis and Gibberella zea. The 4 cation exchange resins and ethanol deposition were used to isolate the active fractions from supernate after alkali deposition.
