The isolate 85-1 was propagated on Datura stramonium and purified by PEG precipitation, two cycles of differential centri-fugation and sucrose density gradient centrifugation. The virus yield was 0.1 mg/ kg of fresh plant material.

分离物85-1在曼陀罗上繁殖，经PEG沉淀，两次差速离心和蔗糖梯度离心后的得毒率为0.1mg/kg材料。

【 Results 】 The optimal process conditions for Flos Datura were as follows: soaking the medicinal material for 2 hours with 10 times of 75% alcohol, with continuous radiation for 25 min at the power of 730 W, at 65 ℃.

【结果】洋金花微波提取的最佳工艺条件是用药材10倍量的体积分数为75%乙醇浸泡2.0h，在功率为730W，温度为65℃的微波条件下连续辐射25min。

IIPC ( Interference index of population control) was applied to evaluate the effects of drive action of extracts from Datura stramonium and Metaplexis japonica to Tetranychus truncatus, which were extracted by methanol and alcohol.

应用干扰作用控制指数（IIPC）评价了曼陀罗与萝艹摩的甲醇和乙醇提取物对截形叶螨实验种群的干扰作用。
