摘　　要：　为筛选更有效的杀虫剂,合成了4种β-谷甾醇衍生物,用元素分析、红外光谱和质谱数据证实了其结构.杀虫活性试验表明,β-谷甾醇衍生物(2a)具有显著杀虫活性,其在乙醇溶液的最低浓度为ρ(2a)=5.0×10-5g/mL.Four kinds of β-Sitosterol derivatives are synthesized for selecting more effective insecticides, and their structures are testified by ultimate analysis, IR and MS. The experiments of insecticidal activity show that the β-Sitosterol derivatives (2a) have the best effect in killing insects and its lowest concentration in alcohol is ρ(2a)= 5.0×10^(-5) g/mL.
