摘　　要：用乙醇水加热回流法提取侧柏叶总黄酮,并就提取物对槐蚜的杀虫活性进行了测定。结果表明:室内叶片法生测后,提取物对槐蚜毒效的LC50为13.71mg/mL;田间防治效果测定,当浓度为30mg/mL时,对槐蚜的防治效果为85.19%。因此,侧柏叶总黄酮对槐蚜有较好的杀虫效果。The total flavonoids of Platycladus orientalis leaves was extracted with alcohol-water solution by heating to reflux for 2 hours,and the insecticidal activities of extracts were detected against Aphis sophoricola Zhang. The results showed that the total flavonoids of indoor leaf bioassay were toxic to Aphis sophoricola Zhang with LC;0 of t3. 71 nag/mL： The results of the control efficiency determination experiment in the field indicated that the control efficiency of the total flavonoids was 85, 19% against the insect when the concentration of extracts was 30 mg/mL. Therefore, the total flavonoids of Platycladus orientalis leaves had a good insecticidal activity against Aphis sophoricola Zhang.
