摘要: 通过浸提法,结合单因素、响应面法优化蛇床子[Cnidium monnieri (L.) Cuss.]中总黄酮的提取工艺条件,并进行杀虫抑菌活性测试。结果表明,蛇床子总黄酮的最优提取条件是蛇床子粉末10 g,乙醇体积分数为64%,提取时间为23 min,溶剂体积为85 mL,黄酮实测得率为7.83%;杀虫活性测定试验中 1.0 mg/mL蛇床子提取物对苹果黄蚜(Hyalopterus amygdali)和朱砂叶螨(Tetranychina harti)的48 h校正死亡率均大于50%,且2种试虫的校正死亡率存在显著差异,LC50分别为0.041、0.086 mg/mL;抑菌活性表明蛇床子提取物对番茄灰霉病菌的抑制活性最好,EC50为21.29 mg/L,对苹果腐烂病菌和油菜菌核病菌也具有较强的抑菌活性。

Abstract: The extraction conditions of total flavonoids from Cnidium monnieri (L.) Cuss.were optimized by extraction method combined with single factor and response surface method, and the insecticidal and antibacterial activities were tested. The results showed that the optimum extraction conditions were as follows: The Cnidium monnieri powder 10 g, the concentration of ethanol was 64%, the extraction time was 23 min, the solvent volume was 85 mL, and the measured yield of flavonoids was 7.83%. In the insecticidal activity test, the 48 h corrected mortality of 1.0 mg/mL Cnidium monnieri extract against Hyalopterus amygdali and Tetranychina harti was greater than 50%, and the corrected mortality of the two test insects was significantly different, with LC50 of 0.041 and 0.086 mg/mL, respectively. The antibacterial activity showed that the extract of Cnidium monnieri had the best inhibitory activity against Botrytis cinerea, and the EC50 was 21.29 mg/L. It also had strong antibacterial activity against Valsa mali and Sclerotinia sclerotiorum.

Key words: Cnidium monnieri (L.) Cuss., total flavonoids, response surface method, insecticidal activity, antifungal activity
