摘要
以乙醇、乙酸乙酯、氯仿3种溶剂作为夹带剂,对胡芦巴植物种子干粉进行超临界CO2萃取(SCFE),其中以乙醇作夹带剂的萃取得率最高,所得到的超临界CO2萃取物对玉米象、谷蠹、杂拟谷盗成虫的触杀活性均较强。
ethyl acetate and chloroform were used as modifier for supercritieal CO2 extraction （SCFE） of bioactive substance from TFG seeds powder, and the extraction rates of TFG- SCFE with alcohol （TFG-- SCFE-- A）, TFG-- SCFE with ethyl acetate （TFG-- SCFE-- E）, TFG-- SCFE with chloroform （TFG--SCFE--C）, and TFG--SCFE without modifier were 14.17%, 13.31%, 10.74% and 10.18% respectively. Among the four extracts, TFG--SCFE--A extracts was the best pesticide againstS, zeamais., R. dominica and Tribolium con fusum Herbst .
