摘要
本研究对白虫茧蜂的寻主利它素粗提物进行了薄层层析、纸层层析的初步分离,结果纸层层析的分离效果较好,得到一个活性斑点,Rf 为0.85,进一步对活性斑进行 HPLC 的分离及馏分收集,得到若干馏分,通过实验室生物测定,证明其中有活性的馏分只有一个。
The extract of the host-searching kairomone of Bracon grecni was isolated by
the thin-layer chromatography and paper chromatography.The result of isolation
of the paper chromatography was better than that of the thin-layer chromatography.
The active spot(Rf is 0.85)was isolated and collected by HPLC.The lab bioassay
result shawed was only one that there active fraction peak in it.
