Study on Detection of Organochlorine Pesticide Residue in Ginseng

To investigate the residue situation of pesticides in ginseng, total 17 samples of ginseng-growing soil, ginseng roots and ginseng seeds were collected from 5 regions of Fusong County, and the contents of organochlorine pesticide residues in the samples were detected by using ultrasonic-assisted extraction and gas chromatography with acetone-ligroin as the solvent, thereby providing suitable recommendations and scientific basis for the selection of ginseng-growing soil.

气相色谱法测定人参中BHC残留量

本文研究了一种快速、简便、准确地测定人参中ＢＨＣ残留量的气相色谱法。人参样品经正己烷—丙酮冷浸泡，超声萃取，磺化法处理后，萃取液直接上机测定。本方法对人参中ＢＨＣ各异构体的回收率均在８５％以上。变异系数小于１０％。与其它方法相比，本法耗时少，价格廉，结果准确，适合批量样品测定。
