This work was done to establish a systematic analytical method for organochlorine pesticide residues in commercial crude drugs. The chief problem is to find cleanup methods which make the test solution an adequate one for gas chromatographic analysis. For this purpose, three steps were devised: preliminary cleanup with acetonitrile-hexane partition, cleanup on florisil columu, and final cleanup on silica gel or MgO-celite column. Concentration of total BHC ranged 0.15 to 2. 74 ppm in all of the 22 commercial crude drugs tested. Cyclodiene insecticides were detected in roots and rhizomes. Comparatively large amount of BHC isomers, p, p'-DDT and its metabolite was found in leaves and stems, but smaller amount of those was detected in fruits and seeds. In addition, permissible levels of organochlorine pesticides were calculated from ADI and human consumption of each crude drug.
