It is supposed that some pesticides remain in Ginseng Radix and even in their manufactured goods, because so much insecticides are used for protecting the growing vegetable against the attacks of insects and microorganisms. One of the objects of this report is screening the residues in those preparations. The other is to devise the method for reduction in residue concentration. The results are as follows: 1. BHC isomers were found in all samples (0.27-2.96 ppm), while p,p'-DDT and p,p'-DDE were in 20 samples (0.03-1.09 ppm). 2. Of cyclodiene insecticides, heptachlor and heptachlor epoxide were found only in samples originated in Korea (0.04-2.25 ppm), whereas dieldrin only in those originated in Japan (0.07-6.03 ppm). 3: Of the preparations originated in Japan, white ginsengs and fibers in which little dieldrin were detected showed relatively high content of total BHC and p,p'-DDT together with its metabolite. 4. The concentration of organochlorine pesticide residues in the epidermis and lateral roots was higher than those in white ginseng. 5. Less insecticidal residue was found in red ginsengs and ginseng extracts than in others. On the basis of physicochemical properties, it is possible to decrease the residue to the levels which are acceptable for human consumption.
