The behavior of some pesticide residues in stored medicinal plants samples

Abstract Levels of 14 organochlorine pesticide residues—1,1,1-trichloro-2,2-bis(p-chlorophenyl)ethane (DDT) group (p,p'-DDT, p,p'-DDT, p,&-DDD, and p,&-DDE), HCH isomers (α-, ß-, and γ-HCH), hexachlorobenzene (HCB), aldrin, dieldrin, endrin, heptachlor, α-endosulfan, and endosulfan sulfate—were evaluated in 127 samples of medicinal plants collected in pharmacies (78 samples) and herb stores (49 samples) in 1996. Samples were divided between 15 national brands and 7 foreign brands. Most samples sold in pharmacies contained residues of γ-HCH (51.3%). All residues were detected in analyzed samples, with exception of endrin in herb store samples. Detection frequency varied between 51.3% for γ-HCH and 1.3% for endrin in pharmacy samples, and between 34.7% for HCB and 4.1 % for endosulfan sulfate in herb store samples. Maximum residue levels were exceeded in 38 (48.7%) pharmacy samples and in 26 (53.1 %) medicinal herb store samples.

due to the disordering and robbing exploration, the development of natural medicinal plant resources is facing severe habitat and social environment pressure that may touch the law in the process of getting raw materials from plants. Based on the above problems, to develop and enhance the distribution census about the new medicinal plant resources is a good way to cope with the resource shortages. In addition, for the validated medicinal plants, the scaled and standardized production is also an effective mean. Moreover, we should also have the whole dynamic management about the standardized production. That is to say, we should choose the excellent genetic resources, consider the regional characteristics, complete the gardens environment evaluation, grasp the best harvest time and strengthen the detection of the pesticide residues and heavy metal.
