| The evaluation of organochlorine pesticides in raw materials of traditional Chinese medicine (TCM)
is essential to the quality control of TCM. In this study, the contents of organochlorine pesticides in 14
raw materials of TCM as follows, Aconiti Lateralis Praeparata Radix, Citri Reticulatae Pericarpium Viride,
Sophorae Flavescentis Radix, Curcumae Rhizoma, Astragali Radix, Farfarae Fl肘， Polyporus, Trichosanthis
Radix, Gastrodiae Rhizoma, Alpiniae Officinari Rhizoma, Angelicae Pubescentis Radix, Cimicifugae Rhizoma,
Fritil1ariae Cirrhosae Bulbus and Red Ginseng were investigated. For each raw materia1 of TCM, the residues
of 11 organochlorine pesticides, such as aldrin, BHC, chlordane, DDT, dicofol, dieldrin, endosulfan, endrin,
heptachlor, hexachlorobenzene, and quintoze間， were ana1yzed by GCÆCD and comfirmed by GCIMS. τ'wenty
samples per raw material of TCM were tested. The result showed that all 20 samples of Red Ginseng were
found to contain PCNB of 0.047-16.610 ppm and 18 samples contained hexachlorobenzene of 0.004-1.224
ppm. Among 20 samples of Red Ginseng, 6 samples were over limit of PCNB. Besides, 17 samples of Ci肘
Reticulatae Pericarpium Viride contained dicofol of 0.083-5.789 ppm, 2 samples of Trichosanthis Radix
contained DDT of 0.007 ppm, one sample of Polyporus contained chlordane of 0.067 ppm, one sample of
Astraga1i Radix contained DDT of 0.016 ppm and one sample of Farfarae Flos contained hexachlorobenzene of
0.006 ppm. The results of this survey can serve as 由e references for the regulatory authority. |
