Objective. To examine rice organochlorine pesticides in several districts in Hunan so as to provide security reference for production of pharmaceutical glucose which was made with broken rice and a reasonable range for the application of organic pesticides.
Method. A modified method of Chinese Pharmacopoeia was used to extract and prepare the samples which were analyzed by gas chromatography equipped with SE-54 fused silica capillary column (3.0 m ´ 0.25 mm ´ 0.32 mm) and electronic capture detector, the nine organic chlorine pesticides were separated by column temperature program and their contents could be measured and calculated by external standard method.
Result. The results showed that the nine organic chlorine pesticides could be accurately determined by the proposed method. The content of organic chlorine conformed to Chinese Government Standards for rice.
Conclusion. The proposed method was so fast, simple and accurate that it could be used to determine organic chlorine pesticide in rice. The rice in these districts can be used for rice glucose production.
