<br/>Development and improvement of analytical method for residual pesticides in oriental herbal medicines for ensuring the safety management of pesticides and providing the safety food supply chain for consumers. Scientific and technical improvements on current MFDS official methods for analysis of pesticide residues in oriental herbal medicines were undertaken. The analytical procedures including extraction, partition, purification and determination were verified and standardized to be eligible for the official purpose. For validation of analytical method, ILOQ(instrumental limit of quantitation), MLOQ(method limit of quantitation), linearity of calibration curve, repeatability, specificity were calculated and conducted on oriental herbal medicines. The established method was satisfied criteria of the analytical method for pesticide residues, which covered 70~120% recovery range, less than 20% of relative standard derivations, and higher sensitivity than 0.05 mg/kg of limit of quantitation or half of maximum residue limits. The method established in this study could be applied to most of oriental herbal medicine as an official and general method for the residual pesticide analysis.<br/>
