According to the current research status of pesticide residues in Chinese herbal medicines

the best pesticide detection and removal method should be screened in order to reduce or avoid pesticide residue in Chinese herbal medicines. On the basis of recent literatures on Chinese pesticide residue

we summarized the type

detection method and the removal of pesticide residue in Chinese herbal medicines

and screened out the best methods for pesticide detection and removal. At present

the organochlorine pesticides were the main residue matters. The main detection methods of pesticide residue were gas-mass spectrometry (GC-MS) or gas chromatography (GC) testing

and pesticide residue removal relied mainly on supercritical fluid extraction method.
