Using gas chromatography (GC), the organochlorine insecticide residues were determined in Lonicera japonica Thunb. flowers. The results showed that the amount of organochlorine insecticide in L. japonica flowers collected from Fengqiu in He’nan Province, Pingyi in Shandong Province was less than 0.01 mg·kg ^-1. The average recoveries added in samples were 93.54%-98.85%, RSD≤6.8%. It shows that the amount of organochlorine insecticide in L. japonica flowers accords with the demands of traditional Chinese medicine production.
