Based on the Thin Layer Chromatography methods, it indicated that α and β asarone were predominatly present in the extracts. These results were confirmed by using High Performance Liquid Chromatography (HPLC) method. The insecticidal activities were examined using residual contact method on the coffee berry. In a test with adults of H.hampei, after a week application, the hexane fraction caused more mortality of insect than the methanol fraction.
