Sweet flag rhizome (Acorus calamus L.) oil was extracted by supercritical fluid extraction method. Different temperature levels (45, 55 and 65 °C) and pressure levels (100, 150 and 200 bar) were selected for the optimization of the parameters for SC-CO2 extraction process. The highest extraction yield of 3.15 g/100 g at the rate of 90.08% were obtained at 45 °C and pressure of 200 bar. The quality of sweet flag rhizome oil was analysed and determined by using HPLC and the β-asarone content in oil were recorded at the rate of 26.80%. Further, the oil has been tested for its insecticidal activity against pulse beetles with different levels of concentration (10 to 70 μl/ml). The insecticidal activity of oil was found to be increased with increase in oil concentration and exposure time. The highest mortality of pulse beetles were observed in treatment T7 (70 μl/ml) on 7th day of storage.
