Supercritical fluid extraction of oil from sweet flag rhizome (Acorus calamus L.) and its insecticidal activity on pulse beetles (Callosobruchus maculatus)

In view of this applications the present study is designed for the extraction of oil from the rhizome by supercritical fluid extraction method, β-asarone content in the extracted oil and its impact on the pulse beetles (Callosobruchus maculatus).
