Chemical composition, toxicity and larvicidal activity of the essential oil from the whole plant of Acalypha segetalis from south-west Nigeria

摘要

The chemical composition of the essential oil from the whole plant of Acalypha segetalis Muell. Arg. was analyzed by GC and GC/MS. Nineteen volatile constituents were identified. The main compounds were α-pinene (8.5%), neophytadiene, isomer II (14.7%) and neophytadiene, isomer III (33.6%). Toxicity and larvicidal assays revealed that the plant had LC_(50) values of 14.0 μg/mL and 45.4 μg/mL respectively.
