Title StatementThe leaf volatile oil of Nothopanax fruticosum (L.) Miq
Physical Description141-160, illus
Summary, Etc.The study was conducted to identify the components of the volatile oil of the leaves of N. frticosum, particularly sesquiterpenes for which the oil gave a remarkably positive test. Hydrosteam distillation of the fresh leaves of N. fruticosum gave a 0.32% yield of volatile oil. The oil was light yellow in color with a grassy note scent. Its refractive index was 1.5001 at 25oC.Tests revealed that the oil is negative for the presence of sulfur and nitrogen but highly positive for the presence of sesquiterpene. Gas liquid chromatography coupled with mass spectroscopy analysis of the oil showed the presence of ∞-bergamotene, oxygenated sesquiterpene C15H16O2 1-ethyl-1-methyl-1-2-(1-methyl1-ethenyl)-4-(1-methylethylidene)-cyclohexane, ∝-elemene, β-bourbonene, β-cubebene, β-bisabolene, ∝-farnesene, ∝-elemene, β-elemene, ∝-cadinene, ∝-elemene, ∝-copaene. Further toxicity tests were recommended in order to determine its feasibility as a legitimate spray pesticide for house insect pests
