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 25
o
C.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 C
