Title: Chemical composition of the essential oil of Artabotrys odoratissimus Authors: Garg, S C; Siddiqui, Nafeesa Abstract: The essential oil (0.24%) from the leaves of Artabotrys odoratissimus R.Br. has been analysed by chromatographic, spectroscopic and chemical methods. Fifteen constituents (96.13%) have been characterised. The oil has been found rich in terpinen-4-ol (38.63%), caryophyllene oxide (11.78%) and linalool (11.17%). Page(s): 1229-1230
