Abstract
The chemical composition of the essential oil of the fresh and mature seeds of H. candicans collected from Murree and Kalam has been determined. The oil from the seeds of the respective localities obtained in 0.65% and 0.82% yields, is composed of .alpha.-pinene (0.27, 0.15%), p-cymene (0.82, 0%), limonene (2.66, 0.15%), curcumene (0.23, 0%), .beta.-bisabolene (0.23, 0%), cadinene (0.57, 0.64%), .beta.-selinene (0, 0.21%), .beta.-elemene (0, 0.17%), butyl butyrate (0, 0.15%), isobutyl-2-methyl butyrate (1.41, 4.45%), n-butyl isovalerate (1.26, 10.98%), n-hexyl-isobutyrate (2.21, 2.12%), butyl hexanoate (3.00, 1.13%), octyl acetate (4.50, 6.00%), hexyl-pentanoate (16.90, 3.83%) amyl acetate (10.94, 19.57%), bornyl acetate (27.12, 21.45%), hexyl caproate (9.65, 8.67%), neryl acetate (0, 0.32%), linalool (1.04, 0%), santenol (0.57, 0%), capric acid (14.08, 0%), lauric acid (0.14, 14.0%), myristic acid (0, 14.27%), palmitic acid (0, 4.21%) and santalic acid (0, 0.14%). Because of its fragrance, the essential oil of this species holds good promise of being commercialized.
