Abstract
The essential oil of the seed of C. cyminum Linn cultivated in Pakistan was studied for the first time with respect to its physicochemical constants and chemical composition. Samples of the oil as distilled from the seed of the Peshawar and Quetta regions were obtained in 3.5 and 3.0% yields and consisted of .alpha.-pinene (1.1 and 0.7%), .beta.-pinene (14.3 and 19.7%), limonene (0.4 and 1.5%), .gamma.-terpinene (11.5 and 16.3%) p-cymene (6.0 and 2.7%), cuminaldehyde (22.4 and 20.0%), 1,4-p-menthadien-7-al (23.6 and 24.3%), 1,3-p-menthadian-7-al (13.5 and 11.5%) and cuminyl alcohol (7.2 and 3.7%), respectively. The Pakistan cumin seed contains a volatile oil comparable to those recorded for seed of good commercial quality from other geographical sources.
