Contribution to the study of the chemical composition of the essential oil from the terminal branches of the cypress tree in the Grasse area

In a previous study of the chemical composition of the essential oil derived from the Algerian cypress, we compared the oil with oil obtained by steam distillation of the terminal branches of cypress trees from the Grasse area. We then noted some differences that affected the relative proportions of certain constituents. The richness in high constituents, in particular, prompted us to begin the study of this higher fraction. Cypress essential oil possesses a dry-down odor which is both woody and amberlike and is greatly appreciated by perfumers; this also makes it worth studying.
