The Chemical Composition of the Leaf Essential Oils from 110 Citrus Species, Cultivars, Hybrids and Varieties of Chinese Origin

We carried out systematic analytical studies on the composition of the leaf oils from 110 citrus species, varieties, hybrids and cultivars of Chinese origin in order to look for new resources for essential oils and provide the systematic chemical-composition data of the leaf oils for the taxonomy of citrus plants.

Multidimensional Analysis of Gas Chromatographic Data, Application to the Differentiation of Clove Bud and Clove Stem Essential Oils from Madagascar

The differentiation of clove bud from clove stem oils produced in Madagascar seems to be possible using the content of less than 15 components, for each year of production. The influence of climatic conditions plays an important role on the chemical composition of these oils and more data are needed to realize a differentiation independent of the year of production or to detect an adulteration of clove bud oil with clove stem oil.

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.

Differences in Chemical and Sensory Properties of Orange Flower and Rose Oils Obtained from Hydrodistillation and from Supercritical C02 Extraction

In this article we will identify some characteristic and essential constituents of bitter orange flowers (Citrus aurantium L., ssp. armzra Engl.) from Spain, Tunisia and Morocco, and roses (Rosa damascena Mill.) from Bulgaria and Turkey, and we will discuss how the consitutents differ depending on whether the oils were isolated by hydrodistillation or by supercritical fluid carbon dioxide extraction of the concretes. hydrodistillatio norbysupercriticai fluid carbon dioxide extraction of the concretes.
