New compounds with small rings in essential oils

Despite the continuing discovery of new synthetic fragrance raw materials, essential oils still remain the other half of the foundation of perfumery. Consequently, the analysis of essential oils is still very much of interest, as is illustrated by the excellent series of articles by Lawrence in this journal. We now wish to report a number of products containing small (three-, four-, and five-membered) rings, most of which are found for the first time in essential oils. These products were isolated by chemical group separation, liquid and gas chromatography, whereupon the structures were determined by mass, infrared and NMR spectroscopy. All structures were confirmed by synthesis. The essential oils used were obtained from regular commercial sources.

Process to Formulate Hypoallergenic Jasmin Oil

We must also turn our attention to problems of safety in fragrance materials other than allergenicity; we must consider dermal irritation and phototoxicity as well. Finally, I have to say that formulation of safe fragrance materials cannot be accomplished by cosmetic companies alone. The cooperation of perfumers, perfume companies and such organizations as RIFM (Research Institute for Fragrance Materials) and IFRA (International Fragrance Association) is sure to accomplish this goal.

Turkish Rose Oil Research: Recent Results

ose oil was produced by hydrodistillation from fresh flowers of Rosa damascena Miller. (Turkey and Bulgaria are the two main producers of this precious material.) Results of the analysis of Turkish rose oil produced by the Gülbirlik Cooperative in the past 16 years are provided in this article.

Comparative Investigations of the Essential Oil and Volatiles of Spearmint

The objective of this work is to identify the fragrance compounds of this oil and its SPME-headspace by means of gas chromatographic- spectroscopic (GC and GC/MS using different polar and chiral phases) and olfactoric methods (GC-sniffing technique and olfactory correlations) to find out the importance of each single constituent with their specific odor attributes, responsible for the characteristic and pleasant spearmint aroma for the first time.

Investigating New Essential Oils: Rationale, Results and Limitations

Research in new essential oils may provide benefits (missing aroma notes, new sources of isolates, new chiral compounds), but it must reassert its originality and vigor and it must recognize the constraints of economics and regulations.

Parameter test distillations for the superficial essential oils

Every effort was made to ensure that the herb used in the three 1975 distillations was a similar as possible. The same applied to the 1976 season's tests. Nonetheless, the smaller charges consistently return smaller yields of oil per kilo. This is due to an orderly phenomenon that could be discussed on another occasion.

Aromatherapy: Do Essential Oils Have Therapeutic Properties?

A pleasant odor has always been, and still is, an important factor for people to feel good, and feeling well is synonymous with good health. Therefore, we can conclude that all substances which are able to create a certain amount of well-being and well-feeling possess therapeutic properties and, therefore, can be called therapeutic agents.

A New Method of Separation of Citral from Lemongrass Oil

Although many methods are known for the separation of citral from lemongrass (Cymbopogen flexuosus) oil, like fractional distillation, adduct formation and regeneration, the purity and the yield of citral as separated are not satisfactory. A new method for separation of citral in pure form and in near quantitative yield uses the column chromatographic technique. This method may also be adapted for large scale separation of citral and hence can be of commercial importance.
