Gas Chromatographic Analysis on Turkish Rose Oil, Absolute and Concrete

The analysis of rose products maybe realized by gas or liquid chromatographic techniques. Our investigations showed that liquid chromatography have been used only in a few studies to separate essential oils and terpenoid compounds, and a sufficient separation has not been obtained.

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.

More Perfume Materiak from Isoprene

We should all realize that the new Toxic Substances Control Act, which Congress is about to pass, will increase considerably the cost of developing new aroma chemicals. The new law may reduce the number of such chemicals drastically. Closer cooperation between the fragrance and the aroma chemical industries will now be even more important in order to maintain a healthy level of innovation in areas of mutual interest.

Il. Scientific Prospects from 1.5 Million Responses

Our collaboration with the National Geographic Society on the Smell Survey is particularly gratifying. As scientists, it is part of our responsibility to inform the public. And as researchers, it is our hope to tap ever greater sources of information about human physiology and behavior. I believe these two goals are beautifully intertwined in this project.

Separation of Fragrance Materials from Perfumed Consumer Products

In isolating the fragrance materials, which are usually present only at low levels, the analytical chemist is confronted with a formidable separation challenge, particularly when the sample also contains emulsifiers, surfactants, clarifiers, thickeners, solubilizers, pigments, antioxidant, UV-absorbers, preservatives, solvents, and other materials.

Spectroscopic characterisation of a rare monoterpene from Blumea Mollis

Beginning with earlier studies on the essential oil separated from different species of Blumea, this material has been the subject of many chemical and biological investigations. Chemical investigations of the oils of different Blumea species have afforded different terpenoids. Thus the oil of Blumea eriantha has a major constituent, d-carvotanacetone; oil of Blumea lacera contains the cineol, d-fenchone and citral; oil of Blumea malcolmii yielded d-carvotanacetone and 1-tetrahydrocarvone; and the oil of Blumea membranceae contains 1,4-(8)-p-methadiene; δ-cadinene; 2,3-dimethoxy-p-cymene; 1,2-dimethyl-3-isopropenyl cyclopent-1-en-4-one; 5-hydroxy-p-cymene-2-oxybornylene; 2-methyl-5-isopropyl cyclopent-1-one carbonylic acid methyl ester; and citronellyl acetate. But this monoterpene has not been reported yet.
