The essential oil components of cedar heartwoods play an important role in the durability of these trees. Yet, the composition of these oils and identity of many of the compounds remains unknown, or incompletely know for some commercially important cedar heartwoods. The essential oil extracts of Alaska Yellow Cedar (Chamaecyparis...
The purpose of this work was to investigate possibilities
of raising lavender in Oregon of desirable qualities and.
yield. This was carried out by analysis and study of the
properties of the oil obtained therefrom in order that a
comparison with other kinds of lavender oil might be made.
The umbellulone was isolated from the myrtle oil by the
sulfite method, which was found to be the most inexpensive
and convenient method of obtaining the pure ketone.
The umbellulone was hydrogenated in the vapor phase
over a nickel catalyst, passing it through an electric tube
furnace, in an attempt...
This work set out to examine whether ethanol content can influence the human detection of volatile hop compounds in beer. Advances in chromatography have identified hundreds of chemical compounds in the essential oil of hops but only a fraction are directly associated with "hoppy" aroma. To screen compounds, sensory detection...
