Hydroxylation of 1,8-cineole by Mucor ramannianus and Aspergillus niger [PDF]

Brazilian Journal of Microbiology, 2015
The monoterpenoid 1,8-cineole is obtained from the leaves of Eucalyptus globulus and it has important biological activities. It is a cheap natural substrate because it is a by-product of the Eucalyptus cultivation for wood and pulp production. In this study, it was evaluated the potential of three filamentous fungi in the biotransformation of 1,8 ...

Preparation and Absolute Configuration of (1,4)-(+)-3-Oxo-, (1,4)-(-)-3-Oxo- and (1,3,4)-(+)-3-Acetyloxy-5-oxo-1,8-cineole

Natural Product Communications, 2009
Enantiomerically pure (1S,4S)-(-)-3-oxo-1,8-cineole (-)-2 and (1R,4R)-(+)-3-oxo-1,8-cineole (+)-2 were prepared for the first time and their absolute configurations assigned by vibrational circular dichroism (VCD) measurements. Thus, treatment of cineole

Gastroprotective Mechanisms of the Monoterpene 1,8-Cineole (Eucalyptol)

PLOS ONE, 2015
Recently, our research group identified and reported 1,8-cineole (CIN), a monoterpene that naturally occur in many aromatic plants, as one of the major constituent of the essential oil from leaves of Hyptis martiusii (EOHM), as well as characterized the gastroprotective action of this oil.

The Reaction of 1,8-Cineole with Acid Solutions [PDF]

Bulletin of the Chemical Society of Japan, 1958
Abstract The reaction of 1,8-cineole with 60% acetic acid at 70°C for 10 hours under stirring gave dl-α-terpineol (0.12%) and trans terpin (0.03%). By the action of 21% sulfuric acid at 70°C for 3 hours, cineole yielded dl-α-terpineol (4.6%), terpin hydrate (0.20%), trans-terpin (0.12%) and monocyclic hydrocarbons (a small amount).

A detailed view on 1,8-cineol biosynthesis by Streptomyces clavuligerus [PDF]

Beilstein Journal of Organic Chemistry, 2016
The stereochemical course of the cyclisation reaction catalysed by the bacterial 1,8-cineol synthase from Streptomyces clavuligerus was investigated using stereospecifically deuterated substrates. In contrast to the well investigated plant enzyme from Salvia officinalis, the reaction proceeds via (S)-linalyl diphosphate and the (S)-terpinyl cation ...

Enhanced chlorhexidine skin penetration with eucalyptus oil [PDF]

, 2010
Background Chlorhexidine digluconate (CHG) is a widely used skin antiseptic, however it poorly penetrates the skin, limiting its efficacy against microorganisms residing beneath the surface layers of skin. The aim of the current study was to improve the
