The essential oils from the dried stems of Ephedra sinica, E. intermedia and E. equisetina were analyzed by GC-MS qualitatively and GC quantitatively. One hundred and twenty-seven constituents were identified, l-alpha-terpineol (31.64%) in E. sinica, 1,4-cineole (12.80%) in E. intermedia

Behavioral phenotyping of mice is often compromised by manual interventions of the experimenter and limited throughput. Here, we describe a fully automated behavior setup that allows for quantitative analysis of mouse olfaction with minimized experimenter involvement. Mice are group-housed and

A cytochrome P-450-dependent monooxygenase system that catalyzes the stereospecific hydroxylation of the monoterpene substrate 1,4-cineole was demonstrated in cell-free preparations of Bacillus cereus UI-1477. 1,4-Cineole hydroxylations were catalyzed by a 100,000 x g (1-h)-centrifuging soluble, hexane-inducible enzyme that activated and
