(17) Four neutral metabolites, 6-exo-hydroxycamphene, 10-hydroxycamphene, and diastereoisomers of camphene-2,10-glycol, were identified and two alcohols, 7-hydroxycamphene and 3-hydroxytricyclene, were estimated by IR, UV, NMR, and mass spectra and chemical degradations.
(18) (+)-Pinene cyclase from sage (Salvia officinalis) catalyzes the isomerization and cyclization of geranyl pyrophosphate to (+)-alpha-pinene and (+)-camphene, and to lesser amounts of (+)-limonene, myrcene, and terpinolene, whereas (-)-pinene cyclase from this tissue catalyzes the conversion of the acyclic precursor to (-)-alpha-pinene, (-)-beta-pinene, and (-)-camphene, and to lesser quantities of (-)-limonene, myrcene, and terpinolene.
(19) Cyclase I from Salvia officinalis leaf catalyzes the conversion of geranyl pyrophosphate to the stereo-chemically related bicyclic monoterpenes (+)-alpha-pinene and (+)-camphene and to lesser quantities of monocyclic and acyclic olefins, whereas cyclase II from this plant tissue converts the same acyclic precursor to (-)-alpha-pinene, (-)-beta-pinene and (-)-camphene as well as to lesser amounts of monocyclics and acyclics.
