摘要: Abstract Soluble enzyme preparations from Salvia officinalis convert the acyclic precursor [1- 3 H 2 ,G- 14 C]geranyl pyrophosphate to cyclic monoterpenes of pinane (α-pinene,β-pinene), isocamphane (camphene), p -menthane (limonene,1,8-cineole), and bornane (bornyl pyrophosphate, determined as borneol) type without loss tritium, significant conversion other free intermediates. Similarly, C]geraniol is converted in intact S. leaves monoterpene olefins 1,8-cineole, well isothujone camphor, tritium C(1). These results clearly eliminate transcis isomerization geranyl neryl via aldehyde intermediates prior cyclization, they support a scheme whereby trans cyclized directly by way bound linaloyl intermediate.
