摘要

(+)-cis-Sabinene hydrate and (+)-trans-sabinene hydrate are the main monoterpenes found in O. majorana, but can also be found in other Origanum species. The synthesis of sabinene hydrate in O. majorana is performed by sabinene hydrate synthase. It is claimed that both (+)-cis- and (+)-trans-sabinene hydrate are produced by the same enzyme in a ratio of 10:1. To verify this in vitro result in vivo, we analysed single plants of 20 different genotypes of O. majorana and 3 different populations of O. microphyllum (collected from Crete, Greece), all grown in Germany, and calculated the ratios of (+)-cis- to (+)-trans-sabinene hydrates. In O. majorana a constant ratio of 20:1 was found, whereas in O. microphyllum the ratio did not prove to be constant.
