摘要

以七烷基(6- o -t-丁基硅基-2,3-二- o -乙基)-β-环糊精为手性固定相，测定了樟脑在精油中的对映体比例。香菜油(Coriandrum sativum L.)的对映体(1S)-(-)含量在72-75%之间过量。相反，鼠尾草(鼠尾草)和罗勒(basilicum L.)精油中(1R)-(+)的对映体过量(>)为90%，鼠尾草为50% - 70%)和罗勒(basimum basilicum L.)为94%。

Update on enantiomeric composition of (1R)-(+)- and (1S)-(–)-camphor in essential oils by enantioselective gas chromatography

The enantiomeric ratios of camphor have been determined in authentic essential oils, using heptakis(6-O-t-butylsilyl-2,3-di-O-ethyl)-β-cyclodextrin as the chiral stationary phase. An enantiomeric excess of (1S)-(–) within 72–75% is characteristic of coriander oil (Coriandrum sativum L.). Contrary, an enantiomeric excess of (1R)-(+) characterizes the essential oils of sage (>90% for Salvia sclarea L. and 50–70% for Salvia officinalis L.) and of basil (>94% for Ocimum basilicum L.).
