ENANTIOMERIC COMPOSITION OF MONOTERPENE HYDROCARBONS FROM THE LIVERWORT CONOCEPHALUM CONICUM
Volatiles from the essential oil of the liverwort Conocephalum conicum were analysed.The chirality of the monoterpene hydrocarbons was studied by two-dimensional gas chromatography.All compounds except β-phellandrene showed high optical purity.For the identification of enantiomers, (+)-β-phellandrene and (-)-α-thujene were prepared from (+)-limonene and (+)-sabinene, respectively.Key Word Index: Conocephalum conicum; Hepaticae; liverwort; monoterpene hydrocarbons; (+)-β-phellandrene; (-)-α-thujene; chiral composition
