ENANTIOMERIC COMPOSITION OF MONOTERPENE HYDROCARBONS FROM THE LIVERWORT CONOCEPHALUM CONICUM

Article abstract of DOI:10.1016/0031-9422(92)83457-A

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
