(E,E)-alpha-farnesene the main substance of the volatiles of the flowers from European mistletoe (Viscum album L.).

(E,E)-alpha-Farnesene was extracted as the main component of the volatile fraction of male Viscum album L. Male and female flowers of V. album L.

Incorporation of [1-(13)C]1-deoxy-D-xylulose into isoprenoids of the liverwort Conocephalum conicum.

The incorporation of (13)C labeled 1-deoxy-D-xylulose into the monoterpene bornyl acetate, the sesquiterpene cubebanol, and the diterpene phytol has been studied in axenic cultures of the liverwort Conocephalum conicum. Quantitative (13)C NMR spectroscopic analysis of the labeling patterns of the sesquiterpene indicated a possible degradation of 1-deoxy-D-xylulose to acetate and subsequent incorporation via the mevalonic acid pathway. In bornyl acetate, the labeling occurred only in the acetate moiety whereas the isoprene units remained unlabelled.
