Pinguisane-Type Sesquiterpenes from the South American Liverwort Porella recurva (Taylor) Kuhnemann
The chemical composition of a dichloromethane extract of the South American liverwort Porella recurva has been examined. Two new pinguisane-type norsesquiterpenoid natural products were isolated: 6,11-epoxy-15-nor-3,4-dioxo-5,10-pinguisadien-12-acetate and 6,11-epoxy-15-nor-4-oxo-5,10-pinguisadien-12-acetate. In addition two known pinguisane-type sesquiterpenes were also isolated: norpinguisone and norpinguisone methyl ester. All structures were elucidated by means of NMR spectroscopic techniques and mass spectrometry.

(E,E)-α-Farnesene the Main Substance of the Volatiles of the Flowers from European Mistletoe (Viscum album L.)
(E,E)-α-Farnesene was extracted as the main component of the volatile fraction of male Viscum album L. Male and female flowers of V. album L. growing on different host trees were analysed by solid phase microextraction and by lipophilic extraction.
