title: A novel aryltetralone lignan from Litsea pedunculata.
abstract: A novel aryltetralone lignan, pedunculine A (1), together with a known lignan cagayanone A (2), was isolated from the leaves and twigs of Litsea pedunculata. The structure of the new lignan was elucidated on the basis of spectroscopic methods and single-crystal X-ray diffraction.
