Aryltetralin lignans from Podophyllum hexandrum and Podophyllum peltatum
David E. Jackson,Paul M. Dewick +1 more
TL;DR: Roots of Podophyllum hexandrum and P. peltatum contain the same range of ten aryltetralin lignans, although the relative proportions are markedly different, and 4′-demethylisopicropodophyllone may well be an artefact resulting from epimerization of 4′ -demethylpodophyllotoxone.

Biosynthetic relationship of aryltetralin lactone lignans to dibenzylbutyrolactone lignans
Widad M. Kamil,Paul M. Dewick +1 more
TL;DR: Feeding experiments in Podophyllum hexandrum plants have shown that the dibenzylbutyrolactone lignan yatein is a satisfactory precursor of the aryltetralin lignAn podophyllotoxin, and a biosynthetic sequence from yate in to podophyLLotoxin via a key quinonemethide intermediate is proposed.
