title: Volvalerenol A, a new triterpenoid with a 12-membered ring from Valeriana hardwickii.
abstract: Volvalerenol A (1), an unprecedented type of triterpenoid with a 7/12/7 tricyclic ring system, was obtained from the ethanol extracts of the roots of Valeriana hardwickii. The structure and relative configurations were established by comprehensive analysis of MS and NMR spectroscopic data. The possible biogenetic pathway of 1 was also deduced.
