Flavonol glycosides and monoterpenoids from Potentilla anserina.
Potentilin A (1), a rare diflavonol ester of mu-truxinic acid and a new normonoterpenoid, 2,6-dimethyl-2,3-dihydro-4-oxo-4H-pyran-2-acetic acid (2), was isolated from Potentilla anserina, together with 19 known flavonol glycosides (3-21) and 2 known monterpenoids (22,23). Their structures were elucidated by means of UV, IR, HR-ESI-MS, 1D and 2D NMR spectroscopic data.
