Abstract

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.

Abstract

Ardisiacrenoside I (1), a new triterpenoid pentasaccharide with an unusual glycosyl glycerol side chain, was isolated from Ardisia crenata together with five closely related triterpenoid saponins. Their structures were elucidated by a combination of mass spectrometry, IR, 1D, and 2D NMR spectroscopy. Their cytotoxic activities were evaluated against several different human tumor cell lines by the 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyl tetrazolium bromide (MTT) method.
