title: Paeoveitols A-E from Paeonia veitchii.
abstract: Paeoveitols A-E (1-5), involving three monoterpenes and two benzofuran constituents, were isolated from Paeonia veitchii. Their structures were determined based on extensive spectral analyses (IR, UV, MS, 1D and 2D NMR), and the absolute configuration of compound 1 was confirmed by single-crystal X-ray diffraction. By the agitating human melatonin receptor 1 (MT1) assay on HEK293 cell line in vitro, compound 4 showed weak activity with the agitation rate of 22.52% at the concentration of 1.79 mM.
