title: Chemical constituents from the ethanol extract of Viburnum ternatum.
abstract: Phytochemical investigation of the 70% ethanol extract from Viburnum ternatum resulted in the isolation of three new compounds, vibsanol-9'-al (1), 4-methoxy-vibsanol (2), and 5,7-dihydroxy-4'-methoxyflavanone(8 → 3')-5,7-dihydroxy-4'-methoxyflavone (4), together with a known compound vibsanol (3). Their structures were determined on the basis of spectroscopic analyses, including 1D and 2D NMR (COSY, HMQC, HMBC, and NOESY) and HR-ESI-MS analyses.
