Chemical constituents from the ethanol extract of Viburnum ternatum
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.
