Abstract

From Viburnum awabuki K. KOCH (Caprifoliaceae), four new acetyl glucosides of scopoletin, 2'6'-di-o-acetylscopolin (1), 3', 6'-di-O-acetylscopolin (2), 6'-O-acetylscopolin (3) and 2'-O-acetylscopolin (4), and two lupane-type triterpenes, 6α-hydroxylup-20(29)-en-3-on-28-oic acid (6) and its 6β-epimer (7), were isolated. Their structures were elucidated on the basis of physicochemical evidence, including proton and carbon-13 nuclear magnetic resonance spectrometry.
