title: Chemical constituents of Nepalese propolis (II).
abstract: A novel flavanonol (1), three new isoflavones (2-4) and a new flavan-3-ol (5) were isolated along with ten other known flavonoids (6-15) from the methanolic extract of propolis collected from Chitwan, Nepal. Their structures were determined on the basis of spectral analysis.
