Planifolin, a new naphthopyranone dimer and flavonoids from Paepalanthus planifolius

J Nat Prod. 2001 Jan;64(1):122-4. doi: 10.1021/np000325t.

Abstract

A new naphthopyranone dimer (1) named planifolin was isolated from a methylene chloride extract of the capitula of Paepalanthus planifolius. The structure of 1 has been determined by chemical and spectroscopic means. In addition, a known dihydronaphthopyranone glycoside and seven known flavonoids were isolated from an ethanolic extract of the leaves of P. planifolius.
