Abstract
Several flavonoid dimers were isolated and elucidated from the bark of Korean pine tree (Pinus densiflora). One of them was postulated to be a compound, epicatechin (4¡æ7) 5,8,3¢¥,4¢¥-tetrahydroxy-(2R,3R)-flavan-3-ol, whose structural determination was carried out by diverse NMR techniques.
