OCCURRENCE OF PROCYANIDINS IN NELIA MEYERI

A novel natural 4-arylflavan-3-ol has been obtained from leaves of Nelia meyeri.The same extract contains two procyanidin dimers, B-2 and B-5, and trimer C-1. 1H NMR studies furnish diagnostic chemical shift parameters for determining the points of linkag

THE FIRST NATURALLY OCCURRING 4-ARYL FLAVAN-3-OL

(2R,3R,4S)-4-(2,4,6-trihydroxyphenyl)flavan-3,3',4',5,7-pentaol, the first natural 4-aryl flavan-3-ol, was isolated from Nelia meyeri Schwant., and its structure and stereochemistry determined by spectroscopic investigation and synthesis.
