T. Tanaka et al., DISTRIBUTION OF ELLAGIC ACID-DERIVATIVES AND A DIARYLHEPTANOID IN WOOD OF PLATYCARYA-STROBILACEA, Phytochemistry, 47(5), 1998, pp. 851-854
4-O-Xylosides of ellagic acid, 3'-O-methylellagic acid and 3,3'-di-O-m
ethylellagic acid have been isolated from the sapwood of Platycarya st
robilacea; these compounds were absent in the heartwood. A new dipheny
lether-type diarylheptanoid, named platycarynol, was also isolated fro
m the heartwood, together with ellagic acid, 3'-O-methylellagic acid a
nd two known terpenoids. (C) 1998 Elsevier Science Ltd. All rights res
