A new benzofuranolignan and a new flavonol derivative from the stem of Morus australis

A new benzofuranolignan austrafuran A (1) and a new flavonol derivative 5,7,2',4'-tetrahydroxy-3-methoxyflavone (2) were isolated from the stem of Morus australis. Their structures were determined on the basis of spectroscopic evidences. (c) 2007 De Quart Yu. Published by Elsevier B.V. on behalf of Chinese Chemical Society. All rights reserved.
