摘要

Abstract A new flavonoid, gossypetin-7, 8, 3′, 4′-tetramethyl ether (3, 5-dihydroxy-7, 8, 3′, 4′-tetramethoxyflavone) was isolated and its structure elucidated by chemical and spectroscopic methods. The known flavonoids 5-hydroxy-6, 7, 3′, 4′-tetramethoxyflavone and artemetin were also isolated. Chemical transformations led to the conclusion that the structure previously reported as '8, 3′, 4′-trimethoxyizalpinin'(3, 5-dihydroxy-7, 8, 3′, 4 ...
