Abstract

Chemical investigation of the n-butanol extract from the methanol extract of the root bark of Artocarpus nobilis furnished four new prenylated flavonoids together with artonin E 2'-methylether (4), isoartonin E 2'-methylether (5), dihydroisoartonin E 2'-methylether (6), artonin V 2'-methylether (7), artobiloxanthone (1), artonin E (2) and cycloartobiloxanthone (3). All these compounds showed strong radical scavenging properties towards DPPH radical.

摘要

对面包树（Artocarpus nobilis）根皮甲醇提取物的正丁醇提取物进行化学研究，得到了四种新的异戊烯基黄酮类化合物，以及雅顿宁E 2'-甲醚（4）、异雅顿宁E 2'-甲醚（5）、二氢异雅顿宁E 2'-甲醚（6）、雅顿宁V 2'-甲醚（7）、面包树黄烷酮（1）、雅顿宁E（2）和环面包树黄烷酮（3）。所有这些化合物对DPPH自由基均表现出较强的自由基清除性能。
