Abstract Eleven flavonoids, including two new compounds, were isolated from Gutierrezia texana : the structures of the new compounds are 5,7,2′,5′-tetrahydroxy-3,4′-dimethoxyflavone and 5′-acetoxy-5,7,2′-trihydroxy-3,4′-dimethoxyflavone. The nine known compounds are 5,4′,5′-trihydroxy-3,6,7,8-tetramethoxyflavone, 5,7,2′,5′-tetrahydroxy-3,6,4′-trimethoxyflavone, 5,7,3′-trihydroxy-3,4′-dimethoxyflavone
摘要 从 Gutierrezia texana 中分离得到 11 种黄酮类化合物,包括两种新化合物:新化合物的结构为 5,7,2',5'-四羟基-3,4'-二甲氧基黄酮和 5'-乙酰氧基-5,7, 2'-三羟基-3,4'-二甲氧基黄酮。九种已知化合物是 5,4',5'-三羟基-3,6,7,8-四甲氧基黄酮,5,7,2',5'-四羟基-3,6,4'-三甲氧基黄酮,5,7, 3'-三羟基-3,4'-二甲氧基黄酮, 5,7,3',4'-四羟基黄酮, 3,5,7,3',4'-五羟基黄酮, 5,7,3',4'-四羟基- 3-甲氧基黄酮、5,6,7,3',4',-五羟基-3-甲氧基黄酮, 5,7,3',4'-四羟基-3-甲氧基黄酮 7-O-葡萄糖苷和 3,5,7, 3',4'-五羟基黄烷酮。
