摘要
从外来入侵植物假臭草的70%乙醇提取物的乙酸乙酯萃取物中分离得到5个黄酮化合物,利用波谱方法鉴定为5,6,7,4′-四甲氧基黄酮(1),7-羟基-5,6,4′-三甲氧基黄酮(2),4′-羟基-5,6,7-三甲氧基黄酮(3),5,4′-二羟基-6,7-二甲氧基黄酮(4),5,7,4′-三羟基-6-甲氧基黄酮(5)。化合物1-5均首次从该植物中分离得到。
Five flavonoids were isolated from Eupatorium catarium,a alien invasive plant.On the basis of spectral methods,their structures were identified as 5,6,7,4′-tetramethoxyflavone(1),7-hydroxy-5,6,4′-trimethoxyflavone(2),4′-hydroxy-5,6,7-trimethoxyflavone(3),5,4′-dihydroxy-6,7-dimethoxyflavone(4) and 5,7,4′-trihydroxy-6-methoxyflavone(5).All compounds were isolated from the plant for the first time.
