从西南远志乙醇提取液中分离得到5个黄酮类化合物,通过现代波谱学方法分别鉴定为:1,7,二甲氧基-2,3-二羟基酮;1,2,3-三甲氧基-7-羟基酮;1,3,6-三羟基-2,7-二甲氧基酮;1,2,7-三甲氧基-3-羟基酮;1,2,3,7-四甲氧基酮。
Five flavonoids were isolated from the ethanol extracts of Polygala tenuifolia Willd in Southwestern China and identified by modern spectroscopic methods as follows: 1,7-dimethoxy-2,3-dihydroxychromanone; 1,2,3-trimethoxy- Hydroxy-2-methyl-7-hydroxy-2-hydroxy-2-methyl-3-hydroxy- 7-tetramethoxycholorone.
