Abstract In addition to known compounds [kushenol E, 6,8-di(3,3-dimethylally)genistein, osajin, warangalone, derrone 4′- O -methyl ether, alpinumisoflavone 4′-methyl ether and feruloyl hexadecayl ester], three new flavonoids were isolated from the roots of Euchresta horsfieldii in Thailand. By means of the spectroscopic analysis, the structures of new compounds were characterized as 5,2′,4′-trihydroxy-6-(3
摘要 除了已知化合物 [kushenol E, 6,8-di(3,3-二甲基烯丙基)genistein、osajin、warangalone、derrone 4'-O-甲基醚、alpinumisoflavone 4'-甲基醚和阿魏酰十六烷基酯],三个从泰国 Euchresta horsfieldii 的根中分离出新的黄酮类化合物。通过光谱分析,新化合物的结构特征为5,2',4'-三羟基-6-(3,3-二甲基烯丙基-6‴,6‴-二甲基吡喃[2‴,3‴:7, 8)]黄烷酮(euchrenone a 9 ),5, 4'-dihydroxy-6-(3,3-二甲基烯丙基)-5‴-hydroxyisoproyldihydrofurano [2″,3″: 7,8]异黄酮(euchrenone b 10 )和2 -甲氧基乳杆菌素。
