运用多种色谱手段分离纯化尾巨桉的化学成分,并通过波谱法对分离到的化合物进行结构鉴定。结果表明：从尾巨桉叶和根中分离并鉴定了5个化合物,分别为鞣花酸(ellagic acid,1)、3-O-甲基并没食子酸(3-O-methylellagic acid,2)、3,3′-O-二甲基鞣花酸(3,3′-di-O-methylellagic acid,3)、3-O-甲基鞣花酸4′-O-α-L-吡喃鼠李糖苷(3-O-methylellagic acid 4′-O-α-L-rhamnopyranoside,4)、反式对羟基肉桂酸((E )-p-hydroxy-cinnamic acid,5)。其中,化合物2~5为首次从该植物中分离得到。
運用多種色譜手段分離純化尾巨桉的化學成分,併通過波譜法對分離到的化閤物進行結構鑒定。結果錶明：從尾巨桉葉和根中分離併鑒定瞭5箇化閤物,分彆為鞣花痠(ellagic acid,1)、3-O-甲基併沒食子痠(3-O-methylellagic acid,2)、3,3′-O-二甲基鞣花痠(3,3′-di-O-methylellagic acid,3)、3-O-甲基鞣花痠4′-O-α-L-吡喃鼠李糖苷(3-O-methylellagic acid 4′-O-α-L-rhamnopyranoside,4)、反式對羥基肉桂痠((E )-p-hydroxy-cinnamic acid,5)。其中,化閤物2~5為首次從該植物中分離得到。
