| 摘要: |
| 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-hydroxycinnamic acid,5)。其中,化合物2～5为首次从该植物中分离得到。 |

| Abstract: |
| The chemical components of Eucalyptus urophylla�/i>215;E. grandis were isolated and purified by various column chromatographies and their structures were identified by spectral analysis. Finally,five compounds were isolated and identified as Ellagic acid(1),3-O-methylellagic acid(2),3,3’-di-O-methylellagic acid(3),3-O-methylellagic acid 4’-O-α-L-rhamnopyranoside(4),(E)-p-hydroxycinnamic acid(5). Compounds 2-5 were isolated from E. urophylla�/i>215;E. grandis for the first time. |
