摘要
目的 从金缕半枫荷 Semiliquidambar cathayensis根茎抗炎有效的乙酸乙酯萃取部位分离鉴定化合物。方法 通过巴豆油鼠耳刺激药理实验确定金缕半枫荷抗炎有效部位 ,利用硅胶柱层析等手段分离单体化合物 ,借助质谱和核磁 (包括 HMQC,HMBC)等光谱学测定确定化合物结构。结果 从该植物中分离鉴定了 9个化合物 :齐墩果酸、3-羰基齐墩果酸、2 α,3β-二羟基齐墩果酸、2 α,3β,2 3-三羟基齐墩果酸、鞣酸 - 3,3′-二甲醚、鞣酸 - 3,3′,4 -三甲醚、鞣酸 - 3,3′-二甲醚 - 4 - O-β- D -木糖苷、β-谷甾醇和硬脂酸。
Object To isolate and identiified the chemical constituents from the EtOAc soluble fraction of the rhizome of Semiliquidambar cathayensis Chang with anti inflammatory activity Methods The EtOAc soluble fraction of anti inflammatory activity was determined on the basis of the mouse ear irritant assay by croton oil The chemical constituents were isolated by silica gel column chromatography, and their structures were identiified by IR, MS and NMR spectroscopic methods including HMQC and HMBC experiments Results Four oleanolic acid derivatives, oleanolic acid, 3 oxo olean 12 en 28 oic acid 2α, 3β dihydroxyolean 12 en 28 oic acid, 2α, 3β, 23 trihydroxyolean 12 en 28 oic acid (arjunolic acid); three ellagic acid derivatives, ellagic acid 3, 3′ dimethylether, ellagic acid 3, 3′, 4 trimethylether, and ellagic acid 4 O β D xylopyranoside 3, 3′ dimethylether, together with β sitosterol and octadecylic acid were obtained and identified Conclusion All the nine compounds were isolated for the first time from the title plant
