摘要: 利用多种柱色谱和高效液相色谱相结合的方法从木麻黄(Casuarina equisetifolia)凋落物的乙酸乙酯提取物中分离得到7个单体化合物,通过波谱分析结合理化性质鉴定化合物结构分别为:3β-(p-hydroxy-trans-cinnamoyloxy)olean-12-en-28-oicacid (1),3-O-(E)-coumaroylerythrodiol (2),casuarmondtol (3),alnusdiol (4),山柰酚-3-O-α-L-鼠李糖苷 (5),4″-反-香豆酰基-山柰酚-3-O-α-L-鼠李糖苷 (6),山柰酚 (7),其中化合物3、4、6和7为首次从该植物中分离得到。分别采用MTT法、Ellman法和PNPG法对单体化合物的体外细胞毒活性、乙酰胆碱酯酶抑制活性和α-糖苷酶抑制活性进行测试,测试结果表明,化合物1和6具有细胞毒活性,化合物1~4和6具有乙酰胆碱酯酶抑制活性,化合物1和3~5具有α-糖苷酶抑制活性。

Abstract: Seven compounds were isolated from the ethyl acetate (EtOAc) extract of litters of Casuarina equisetifolia by the method of column chromatography and high performance liquid chromatography.Their structures were identified as 3β-(p-Hydroxy-trans-cinnamoyloxy)olean-12-en-28-oicacid (1),3-O-(E)-coumaroylerythrodiol (2),casuarmondtol (3),alnusdiol (4),kaempferol3-O-α-L-rhamnopyranoside (5),4′′-trans-p-coumaroyl-kaempferol-3-O-α-rhamnopyranoside (6) and kaempferol (7) on the basis of physicochemical properties and spectroscopic evidence.Compounds 3,4,6 and 7 were obtained from Casuarina equisetifolia for the first time.The compounds were tested for cytotoxicity,acetylcholinesterase and α-glucosidase inhibitory activities by MTT,Elman and PNPG methods,respectively.Compounds 1 and 6 showed cytotoxic activity.Compounds 1-4 and 6 showed acetylcholinesterase inhibitory activity.In addition,compounds 1 and 3-5 exhibited α-glucosidase inhibitory activity.

Key words: Casuarina equisetifolia, Litters, chemical constituents, cytotoxicity activity, acetylcholinesterase inhibitory activity, α-glucosidase inhibitory activity
