Alkaloid constituents from Uncaria rhynchophylla and their anti-inflammatory activity

  • 摘要: 通过HPLC和柱色谱法对钩藤带钩茎的茎叶中化学成分进行分离提纯,使用核磁共振波谱技术对化合物结构进行鉴定,分别为dihyrdocorynantheine( 1 ),isocorynantheidine( 2 ),毛钩藤碱( 3 ),柯楠因碱( 4 ),去氢毛钩藤碱( 5 ),蓬籽嗪甲醚( 6 ),villocarine A( 7 ),16R-E-isositsirikine( 8 ),sitsirikine( 9 ),19,20-dihydroisositsirikine( 10 ),去氢毛钩藤N-氧化物( 11 ),geissoschizine N-oxide methyl ether( 12 ),柯诺辛碱( 13 ),异钩藤酸( 14 ),异柯诺辛因碱( 15 ),柯诺辛碱B( 16 ),去氢钩藤碱( 17 ),阿枯阿米精( 18 ). 化合物 2,7,810 为首次在该植物中分离得到. 通过炎症小体的实验,化合物 13 表现出一定的抗炎活性.

     

    Abstract: The chemical constituents from Uncaria rhynchophylla were isolated and purefied by column chromatography on silica gel, aluminum oxide, Sephadex LH-20 and HPLC. The structure of the compounds were elucidated by spectral analysis. Eighteen compounds were isolated and identified, including dihyrdocorynantheine ( 1 ), isocorynantheidine ( 2 ), hirsutine ( 3 ), corynantheine ( 4 ), hirsuteine ( 5 ), geissoschizine methyl ether ( 6 ), villocarine A ( 7 ), 16R-E-isositsirikine ( 8 ), sitsirikine ( 9 ), 19, 20-dihydroisositsirikine ( 10 ), hirsuteine N-oxide ( 11 ), geissoschizine N-oxide methyl ether ( 12 ), corynoxine ( 13 ), isorhynchophyllic acid ( 14 ), isocorynoxeine ( 15 ), corynoxine B ( 16 ), corynoxeine ( 17 ), akuammigine ( 18 ). Compound 2, 7, 8 and 10 were first isolated from Uncaria rhynchophylla. And compound 13 showed modest anti-inflammatory activity.
