摘  要:目的:研究金银花Lonicerajaponica中的抗补体活性酚酸类成分。方法:通过溶血试验方法进行抗补体活性成分的导向分离,对所得化合物进行抗补体活性测定,采用现代波谱技术ESI-MS,^1H-NMR,^13C-NMR进行结构鉴定。结果:从金银花乙酸乙酯部位分离得到了14个化合物,其中有8个酚酸类、3个环烯醚萜类和3个黄酮类成分,包括新绿原酸(1)、绿原酸(2)、隐绿原酸(3)、3,5-O-二咖啡酰奎宁酸(4)、4,5-O-二咖啡酰奎宁酸(5)、3,4-D-二咖啡酰奎宁酸(6)、咖啡酸(7)、咖啡酸甲酯(8)、裂环马钱苷(9)、獐芽菜苷(10)、断氧化马钱子苷(11)、木犀草素(12)、槲皮素(13)、山柰酚(14)。抗补体实验表明化合物1~9,11~14对经典的补体激活具有不同程度的抑制作用,以3,5-O-二咖啡酰奎宁酸活性最强。结论:化合物14首次从金银花中分离得到,酚酸类化合物是金银花中的主要抗补体活性成分,3,5-O-二咖啡酰奎宁酸活性最强,值得深入研究。Objective: To study the anti-complementary phenolic acids from Lonicera japonica. Method: The anti-complementary activity-directed isolation was carried out with the hemolysis test as guide. All isolation was evaluated for their in vitro anti-complemen- tary activities. The structures were identified by various spectroscopic data including ESI-MS, ^1 H-NMR, ^13 C-NMR data. Result: Four- teen compounds were isolated from the EtOAc fraction of L. japonica extracts, including 8 phenolic acids: 5-O-caffeoylquinic acid(l), chlorogenic (2), 4-O-caffeoylquinic acid ( 3 ), 3,5-di-O-caffeoylquinic acid ( 4 ), 4,5-di-O-caffeoylquinic acid ( 5 ), 3,4-di-O-caf- feoylquinic acid ( 6 ), caffeic acid ( 7 ) and methyl caffeate acid ( 8 ) ; 3 iridoids : secologanoside ( 9 ), sweroside (10) and secoxyloganin ( 11 ) ; and 3 flavonoids : luteolin ( 12), quercetin (13) and kaempferol (14) . Compounds 1-9 and 11-14 showed anti-complementary activity in different extents and 3,5-di-O-caffeoylquinic acid(4) exhibited the most significant activity against the classical pathway. Conclusion: Compound 14 is obtained from this plant for the first time, phenolic acids are the main anti-complementary constituents of L. japonica and 3,5-di-O-caffeoylquinic acid(4) is a potential complement inhibitor with strong activity, which worthy to be studied further in the future.
