摘要
目的:对天山雪莲抗缺氧活性成分进行研究。方法:利用硅胶柱色谱并结合现代波谱技术对天山雪莲的化学成分进行分离纯化与结构鉴定。利用常压密闭缺氧小鼠模型,对分离得到的化合物进行抗缺氧活性评价。结果:从天山雪莲石油醚部位中分离得到12个化合物,分别鉴定为:二十八烷(1)、1-十一烷醇(2)、1-十七烷醇(3)、1-二十七烷醇(4)、肉豆蔻醚(5)、欧芹脑(6)、β-谷甾醇(7)、羽扇豆醇(8)、苏荠苎黄酮(9)、荠苎黄酮(10)、7-甲氧基黄芩素(11)、5,6-二羟基-7,8-二甲氧基黄酮(12)。结论:除化合物7、8外,其余均为首次从该植物中分离得到。抗缺氧活性实验表明:化合物1、5、8~12具有较好的抗缺氧活性。
Objective: To investigate the chemical constituents with anti-hypoxia activity from Saussurea involucrata. Methods: The chemical constituents,isolated and purified by column chromatography from Saussurea involucrata,were identified by several spectroscopic methods. The anti-hypoxic activities of these compounds were examined using the normobaric hypoxic model of mice. Results:Twelve compounds were isolated from petroleum ether extract of Saussurea involucrata and identified as n-octacosane(1),1-undecanol(2),heptadecan-1-ol(3),heptacosan-1-ol(4),myristicin(5),apiol(6),β-sitosterol(7),lupeol(8),moslosooflavone(9),mosloflavone(10),negletein(11),and 5,6-dihydroxy-7,8-dimethoxyflavone(12). Conclusion: All compounds except 7 and 8 are isolated from this plant for the first time. Compound 1,5 and 8 ~ 12 can significantly prolong the survival time of hypoxic mice.
