摘要
目的:研究绿茎槲寄生的活性化学成分。方法:对绿茎槲寄生的乙醇提取物的有效部位,即醋酸乙酯溶解部分中主要化学成分进行分离鉴定,并经体外活性筛选,寻找促PC12细胞分化的活性物质。结果:获得了5个主要化学成分,即北美圣草素(1),5,7-二羟基-3′,4′-二甲氧基-二氢黄酮(2),齐墩果酸(3),5,7-二羟基色原酮(4),高北美圣草素(5)。经活性筛选试验发现,化合物高北美圣草素(5)具有促PC12细胞分化作用。结论:成分1-5均为首次从该植物中分离得到,并找到了活性单体成分高北美圣草素。
Objective. To investigate chemical constituents of the stem of Viscum nudum and their bioacyivity. Method: The major chemical constituents were isolated from the AcOEt-solved part of ethanol-extract of the plant by column chromatography and the active screenhag test in vitro were taken out for looking for compounds to acccelerate PC12 cell differentiation. Result: 5 compounds were identified as eriodictyol (1), 5, 7-dihydroxy-3′, 4′-dimethoxy flavanone (2), oleanolie (3), 5, 7-dihydroxychromone (4) and homefiodietyol (5) by spectral evidences, in which homeriodictyol (5) had acceleration differentiation to PC12 cell. Conclusion: All compounds were obtained from this plant for the first time, and bioaetive constituent was observed in the AeOEt-solved part.
