【摘要】 荨麻科荨麻属植物狭叶荨麻(Urtica angustifolia Fisch ex Hornem)是民间常用药荨麻的主要来源之一,具有祛风通络、平肝定惊、消积通便、解毒等功效。民间广泛用于治疗风湿关节痛、产后抽风、小儿惊风、荨麻疹、慢性气管炎、糖尿病、毒蛇咬伤等。狭叶荨麻是多年生草本植物,生命力极强,广泛分布于黑吉辽、晋冀鲁和内蒙古地区,天然资源十分丰富,有较高的药用价值和经济价值等待开发。近年来荨麻的抗炎、抗风湿作用引起了各国学者的注意,国外对于欧产荨麻属植物的研究已较成熟。目前国内尚未见对狭叶荨麻的深入研究,迄今为止对该植物成分研究仅限于其微量元素的含量分析,尤其是对其显著的抗风湿作用的作用机理和物质基础研究尚属空白。故本文以其为研究对象,进行其化学成分的研究,研究成果将对狭叶荨麻今后的药理、药效及临床等深入研究具有重要的参考价值。本实验对狭叶荨麻的95%乙醇提取物进行了化学成分研究,从中分离得到10个化合物,利用理化方法和1H-NMR、13C-NMR、MS等波谱方法鉴定其中5个化合物,分别是5,7,4′-三羟基-3′-甲氧基-黄酮醇(异鼠李素isorhamnetin)、槲皮素-3-O-β-D-葡萄吡喃糖苷(quercetin-3-O-β-D-glucopyranoside)、反-对羟基桂皮酸(trans-4-Hydroxycinnamic acid)、山柰酚-3-O-β-D-葡萄糖苷(Kaempferol-3-O-β-D-glucoside)、胡萝卜苷(daucosterol),这五个化合物均为首次从狭叶荨麻中分离得到。另外几个化合物的结构鉴定工作正在进行。本文的研究结果为狭叶荨麻的深入研究奠定了基础,时开发利用黑龙江丰富的荨麻药用资源提供重要的科学依据。
【Abstract】 Urtica angustifolia Fisch ex Hornem,which belongs to Urticaceae,Urtica,is the main source of Nettle.It has the effect of dispelling wind and removing obstruction in the meridians,calming the liver and arresting convulsion,removing food retention and relaxing the bowels and deintoxication etc.Overseas researchers have done a lot of research on the nettle which produced in Europe,and internal research on nettle have been seen to increase day by day.U.angustifolia Fisch ex Hornem was extensively spread.It has strong bionergy,and high value of medicine and economy. So far,the research on U.angustifolia Fisch ex Hornem was restricted at the content analyses of minor element.So we focused on its chemical constituents.The solution method and chromatography have been used in this experiment, ten compounds have been isolated form this plant’s 95%EtOH extraction.By using physical and chemical methods and spectrum technology(1H-NMR、13C-NMR、MS et al.),we have identified the chemical structure of five compounds.They are isorhamnetin,quercetin- 3-O-β-D-glucopyranoside,trans-4-Hydroxycinnamic acid, Kaempferol-3-O-β-D-glucoside and daucosterol,and they are first isolated from Urtica angustifolia Fisch ex Hornem.The other compounds’s chemical structures are being identified.This experiment will ground the next chemical and pharmacological research on its result.And it will provide the researching foundation for developing research of Urtica angustifolia Fisch ex Hornem.
