摘要
茖葱(Allium Victorialis L.)为百合科葱属植物,其性微温,味辛,无毒,归肺经;具有辛散温通,芳香辟秽,用于风寒感冒,呕恶胀满之症。因茖葱有药理作用,而且无毒可食,近年来茖葱作为绿色食品,市场前景非常看好。
     本文对茖葱鳞茎的化学成分进行提取分离和结构鉴定研究。实验过程中对茖葱鳞茎的70%乙醇的提取物,进行乙酸乙酯萃取,萃取物经聚酰胺柱层析,水洗,30%乙醇洗脱,50%乙醇洗脱,95%乙醇洗脱。选择水洗物,30%乙醇洗脱物和50%乙醇洗脱物干燥后分别进行硅胶柱层析得到四个化合物。根据它们的理化性质和各种光谱(~1H-NMR,~(13)C-NMR,EI-MS等)数据的解析,确定四种化合物分别是胡萝卜苷(1),原儿茶酸(2),山奈酚(3),1—0—十六烷酸甘油酯(4)。四种化合物均为首次从茖葱鳞茎中获得。
     本文的研究结果有重要的理论价值,同时也为进一步开发利用茖葱提供一定的化学物质基础。
Alpine leek is the dried bulb of Allium victorialis L., belongs to the family of Liiiaceae.The herb is some warm and pungent in flavour, no toxin and enters lung meridian. It is used to cure common cold to due to wind-cold pathogen. Because of its pharmacological action and characteristic of no toxin, Alpine leek has already been a kind of vegetable, an organic food, so it has well development in future.
    The article researched chemical constituents extraction, isolation and identification. The bulb of A. victorialis eluted by 70% EtOH(X3).The ethyl acetate fraction from the EtOH extract of the bulb of the herb was chromatographed successively on polyamid and silica gel to afford four compounds. Using the spectra of 1H-NMR, 13C-NMR and EI-MS, we have identified chemical structures of four compounds: Daucosterol(l); Protocatechuicacid (2); Kamperol(3); l-O-hexadecanolenin(4).The four compounds were isolated from A. victorialis for the first time.
    The result of this article not only has important value in theory, but providing chemical constituents foundation for future study.
