栽培甘草地上部分化学成分研究

目的对栽培甘草地上部分的化学成分进行研究。方法溶剂法和色谱法分离化合物,光谱法鉴定其结构。结果分离得到7个脂肪族类化合物,分别鉴定为十一烷酸-2-对羟基苯基乙酯[undecanoicacid,2-(4-hydroxyphenyl)ethylester](),1-二十二烷酸甘油酯(docosanoicacid,2,3-dihydroxypropylester)(),1-二十四烷酸甘油酯(tetracosanoicacid,2,3-dihydroxypropylester)(),1-二十二烷酸-2,3-异亚丙基甘油酯[docosanoicacid,(2,2-dimethyl-1,3-dioxolan-4-yl)methylester](),1-(22-羟基二十二烷酸)甘油酯(docosanoicacid,22-hydroxy-,2,3-dihydroxypropylester)(),1-(24-羟基二十四烷酸)甘油酯(tetracosanoicacid,24-hydroxy-,2,3-dihydroxypropylester)(),棕榈酸(palmiticacid)()。结论化合物为新化合物,化合物～为该属植物首次分离,化合物为该种植物首次分离。

Study on the chemical constituents of aerial parts of cultivated licorice

Objective To study chemical constituents of aerial parts of cultivated licorice. Methods The compounds were isolated by chromatographic method and the structures were identified on the basis of spectral analysis. Result Seven compounds were elucidated as undecanoic acid, 2-(4-hydroxyphenyl)ethyl ester)(Ⅰ), docosanoic acid, 2,3-dihydroxypropyl ester)(Ⅱ), tetracosanoic acid, 2,3-dihydroxypropyl ester(Ⅲ), docosanoic acid, (2,2-dimethyl-1,3-dioxolan-4-yl)methyl ester)(Ⅳ), docosanoic acid, 22-hydroxy-,2,3-dihydroxypropyl ester(Ⅴ), tetracosanoic acid, 24-hydroxy-,2,3-dihydroxypropyl ester)(Ⅵ), and palmitic acid(Ⅶ). Conclusion CompoundⅠis a new compound. CompoundⅡ-Ⅵ were isolated for the first time from genus glycyrrhiza and compound Ⅶ was isolated for the first time from this plant.
