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。 Objective To study the chemical composition of the upper part of cultivated licorice. Methods The compounds were separated by solvent method and chromatography, and their structures were identified by spectroscopic methods. As a result, seven aliphatic compounds were isolated and identified as undecanoic acid, 2-(4-hydroxyphenyl)ethylester (), glyceryl 1-dodecanate. (docosanoicacid, 2,3-dihydroxypropylester)(),tetracosanoic acid (2,3-dihydroxypropylester)(), 1-docosamate-2,3-isopropylidene glycerol Ester [docosanoicacid,(2,2-dimethyl-1,3-dioxolan-4-yl)methylester](),1-(22-hydroxydodecanic acid)glyceride (docosanoicacid,22-hydroxy-,2, 3-dihydroxypropylester) (), 1-(24-hydroxytetracosanoic acid) glyceride (tetracosanoic acid, 24-hydroxy-, 2,3-dihydroxypropylester) (), palmitic acid (). Conclusion The compound is a new compound, the compound ~ is the first separation of this genus, and the compound is the first separation of the plant.
