目的研究甘草Glycyrrhiza uralensis废渣的化学成分。方法采用硅胶吸附柱色谱、Sephadex LH-20柱色谱、高效液相色谱等分离手段进行分离纯化,根据化合物的理化性质和波谱数据鉴定化合物的结构。结果从新疆产甘草废渣75%乙醇提取物中分离得到了5个化合物,分别鉴定为槐香豆素C(1)、3β-O-对羟基-反-肉桂酰-齐墩果酸(2)、3-羰基甘草次酸(3)、3β,18-O-异丙叉-8(14),15-异右松脂烷二烯(4)、3β,18-O-异丙叉-7,15-异右松脂烷二烯(5)。结论化合物1为新的香豆素类化合物,命名为槐香豆素C;化合物2、4、5为首次从该属植物中分离得到。
Objective To study the chemical constituents of licorice Glycyrrhiza uralensis residue. Methods The compounds were separated and purified by silica gel column chromatography, Sephadex LH-20 column chromatography and high performance liquid chromatography (HPLC). The structures of the compounds were identified according to the physicochemical properties and spectral data of the compounds. Results Five compounds were isolated from the 75% ethanol extract of licorice residue in Xinjiang and identified as 2 (2), 2, 3, 3-carbonylglycyrrhetinic acid (3), 3β, 18-O-isopropylidene-8 (14) 15-iso-right pinarin (5). Conclusions Compound 1 is a new coumarin named as Sophocarbene C. Compounds 2, 4 and 5 are isolated from this genus for the first time.
