吐鲁番锦鸡儿地上部分化学成分的研究

Chemical constituents from the aerial parts of Caragana turfanensis

目的研究吐鲁番锦鸡儿Caragana turfanensis(Krassn.)Kom.地上部分的化学成分。方法吐鲁番锦鸡儿地上部分95%乙醇提取物采用硅胶、HPLC和重结晶等进行分离纯化,根据理化性质及波谱数据鉴定所得化合物的结构。结果从中分离得到17个化合物,分别鉴定为白黎芦醇(1)、白杉皮醇(2)、maakoline(3)、kompasinol A(4)、丁香树脂酚葡萄糖苷(5)、双环氧木脂素(6)、南烛木树脂酚(7)、山柰酚(8)、芦丁(9)、异山奈素-7-O-β-D-葡萄吡喃糖苷(10)、桂皮酸(11)、对羟基桂皮酸(12)、对羟基苯甲酸(13)、丁香酸吡喃葡萄糖苷(14)、原儿茶醛(15)、反式-咖啡酰酪胺(16)、胡萝卜苷(17)。结论化合物3、10为首次从该属植物中分离得到,化合物4、6~9、13、16为首次从该植物中分离得到。

AIM To study the chemical constituents from the aerial parts of Caragana turfanensis(Krassn.)Kom..METHODS The 95%ethanol extract from C.turfanensis was isolated and purified by silica,HPLC and recrystallization,then the structures of obtained compounds were identified by physicochemical properties and spectral data.RESULTS Seventeen compounds were isolated and identified as resveratrol(1),piceatannol(2),maakoline(3),kompasinol A(4),syringaresinol-O-β-D-glucopyranoside(5),liriodendin(6),lyoniresinol(7),kaempferol(8),rutin(9),isokaempferide-7-O-β-D-glucopyranoside(10),cinnamic acid(11),p-hydroxy cinnamic acid(12),4-hydroxybenzoic acid(13),syringate-4-O-β-glucopyranoside(14),protocatechualdehyde(15),N-trans-caffeoyl tyramine(16),and daucosterol(17).CONCLUSION Compounds 3,10 are isolated from genus Caragana for the first time,and compounds 4,6-9,13,16 are isolated from this plant for the first time.
