【摘要】：目的:對蒺藜科(Tribulus L.)四合木屬(Tetraena Maxim.)強旱生落葉小灌木蒙古四合木(Tetraena mongolica Maxim.)的地上部分進行化學成分研究,并鑒定其所含的化學成分。方法:取四合木地上部位(1Kg)用95%乙醇回流提取,濃縮除去醇后制成水的混懸液,分別用石油醚、氯仿、乙酸乙酯和和正丁醇進行萃取,減壓回收溶劑得到不同極性的萃取部位。各部位利用硅膠柱色譜法、Sephadex LH 20凝膠色譜法,薄層色譜法,制備高效液相色譜法等方法進行分離,純化得到化合物。并根據(jù)化合物的理化性質分析、波譜解析、對照品比較及與文獻報道對比鑒定其結構。結果:四合木地上部位中共分離得到11個化合物,鑒定出11個化合物。從氯仿層鑒定出4個化合物;乙酸乙酯層鑒定出7個化合物。分別是:(1)3,4-二羥基苯甲醛(3,4-Dihydroxybenzaldehyde)(2)兒茶素(Catechin)(3)表沒食子兒茶素(釹-釺-epigallocatechin)(4)沒食子兒茶素(釹-釺-gallocatechin)(5)8-dihydroxy-1,3,5-trimethoxyxanthone(6)olean-11-oxo-12-en-28-ol-3β-yl-caffeate(7)槲皮素(Quercetin)(8)槲皮素-3-O-β-D-葡萄糖苷(Quercetin3-O-β-D-APG)(9)古柯二醇(Erythrodiol olean-2-en-3,28-diol)(10)異鼠李素-3-O-β-D-葡萄糖苷(Isorhamnrtin-3-O-β-D-APG)(11)3-Cyclohexen-1-one,4-[3β-D-glucopyranosyloxy)butyl]-3,5,5-trimethyl。結論:本課題利用光譜等數(shù)據(jù)對于四合木的化學成分進行研究,共分離鑒定出11個化合物,其中化合物11為未見文獻報道的新化合物。
[Abstract]:Objective: to study the effect of Tribulus L.on Tribulus L. Tetraena Maxim. Tetraena mongolica Maxim., a deciduous shrub, Tetraena mongolica. The above-ground part was studied and its chemical constituents were identified. Methods: the above ground part of tetrahedron was extracted by 95% ethanol refluxing and concentrated to make water suspension. The suspension was extracted with petroleum ether, chloroform, ethyl acetate and n-butanol, respectively, and the solvent was recovered at low pressure to obtain different polarity parts. The compounds were isolated and purified by silica gel column chromatography Sephadex LH 20 gel chromatography, thin layer chromatography and high performance liquid chromatography. The structures of the compounds were identified according to their physical and chemical properties, spectral analysis, comparison of reference substances and comparison with literature reports. Results: 11 compounds were isolated and 11 compounds were identified. Four compounds were identified from chloroform layer and 7 compounds from ethyl acetate layer. 鍒嗗埆鏄，
