【摘要】：目的:研究藏药宽筋藤极性部位的化学成分。方法:采用硅胶柱层析、半制备液相色谱和Sephadex LH-20色谱,重结晶等方法进行分离纯化,运用波谱数据并结合文献鉴定化学结构。结果:从藏药宽筋藤中分离得到12个化合物,分别鉴定为:宽筋藤苷A(1)、宽筋藤苷B(2)、Cyclo(D-Tyr-D-Tyr)(3)、反式丁香苷(4)、tinoscorside D(5)、turpinionoside A(6)、3,4-dimethoxyphenyl-O-β-D-apiofuranosyl-(1→6)-β-D-glucopyranoside(7)、3,4,5-trimethoxyphenyl-O-β-D-apiofuranosyl-(1→6)-β-D-glucopyranoside(8)、lcariside F2(9)、顺式丁香苷(10)、corchoionoside C(11)、松脂素(12)。结论:其中,化合物3、6~11均为首次从该植物中分离得到。
[Abstract]:Objective: to study the chemical constituents of polar parts of Rhizoma Magnolia, methods: silica gel column chromatography, semi-preparative liquid chromatography and Sephadex LH-20 chromatography, recrystallization were used to separate and purify them. Results: twelve compounds were isolated and identified as Atenoside A1H, CycloD-Tyr-D-Tyroscorside D5tinionoscorside D5tinionoside D5tinionoside Aturonoside Aturonoside Aturonoside, 34-dimethoxyphenyl-O- 尾 -D-apiuranosyl-O- 尾 -D-apiuranosyl-1, respectively, as determined by spectroscopic data and literature. The chemical structures were identified as follows: Auranosyl-O- 尾 -D-apiuranosyl-1, CycloD-Tyr-D-Tyroscorside D5tinionoside Aturonoside Aturonoside Aturonoside. 鈫，
