目的对茜草科拉拉藤属植物蓬子菜(Galium verumL.)全草的体积分数为95%的乙醇溶液提取物进行分离并鉴定。方法采用硅胶柱色谱等方法分离化学成分,1H-NMR、13C-NMR等方法进行结构鉴定。结果从体积分数为95%的乙醇溶液提取物中分离得到6个化合物,分别鉴定为2,5-二羟基-1-甲氧基-蒽醌(2,5-dihydroxy-1-methoxyanthraquinone,1)、1-羟基-2-羟甲基-3-甲氧基-蒽醌(1-hydroxy-2-hydroxymethy-3-methoxyanthraquinine,2)、环烯醚萜内酯(morindolide,3)、水晶兰苷(monotropein,4)、去乙酰车叶草苷酸(deacetylasperulosidic acid,5)、6α-羟基-京尼平苷(6α-hydrox-ygeniposide,6)。结论化合物1、2、3为从本属植物中首次分离得到。
OBJECTIVE To isolate and identify 95% ethanol extract from the whole plant of Galium verum L.grass. Methods The constituents were separated by silica gel column chromatography and identified by 1H-NMR and 13C-NMR. Results Six compounds were isolated from 95% ethanol solution and identified as 2,5-dihydroxy-1-methoxyanthraquinone (1) , 1-hydroxy-2-hydroxymethy-3-methoxyanthraquinine (2), morindolide (3) monotropein (4), deacetylasperulosidic acid (5) and 6α-hydroxye-genipinide (6). Conclusion Compounds 1, 2 and 3 were isolated from this genus for the first time.
