摘要
目的对蔷薇科植物月季花的化学成分进行分离和鉴定。方法本实验采用硅胶柱色谱、聚酰胺柱色谱,SephadexLH-20柱色谱和重结晶等分离纯化手段对化合物进行纯化,并根据波谱分析技术和理化性质对照等方法对化合物进行结构鉴定。结果从其石油醚和三氯甲烷部位分离得到了15个化合物,分别为:β-谷甾醇(1)、菜油甾醇(2)、环桉烯醇(3)、齐墩果酸(4)、熊果酸(5)、2α,3α,19α,23-四羟基-12-烯-28-乌苏酸(6)、2α,3α,19α,-三羟基乌苏-12-烯-28-酸(7)、山柰酚(8)、槲皮素(9)、山柰酚-3-O-β-D-葡萄糖苷(10)、山柰酚-3-O-β-D-槐糖苷(11)、槲皮素-3-O-β-D-槐糖苷(12)、槲皮素7-O-β-龙胆二糖苷(13)、银椴苷(14)、芹菜素-7-O-(6″-O-对羟基苯甲酰基)-β-D-葡萄糖苷(15)。结论其中化合物2,4,5,6,7,12,13,14,15等9个化合物,为首次从月季植物中分离得到。
OBJECTIVE To investigate the chemical constituents in Rosa chinensis Jacq. METHODS The chemical constituents were isolated and purified by silica gel, Sephadex LH-20, and recrystallization, et al. Their structures were elucidated by spectral analysis and physicochemical properties. RESULTS From petroleum ether fraction and chloroform fraction of water extraction of Rosa chinensis Jacq. , the structures of 15 compounds were identified as β-sitosterol ( 1 ), campesterol ( 2 ), cycloeucalenol ( 3 ) , oleanolic acid (4) , ursolic acid ( 5 ) , myrianthic acid ( 6 ) , euscaphic acid ( 7 ) , kaempferol ( 8 ) , quercetin ( 9 ) , campherol-3-O-β-D-glucoside ( 10), campherol-3-O-β-D-sophoroside ( 11 ) , quercetin-3-O-β-D-sophoroside ( 12 ), quercetin-7-O-β-D- gentiobioside ( 13 ) , cam- pherol-3-O-β-D- (6"-O-trans-p-coumaroyl) -glucoside ( 14 ), and apigenin-7-O- ( 6"- O-p-hydroxy benzyl) -β-D-glucoside ( 15 ). CONCLUSION Compounds 2,4,5,6,7,12,13,14 and 15 are obtained from the plant for the first time.
