摘要
目的:研究五加科人参属常用中药红参的化学成分。方法:采用硅胶柱色谱、反相柱色谱、Sephadex LH-20柱色谱、半制备液相色谱等方法分离纯化,根据理化性质和波谱鉴定化合物的结构。结果:从红参中分离并鉴定了14个化合物,结构分别为:三七皂苷R2(1),20(S)-人参皂苷Rg3(2),20(R)-人参皂苷Rg3(3),20(S)-人参皂苷Rg2(4),20(R)-人参皂苷Rg2(5),20(S)-人参皂苷Rh1(6),20(R)-人参皂苷Rh1(7),人参皂苷Rh4(8),-Ro(9),-Rb1(10),-Rg1(11),-Re(12),-Rf(13),麦芽酚(14)。结论:化合物1,4,6为首次从红参中分到的人参皂苷类成分。化合物2与3,4与5,6与7分别为3对对映异构体,其中对映异构体6与7为首次分离得到的单体。
The chemical constituents of Chinese red ginseng (Panax ginseng) were investigated. The chemical constituents were isolated and purified by silca gel, ODS, and Sephedex LH-20, column chromatography, and preparative HPLC. Their chemical structures were elucidated on the basis of physicochemical properties and spectra data. Fourteen compounds were isolated and identified as: notoginsenoside R2 ( 1 ), 20 (S) -ginsenoside Rg3 (2), 20 (R) -ginsenoside Rg3 (3), 20 ( S ) -ginsenoside Rg2 (4), 20 ( R ) -ginsenosideRg2 (5), 20 (S) -ginsenoside RhI ( 6 ), 20 (R) -ginsenoside Rh1 ( 7 ), ginsenoside Rh4 ( 8 ), -Ro ( 9 ), -Rbt ( 10 ), -Rg1 ( 11 ), Re- ( 12 ), Rf( 13 ), maltol ( 14 ). Compounds 1,4,6, were obtained from red ginseng for the first time. Compounds 2 and 3, 4 and $-7 were enantiomers respectively, enantiomers 6 and 7 were isolated as monomer for the first time.
