摘要 目的研究三白草根的化学成分。方法采用超临界CO_2萃取,硅胶、MCI和制备高效液相色谱等色谱技术分离纯化,根据理化性质和波谱数据鉴定其化学结构。结果分离并鉴定出17个化合物,分别为:橙黄胡椒酰胺乙酸酯(1)、echinuline(2)、(-)-(7R,8R)-7-O-acetylpolysphorin(3)、榄香脂素(4)、异榄香脂素(5)、1,4-二(3,4-二甲氧基苯基)-2,3-二甲基-丁二酮(6)、saucerneol D(7)、(2R)-3-(3',4',5'-三甲氧基苯基)-1,2-丙二醇(8)、grandisin(9)、rel-(7R,8R,7'R,8'R)-3',4'-methylenedioxy-3,4,5,5'-tetramethoxy-7,7-epoxylignan(10)、zanthopyranone(11)、(±)-eritro-1-(3,4,5-trimetoxyphenyl)-1,2-propanodiol(12)、threo-3,4,5-trimethoxy-7-hydroxy-1'-allyl-3',5'-dimethoxy-8.O.4'-neolignan(13)、(+)-(8R)-(2,6-dimethoxy-4-propenylphenoxy)-1-(3,4,5-trimethoxyphenyl)propan-1-one(14)、内消旋二氢愈创木酯酸(15)、(-)-galbacin(16)和(-)-(7R,8R)-7-O-acetylraphidecursinol B(17)。结论化合物6为新的天然产物,化合物1~2、4~6、8~9、11~13为首次从该植物中分离得到。 OBJECTIVE To study the chemical constituents from the rhizome of Saururus chinensis. METHODS The chemical constituents from the rhizome of Saururus chinensis were extracted by supercritical C02 extraction and isolated by various chromatograph- ic methods, such as silica gel, MCI and pre-HPLC. Their structures were elucidated by physico-chemical constants and spectroscopic methods. RESULTS Seventeen compounds were isolated and identified as aurantiamide acetate (1) , echinuline (2) , ( - )-(7R, 8R) -7-O-acetylpolysphorin ( 3 ), elemicin ( 4 ), isoelemicin ( 5 ), 1,4-bis ( 3,4-dimethyoxyphenyl ) -2,3-dimethyl-1,4-butanedione ( 6 ), saucerneol D ( 7 ), (2R) -3- ( 3' ,4', 5 '-trimethoxyphenyl) -1,2-propanediol ( 8 ), grandisin ( 9 ), rel- ( 7R, 8R, 7 'R, 8 'R) -3', 4 '- methylenedioxy-3 ,4 ,5 ,5 '-tetramethoxy-7,7-epoxylignan ( 10 ), zanthopyranone ( 11 ), ( + ) -eritro-l-( 3,4,5-trimethoxy) -1,2-propan- odiol ( 12 ), threo-3,4,5-trimethoxy-7-hydroxy-1 ' -allyl-3 ', 5'-dimethoxy-8. O. 4 '-neolignan ( 13 ), ( + ) - ( 8R ) - ( 2,6-dimethoxy-4 -pro- penylphenoxy)-1-(3,4,5-trimethoxyphenyl) propan-l-one ( 14), meso-dihydroguaiaretic acid( 15 ), ( - ) -galbacin ( 16), and ( - ) - (7R,8R)-7-O-acetylraphidecursinol B (17). CONCLUSION Compound 6 is a new natural compound. Compounds 1 -2, 4 -6, 8 -9 and 11 -13 are isolated from this plant for the first time.
