摘要
运用硅胶柱色谱、ODS柱色谱、MCI柱色谱和制备型高效液相色谱等方法从仙鹤草Agrimonia pilosa 60%乙醇提取物中分离得到13个木脂素类化合物。通过理化性质和多种波谱学手段,对它们的结构进行了鉴定,分别鉴定为(7S,8S)-苏式-4,7,9,9′-四羟基-3,3′,5′-三甲氧基-8-O-4′-新木脂素(1)、(+)-4,9,9′-三羟基-3-甲氧基-3′,7-环氧-8,4′-氧新木脂素(2)、二羟基去氢二松柏醇(3)、4,9,9′-三羟基-3,3′,5-三甲氧基-4′,7-环氧-8,5′-新木脂素(4)、(-)-开环异落叶松树脂酚(5)、4,7,9,9′-四羟基-3,3′,5′-三甲氧基-8-O-4′-新木脂素(6)、(+)-异落叶松脂醇(7)、4,7,9,9′-四羟基-3,3′-二甲氧基-8-O-4′-新木脂素(8)、burselignan(9)、(-)-楝叶吴萸素B(10)、icariol A2(11)、刺五加酮(12)、(+)-4″,4■-dihydroxy-3,3′,3″,3■,5,5′-hexamethoxy-7,9′;7′,9-diepoxy-4,8″;4′,8■-bisoxy-8,8′-dineolignan-7″,7■,9″,9■-tetraol(13)。其中化合物1为新化合物,化合物1~13均为首次从龙牙草属植物中分离得到。通过实验研究,可以丰富仙鹤草中的化学成分,为后续仙鹤草生物活性研究及药效物质的阐明提供物质条件。
Thirteen lignans were isolated from 60% ethanol extract of Agrimonia pilosa by column chromatography over silica gel, ODS, and MCI and preparative high performance liquid chromatography(HPLC). Their chemical structures were identified by physiochemical properties and spectral data as(7S,8S)-threo-4,7,9,9′-tetrahydroxy-3,3′,5′-trimethoxy-8-O-4′-neolignan(1),(+)-4,9,9′-trihydroxy-3-methoxy-3′,7-epoxy-8,4′-oxyneolignan(2), dihydrodehydro-diconiferyl alcohol(3), 4,9,9′-trihydroxy-3,3′,5-trimethoxy-4′,7-epoxy-8,5′-neolignan(4),(-)-secoisolariciresinol(5), 4,7,9,9′-tetrahydroxy-3,3′,5′-trimethoxy-8-O-4′-neolignan(6),(+)-isolariciresinol(7), 4,7,9,9′-tetrahydroxy-3,3′-dimethoxy-8-O-4′-neolignan(8), burselignan(9),(-)-evofolin B(10), icariol A2(11), ciwujiatone(12), and(+)-4″,4■-dihydroxy-3,3′,3″,3■,5,5′-hexamethoxy-7,9′;7′,9-diepoxy-4,8″;4′,8■-bisoxy-8,8′-dineolignan-7″,7■,9″,9■-tetraol(13). Compound 1 was a new compound, and compounds 1-13 were isolated from Agrimonia plant for the first time. This study can enrich the chemical components in A. pilosa and provide material conditions for the follow-up study of its biological activity and the elucidation of its pharmacodynamic substances.
