目的 研究土庄绣线菊Spiraea pubescens的化学成分。方法 采用硅胶柱色谱、ODS柱色谱和制备HPLC等技术进行化学成分分离,根据理化性质和波谱数据鉴定化合物结构。结果 从土庄绣线菊乙醇提取物中分离得到14个化合物,分别鉴定为β-谷甾醇(1)、正二十三醇(2)、4-豆甾烯-3-酮(3)、正二十五醇(4)、豆甾烷醇(5)、(+)-环橄榄素(6)、(+)-africannal(7)、(+)-南烛木树脂酚(8)、5-甲氧基-(+)-异落叶松脂素(9)、(+)-异落叶松脂素(10)、(7R,8R)-4,7,9,9'-四羟基-3,3'-二甲氧基-8-O-4'-新木脂素(11)、(6S,9R)-6-羟基-3-酮-α-紫罗兰醇-9-O-β-D-吡喃葡萄糖苷(12)、(+)-南烛木树脂酚9-O-β- D-吡喃木糖苷(13)、(-)-南烛木树脂酚9-O-β-D-吡喃木糖苷(14)。结论 化合物2~5 、7~14 为首次从绣线菊属植物中分离得到,化合物1 和6 为首次从该植物中分离得到。

Objective To investigate the chemical constituents from the ethanol extract of Spiraea pubescens. Methods The compounds were isolated and purified by chromatography on silica gel, ODS, and preparative HPLC. Their structures were elucidated on the basis of chemical and spectroscopic methods, including MS, 1D, and 2D NMR spectral techniques. Results Fourteen compounds were isolated and identified as β-sitosterol (1), tricosyl alcohol (2), stigmast-4-en-3-one (3), pentacosyl alcohol (4), stigmastanol (5), (+)-cyclo-olivil (6), (+)-africannal (7), (+)-lyoniresinol (8), 5-methoxy-(+)-isolariciresinol (9), (+)-isolariciresinol (10), (7R,8R)-4,7,9,9'-tetrahydroxy-3,3'-dimethoxy-8-O-4'-neolignan (11), (6S,9R)-6-hydroxy-3-one-α-ionol-9-O-β-D-glucopyranoside (12), (+)-lyoniresinol 9-O-β-D-xylopyranoside (13), and (-)-lyoniresinol 9-O-β-D-xylopyranoside (14). Conclusion Compounds 2-5 and 7-14 are isolated from the plants of Spiraea L. for the first time, and compounds 1 and 6 are obtained from this plant for the first time.
