小叶爬崖香中苷类化合物的研究

Study of glycosides from Piper sintenense Hatusima

  • 摘要: 为探究胡椒属植物小叶爬崖香(Piper sintenense Hatusima)中苷类化学成分,采用硅胶、ODS、MCI GEL CHP20P、Sephadex LH-20柱色谱和半制备高效液相等色谱技术,从小叶爬崖香95%乙醇提取物的正丁醇部位分离获得9个苷类化合物。根据理化性质及核磁共振数据,以上化合物被鉴定为(2S)-2-羟基-1-(4-羟基-3-甲氧基苯基)-1-丙酮-2-O-β-D-葡萄糖苷(1)、苯乙醇-β-D-葡萄糖苷(2)、苄醇-β-巢菜糖苷(3)、苄醇-β-樱草糖苷(4)、苯乙醇-β-D-呋喃芹菜糖基-(1''→2')-β-D-葡萄糖苷(5)、红景天苷(6)、苯乙醇-β-樱草糖苷(7)、(顺)-3-己烯醇-β-巢菜糖苷(8)、(顺)-3-己烯醇-β-樱草糖苷(9)。其中化合物1为新化合物,化合物3~9为首次从胡椒属中分离得到。

     

    Abstract: In order to investigate the chemical constituents of glycosides in Piper sintenense Hatusima, column chromatographic techniques such as silica gel, ODS, MCI GEL CHP20P, Sephadex LH-20, and semi-preparative high performance liquid chromatography were used to afford nine glycosides from the n-butanol part of the 95% ethanol extract of Piper sintenense Hatusima. Based on the physicochemical properties and NMR data, the above compounds were identified as (2S)-2-hydroxy-1-(4-hydroxy-3-methoxyphenyl)-1-propanone-2-O-β-D-glucopyranoside (1), 2-phenylethyl β-D-glucopyranoside (2), benzyl α-L-arabinopyranosyl-(1''→6')-β-D-glucopyranoside (3), benzyl β-D-xylopyanosyl-(1''→6')-β-D-glucopyranoside (4), phenethyl β-D-apiofuranosyl-(1''→ 2')-β-D-glucopyranoside(5), salidroside (6), phenethanol β-D-xylopyanosyl-(1''→6')-β-D-glucopyranoside (7), (Z)-hexenyl-O-α-L-arabinopyranosyl-(1''→6')-O-β-D-glucopyranoside (8), (Z)-hexenyl-O-β-D-xylopyanosyl-(1''→6')-O-β-D-glucopyranoside (9). Compound 1 was identified as a new compound, and compounds 3-9 were isolated from the genus Piper for the first time.
