绿升麻中菠萝蜜烷型三萜类成分研究
目的 研究绿升麻中菠萝蜜烷型三萜皂苷类化学成分.方法 以硅胶柱层析、凝胶层析等多种柱层析分离,制备高效液相色谱纯化,得到单体化合物,以各种有机波谱鉴定化合物结构.结果 分离得到15个菠萝蜜烷型三萜类皂苷化合物,鉴定为asiaticoside A (1);asiaticoside B (2);26-deoxycimicifugoside(3);cimicifugoside(23S,4);25-甲氧基升麻醇-3-O-b-D-木糖苷(25- O-methyl-cimigenol-3-O- b-D-xylopyranoside,5);25, 2'-二乙酰升麻醇-3-O-β-D-木糖苷(25,2'-O-diacetylcimigenol-3-O-β-D-xylopyranoside,6);24-乙酰升麻醇-3-O-β-D-木糖苷(24-O-acetylshengmanol-3-O-β-D-xylopyranoside(23R,24R,7);24-O-acetyldahurinol-3-O-β-D-xylopyranoside(8);23-乙酰升麻醇-3-O-β-D-木糖苷(23-O-acetylshengmanol-3-O-β-D-xylopyranoside,9);Cimiracemoside M (10);12β-acetoxy-3β-hydroxy-24,25,26,27-tetranor-cycloart-7-en-23,16β-olide-3-O-β-D-xylopyranoide(11);12β-acetoxy-3β-hydroxy-24,25,26,27-tetranor-cycloartan-23,16β-olide-3-O-β-D-xylopyranoide(12);Cimiracemoside H(13);Neocimicigenosides B(14) ;2'-O-乙酰基-25-脱水升麻醇-3-O-β-D-木糖苷 (2'-O-acetyl-25-anhydrocimigenol-3-O-β-D-xylopyranoside, 15).结论 菠萝蜜烷型三萜类皂苷化合物3～15均为首次从绿升麻中分离得到.
