目的 对土牛膝总皂苷进行体内外抗炎活性与分离鉴定研究,为其治疗炎症提供实验依据.方法 采用十八烷基硅烷键合硅胶-AQ柱色谱法(ODS-AQ)纯化制备土牛膝总皂苷;建立氨水诱导的急性咽炎大鼠模型,灌胃给药评价粗毛牛膝提取物及总皂苷抗炎活性;采用柱层析、核磁共振谱、质谱等技术对土牛膝总皂苷中的主要化合物进行分离、纯化和结构鉴定;建立脂多糖诱导的巨噬细胞炎症模型,评价各皂苷单体化合物的抗炎活性.结果 制备的粗毛牛膝总皂苷含量达到81.8％;在急性咽炎大鼠模型中,粗毛牛膝总皂苷及水煎液具有良好抗炎疗效,能显著降低血清IL-6、IL-1β、TNF-α细胞因子水平;总皂苷中鉴定出6个齐墩果烷型三萜皂苷,分别为竹节参皂苷Ⅳa(1)、竹节参皂苷Ⅳa丁酯(2)、金盏花皂苷E(3)、金盏花皂苷E 丁酯(4)、竹节参皂苷Ⅱ(5)、竹节参皂苷V(6);体外炎症模型表明,分离得到的三萜皂苷类单体化合物均有不同程度的抗炎作用.结论 首次系统证明了皂苷类成分是粗毛牛膝发挥抗炎活性的药效物质基础;从牛膝属植物中首次分离得到化合物2和4,并证实其具有抗炎作用.
Extraction,composition identification,and anti-inflammatory activity of total saponins from Achyranthes aspera L.
Objective To study the in vivo and in vitro anti-inflammatory activity,as well as isolation and identification of total saponins from Achyranthes aspera L.,providing experimental evidence for its treatment of inflammation.Methods The total saponins of Achyranthes aspera L.were purified and prepared by ODS-AQ;after modeling of ammonia-induced acute pharyngitis,rats were treated with corresponding drugs by gavage to evaluate the anti-inflammatory activities of the extract and total saponins of Achyranthes aspera L;column chromatography,nuclear magnetic resonance spectroscopy(NMR),mass spectrometry(MS),and other techniques were used to isolate,purify,and identify the main compounds in the total saponins of Achyranthes aspera L.;a lipopolysaccharide-induced macrophage inflammation model was established to evaluate the anti-inflammatory activity of various saponin monomers.Results The prepared total saponins of Achyranthes aspera L.reached a content of 81.8％;in the acute pharyngitis rat model,the total saponins and aqueous extract of Achyranthes aspera L.showed good anti-inflammatory effects,significantly reducing the serum levels of IL-6,IL-1β,and TNF-α;six oleanane-type triterpenoid saponins were identified as chikusetsusaponin Ⅳ a(1),chikusetsusaponin Ⅳ a butyl ester(2),calendulaside E(3),calendulaside E butyl ester(4),chikusetsusaponin I(5),and chikusetsusaponin V(6).In vitro inflammation model indicated that the isolated triterpenoid saponin monomers all exhibited varying degrees of anti-inflammatory effects.Conclusion This paper systematically demonstrates for the first time that saponin components are the pharmacological material basis for the anti-inflammatory activity of Achyranthes aspera L..Compounds 2 and 4 with anti-inflammatory effects are ester first isolated from Achyranthes plants
