【摘要】:本课题对两种具有保健功能作用的中药-蒙古黄茜(Astragalus membranaceus(Fisch.)Bge.Var.Mongholicus(Bge.)Hisao)和栀子花(the flower of Gardenia jasmino idesEllis)的化学成分及初步的药理活性进行了研究。对蒙古黄芪根茎的70%乙醇提取物进行了较系统的化学成分分离及鉴定,从中得到十四个化合物,包括五个环菠萝蜜烷型三萜皂苷,即Astragaloside Ⅰ(1)、Astragaloside Ⅱ(2)、Isoastragaloside Ⅱ(3)、Isoastragaloside Ⅰ(4)、Astragal oside Ⅳ(5),两个羽扇豆烷型三萜羽扇豆酮(6)、白桦脂醇(7),四个黄酮类化合物(±)-10-甲氧基美迪紫檀素(8)、Isomucronulatol7-glueosid(9)、7,3 '-diohydroxy-5 '-methoxisofiavone(10)、毛蕊异黄酮苷(12),两个甾体类化合物β-谷甾醇(13)、胡萝卜苷(14),一个酰胺类化合物(2S,3S,4R,10E)-2-[(2R)-2-羟基二十四烷酰氨基]-10-十八烷-1,3,4-三醇(11)。从中可看出Cycloartane型三萜为其主要成分。对栀子花的95%乙醇提取物乙酸乙酯萃取部位分离并鉴定了 11个化合物,包括九个Cycloartane型三萜类化合物以及两个环烯醚萜类化合物,其中三个为新的 Cycloartane 型裂环三萜,即 Dikamaliartane G(15),Dikamaliartane H(16),DikamaliartaneⅠ(17),一个已知的 Cycloartane型裂环三萜 DikamaliartaneD(18),两个已知的Cycloartane型三萜栀子花甲酸(19)和栀子花乙酸(20),三个已知的五环三萜熊果酸(21)、铁冬青酸(22)、3β-6β-23-trihydroxyolean-12-en-28-oic acid(23),以及两个已知的环烯醚萜Aglucone(24)和Cyclopenta(25)。对上述化合物通过多种波谱技术(核磁、质谱、红外等)进行了结构鉴定,并对这两味中药中的特征成分-Cycloartane型三萜进行的体外抗肝损伤药理活性研究,发现一些化合物表现出对H2O2诱导的HepG2细胞损伤的保护活性。本文的研究工作为进一步阐明这两种中药保健功能的物质基础提供了重要参考依据。
