中药商陆具有利水消肿,解毒散结的传统功效,在临床上多用于肾性、心源性和肝硬化腹水的治疗,但利尿的活性部位或成分却不明确。本课题采用天然药物化学和药理学结合的方法,拟探明商陆的利尿活性部位或成分,主要研究内容有:药材品种的生药鉴定;不同溶媒提取部位的制各;利尿药理实验筛选;药材及与利尿有关活性部位的HPLC图谱表征;商陆生物碱成分的提取分离;垂序商陆脂溶性成分的GC-MS分析。研究结果:初步筛选得到商陆利尿的活性部位为商陆粗生物碱与商陆粗皂苷的混合物;建立了商陆及与利尿相关活性部位的HPLC图谱;从商陆中分离得到两种生物碱单体成分;鉴定了8种脂溶性成分。
药材来源鉴定:中药商陆是指商陆科植物商陆(Phytolacca acinosa Roxb.)和垂序商陆(Phytolacca americana L.)两个品种来源的干燥根,据文献报道商陆与垂序商陆在化学成分、药理作用、毒性等方面均有很大的差异。因此,本文通过对药材性状鉴定,横切面及粉末的显微鉴定、特异性的理化鉴定反应和薄层色谱层析行为研究,实验结果与文献报道的垂序商陆性质一致,鉴定反应呈阳性,薄层层析与正...
【英文摘要】
Radix Phytolaccae has diuresis, decreasing swelling and detoxication, precluding knot traditional effects. It often cures Renal edema, Cardiogenic edema and Ascites of cirrhosis of liver in clinic. But now its effective part or components of diuresis has not been found. In this paper the methods of the natural pharmaceutical chemistry and pharmacology were used to search for diuretic effective part or components of Radix Phytolaccae. The main researches were aimed to identify the variety of the ...
