生物醫(yī)藥論文精品]絞股藍(lán)總皂苷的閃式提取及純化工藝研究-資料下載頁

2024-11-06 11:19本頁面

【導(dǎo)讀】絞股藍(lán)皂苷具有明顯的抗腫瘤作用,并且對(duì)神經(jīng)、血液、循環(huán)、內(nèi)分泌系統(tǒng)和消化。血脂、血糖水平,增強(qiáng)機(jī)體免疫功能,并可防治二十多種癌癥及其它多種疾病[1]。將引入一種全新的提取方法――閃式提取法,與其它的提取工藝做比較。的純化方法也有不少報(bào)道,包括樹脂吸附法、溶劑萃取法等。本文針對(duì)提取和純化兩方面的?;ぃ?;氧化鎂;絞股藍(lán)全草。樣品處理將絞股藍(lán)全草剪成2mm大小。即得濃度為2mg/mL的標(biāo)準(zhǔn)品溶液。波長處的吸收度A值,結(jié)果見表1。結(jié)果表明,當(dāng)取樣量在~,人參。皂昔Rb1含量與吸收度A值呈良好的線性關(guān)系。精密稱取絞股藍(lán)總皂苷10mg置5mL容量瓶中,加甲醇溶解并稀釋至刻度,搖勻。乙醇回流提取精密稱取絞股藍(lán)粉末20g置500mL圓底燒瓶中,加8倍量70%乙醇,沸水回流提取3次,每次2h,合并提取液,抽濾,減壓回收干燥[4]。
