随着分子生物学技术在中药学领域的渗透与发展,以DNA分子为标记的中药分子鉴定方法得到不断的发展与应用,DNA分子特征作为遗传标记进行中药鉴别更为准确可靠.本文介绍了鉴定中药正品和混淆品的RAPD指纹库以及不同产地的同种药材的鉴定;然后阐述了亲缘关系药材的研究和鉴定方法;最后说明了DNA分子标记技术则可在分子水平上利用DNA指纹图谱的差异以及基因序列间的变异位点的多少将道地与非道地药材区别开来,从而为优良品种的选取和栽培提供分子依据,增强了用药的安全性和效能。

本文通过Alcalase蛋白酶和Protamex蛋白酶对灵芝蛋白提取液进行水解并对水解前后的灵芝蛋白的抗氧化活性进行了研究.研究结果表明,灵芝蛋白提取液与酶解液均具有抗氧化活性,随着灵芝蛋白浓度增加,蛋白提取液清除·oH自由基的能力和还原力都增强,当灵芝蛋白的浓度为0.28mg/mL时,蛋白提取液的·OH自由基清除率为28.7%,且清除·OH自由基的能力与灵芝蛋白的浓度的关系可以用对数方程来描述.
目的:研究峨眉桃叶珊瑚果实中桃叶珊瑚苷的提取纯化工艺.方法:以提取率为指标,采用单因素法考察峨眉桃叶珊瑚果实中桃叶珊瑚苷醇提工艺;以纯度和回收率为指标,考察桃叶珊瑚苷的硅胶柱色谱法及结晶法纯化工艺.结果:桃叶珊瑚苷的最佳提取条件:以80%乙醇为溶剂,料液比1:10,提取温度80℃,回流提取3次,1.0h/次;硅胶柱色谱纯化工艺:以甲醇-氯仿(1∶5和1∶3)梯度洗脱,洗脱剂用量为3 BV,柱子径高
