人参(Panax ginseng C. A. Meyer.)是我国传统名贵中草药,具有极高的药用价值和广泛的药理作用。本论文主要通过现代分离纯化技术、分析鉴定技术及多水平活性检测技术对人参中研究较少但活性多样的生物大分子-蛋白及多肽进行生物特性研究,为优化人参的炮制加工工艺,揭示人参的临床物质基础,开发创新药物、保健食品等系列产品提供科学依据及技术支持。
1、采用PAGE电泳胶内酶活染色方法,对园参(鲜参、生晒参)、山参及林下参中氧化还原酶、水解酶、转移酶、裂解酶、异构酶等5种酶系共22种酶进行活性研究。结果表明,四种参中共有13种酶具有清晰酶活性谱带,其中,鲜参11种,生晒参8种,山参9种,林下参7种。过氧化物酶(POD)、过氧化氢酶(CAT)、苹果酸脱氢酶(MDH)、超氧化物歧化酶(SOD)、酯酶(EST)、酸性磷酸酶(ACP)、淀粉酶(AMY)7种酶为四种参共有,乳酸脱氢酶(LDH)、细胞色素氧化酶(CYT)、谷草转氨酶(GOT)3种酶仅为鲜参所有,磷酸葡萄糖变位酶(PGM)和葡萄糖磷酸异构酶(GPI)仅为山参所有,磷酸葡萄糖脱氢酶(PGD)为生晒参和鲜参共有。四种参酶活性的差别,...
【英文摘要】
Ginseng(Panax ginseng C. A. Meyer.) is a traditional Chinese herbal medicines and it has high medicinal value and wide range of pharmacological effects. In this study, we conducted experiments on macromolecules of which had varied activities while not being further studied. The biological activity of these macromolecules-namely ginseng proteins and peptides, had been tested via modern separation and purification technology, analysis and identification technology and detection of activity in vitro and...
