摘  要:
本实验分别运用有机溶剂萃取法和大孔吸附树脂分离法对肉苁蓉苯乙醇苷(PEG)粗提液进一步分离纯化。通过比较分析确定合适的分离纯化方法;并对经分离纯化的苯乙醇苷从还原能力、1,1-二苯基苦基苯肼(DPPH)自由基清除能力和亚油酸体系抗脂质过氧化能力三方面进行抗氧化活性评价研究。结果表明:D101大孔吸附树脂柱层析较适合苯乙醇苷的纯化工艺,苯乙醇苷抗氧化活性高于阳性对照VE。

摘  要:
Organic solvent extraction and D101 macroporous absorption resin chromatography were used to purify phenylethanoid glycosides (PEG) from Cistanche salsa, and the antioxidant activity of phenylethanoid glycosides was assessed by reducing power, DPPH radical-scavenging capacity and ferric thiocyanate (FTC) method. The results indicated that D101 macroporous absorption resin chromatography is more suitable for the purification of phenylethanoid glycosides, and the obtained phenylethanoid glycosides exhibit stronger antioxidant capacity compared with the positive control vitamin E.
