摘  要:
本文主要探究两种灵芝粗多糖提取及抗氧化活性的比较。采用超声波提取,然后,选用苯酚——硫酸法检测两种灵芝粗多糖得率。其中紫芝为2.2%,赤芝为2.8%。另外,还选取了铁氰化钾还原法来检测比较两种灵芝粗多糖的自身还原能力,同时对二者清除羟基自由基(-OH)效果进行了比较,以及对清除DPPH的效果进行比较,结果表明:赤灵芝粗多糖清除羟基自由基的能力、还原能力均比紫灵芝粗多糖强,但是对于DPPH的清除能力比紫芝粗多糖稍弱,而且紫芝、赤芝的抗氧化活性均与其粗多糖含量的浓度成正比。

摘  要:
In this paper, the extraction and antioxidant activity of crude polysaccharides from Ganoder-ma lucidum were studied. Ultrasonic extraction was used, then phenol-sulfuric acid method was used todetect the yield of two kinds of crude Ganoderma lucidum polysaccharides.The scavenging effect of hy-droxyl radical(-OH) was compared, and the effect of scavenging DPPH was compared. The resultsshowed that crude polysaccharide of Ganoderma lucidum could scavenge hydroxyl radical and reducehydroxyl radical more effectively than crude polysaccharide of Ganoderma lucidum, but for DPPH.
