摘要: 本实验研究了石花菜醇提物的抑菌活性和抗氧化活性。采用生长速率法测定各相提取物的抑菌活性,结果表明石花菜含有丰富的抗病原真菌资源;采用水杨酸法和邻苯三酚法分别测定各相提取物对羟基自由基和超氧阴离子自由基的清除能力,结果表明石花菜有较强的抗氧化能力。同时对各相提取物进行了系统的化学成分定性检测,结果表明石花菜的生物活性可能与其中含有的海藻多糖、黄酮、甾体皂甙、内酯及香豆素等活性成分有关。

Abstract: The aim of this paper was to research the antifungal and antioxidant activities of Gelidium amansii. According to the results of mycelial growth of plant pathogenic fungi, Gelidium amansii had resourceful antifungal activities sources. The Gelidium amansii showed scavenging capacity to hydroxyl free radical generated by Fenton reaction and to superoxide anion generated by a pyrogallol autoxidation system. The active constituents might be seaweed polysaccharides, flavonoids, steroidal saponins, lactones and coumarins etc.

Key words: Gelidium amansii, antifungal activities, antioxidant activity, active constituents
