中文摘要:研究了亨氏马尾藻95%乙醇提取物不同溶剂级分的体外抗氧化活性。采用Folin-Ciocalteu法测定亨氏马尾藻醇提取物(总提取物)以及石油醚萃取物、乙酸乙酯萃取物、正丁醇萃取物和水萃取物五个部位的总酚含量,并通过DPPH·、ABTS^+·清除及ORAC三种方法评价五种提取物的抗氧化活性。结果表明,乙酸乙酯萃取物的总酚含量最高,为(12.71±0.02)mg GAE/g(没食子酸当量)。在不同抗氧化测定方法中,亨氏马尾藻醇提取物及其不同溶剂萃取物均表现出不同程度的抗氧化活性。其中,乙酸乙酯萃取物抗氧化活性较强,其DPPH和ABTS半数清除率分别为(0.89±0.01)mg/m L和(0.73±0.03)mg/m L,ORAC值达到(1803.78±81.37)μmol TE/g。
外文摘要:In this research,antioxidant activitiy of different fractions from ethanol crude extracts of S. henslowianum was investigated in vitro. The total phenolic contents of the 95% ethanol crude extracts and their four solvent fractions( viz.,petroleum ether( PE),ethyl acetate( EA),n- butanol and aqueous) were determined by Folin-Ciocalteu,and their antioxidant properties were evaluated using three assays including 1,1- Diphenyl- 2-picrylhydrazyl radical 2,2- Diphenyl- 1-( 2,4,6- trinitrophenyl) hydrazyl( DPPH),2,2'- Azinobis-( 3-ethylbenzthiazoline-6- sulphonate( ABTS) radical scavenging and oxygen radical absorbance capacity.The results showed that EA fraction had the highest content of total phenolics( 12.71 ± 0.02 mg gallic acid equivalents / g). All five fractions from S. henslowianum exhibited the antioxidant activity. EA fraction exhibited strongest antioxidant activities among all the fractions,which the values of IC_(50) based on DPPH· and ABTS+·were( 0.89 ± 0.01) mg /m L and( 0.73 ± 0.03) mg / m L respectively,and the values of ORAC was( 1803.78 ± 81.37) μmol Trolox equivalents / g.
