| 摘 要： | 研究大果榕果实的多酚含量及其抗氧化活性、α-葡萄糖苷酶和乙酰胆碱酯酶抑制活性,为其进一步开发利用奠定基础。以采自海南保亭七仙岭的大果榕果实为实验材料,用体积分数65%的乙醇提取大果榕果实多酚,采用Folin-酚法测定总酚含量。对获得的大果榕果实多酚进行1,1-二苯基-2-三硝基苯肼(1,1-diphenyl-2-picrylhydrazyl,DPPH)自由基、2,2’-联氮双(3-乙基苯并噻唑啉-6-磺酸)二铵盐(2,2’-azinobis-(3-ethylbenzthiazoline-6-sulphonate),ABTS)自由基、羟自由基(·OH)清除率以及α-葡萄糖苷酶抑制活性和乙酰胆碱酯酶抑制活性测定。结果表明:大果榕果实多酚含量较高,达1.92 mg/g(以干质量计),其对DPPH自由基、ABTS+·和·OH均具有显著的清除活性,且呈质量浓度依赖性,IC50值分别为141.25、91.20、45.71μg/m L;大果榕果实多酚对α-葡萄糖苷酶抑制活性强于阳性对照阿卡波糖,且呈现明显的质量浓度依赖性,IC50值为102.33μg/m L;同时大果榕果实多酚对乙酰胆碱酯酶也具有一定的抑制活性,IC50值为4.9 mg/m L。研究结果表明大果榕果实多酚具有良好的抗氧化性、α-葡萄糖苷酶抑制活性和一定的乙酰胆碱酯酶抑制活性。

| Abstract: | Total phenolics were extracted from Ficus auriculata fruits using 65% ethanol and quantified by the Folin phenol
method. The antioxidant activity of the ethanol extract was assessed by DPPH, ABTS and hydroxyl radical scavenging
assays and its inhibitory activity against alpha-glucosidase and acetylcholine esterase was also evaluated. Results showed
that the fruit extract contained high levels of total phenolics (1.92 mg/g DW) and could scavenge DPPH, ABTS and hydroxyl
radicals effectively in a concentration dependent manner with IC50 of 141.25, 91.20 and 45.71 μg/mL, respectively. It also
exhibited strong inhibitory activity against α-glucosidase in a concentration dependent manner with IC50 of 102.33 μg/mL.
Similarly, it showed inhibitory activity against acetylcholine esterase with IC50 of 4.9 mg/mL. Therefore, the polyphenolrich
extract from Ficus auriculata fruits has strong antioxidant potential and inhibitory activity against α-glucosidase and
acetylcholine esterase. |
