产地和果形对槟榔主要活性成分及抗氧化活性的影响

A Comparison of Main Active Components and Antioxidant Activity of Areca catechu L Fruits with Different Shapes from Different Habitats in Hainan

为了系统研究海南不同产地及果形槟榔的主要活性成分及抗氧化活性,采用比色法测定成熟槟榔青皮和种子的总生物碱和总黄酮含量,采用DPPH,ABTS和FRAP法测定其抗氧化能力,利用SPSS软件进行主成分分析和聚类分析,采用TOPSIS法进行综合评价。结果表明:不同产地的成熟槟榔,其形态指标及抗氧化能力明显不同,TOPSIS综合排序显示白石岭4(BSL4)的抗氧化能力最强;果实越饱满的槟榔,ABTS自由基清除能力越强。

Total alkaloids and total flavonoids content of the skin and seeds of the mature fruit of Areca catechu L. were determined by using colorimetric method to systematically study the main active ingredients and antioxidant activities of A. catechu L. fruit with different fruit shapes collected from different habitats in Hainan. The antioxidant capacity of the skin and seeds of the fruit was determined by using DPPH, ABTS and FRAP assays. SPSS software was used for principal component analysis and cluster analysis, and TOPSIS method was used for evaluation. The results showed that the morphological indicators and antioxidant capacity of mature A. catechu L. fruit from different habitats in Hainan were significantly different. The comprehensive ranking of TOPSIS showed that the fruit sample Baishiling 4 of A. catechu L. had the highest antioxidant capacity and that the fruit in full shape had a higher ABTS free radical scavenging capacity.
