槟榔籽中抗氧化活性物质的分离与结构分析

摘要

为了研究槟榔籽中的抗氧化活性物质,通过柱色谱法分离纯化槟榔籽乙醇提取物,结合抗氧化活性筛选,分离得到槟榔籽中主要的抗氧化活性物质Fr-4。利用高效液相色谱分析其纯度,经波谱分析确定该物质为表儿茶素。%In order to research the antioxidant activity compounds of the betel nut seed,the ethanol extract of betel nut seed was isolated and purified by column chromatography.Combined with antioxidant activity screening,Fr-4 was isolated as the main antioxidant activity compounds of betel nut seed.HPLC was used to analyze its purity and epicatechin was identified by spectrum analysis.
