摘要
该研究采用ABTS,DPPH和FRAP 3种方法,考察酸枣仁与茯苓共发酵过程中体外抗氧化活性的变化规律,结合活性成分含量和^(1)H-NMR技术探讨茯苓发酵酸枣仁的抗氧化活性增强机制。结果表明发酵过程可显著提高酸枣仁总酚、总皂苷、总多糖等活性成分含量。^(1)H-NMR代谢组学研究表明,酸枣仁发酵后亮氨酸、赖氨酸、缬氨酸、丙氨酸等氨基酸,肌酸、肌酸酐、甜菜碱等含氮化合物,酸枣仁皂苷A、斯皮诺素等次级代谢产物均显著增加,皮尔逊相关分析表明上述成分与抗氧化活性呈现正相关性,推测酸枣仁发酵后抗氧化活性增强可能是多种化学成分共同作用的结果。该研究初步阐明了酸枣仁发酵后抗氧化活性增强的机制,为酸枣仁-茯苓共发酵产物的开发与利用提供新的研究思路。
In this study,the antioxidant property changes in fermented Ziziphi Spinosae Semen(FZSS)with Poria cocos were analyzed by DPPH,ABTS and FRAP methods.Then the content determination of active ingredients and 1H nuclear magnetic resonance(^(1)H-NMR)spectroscopy were also used to investigate the mechanism of FZSS with P.cocos in enhancing the antioxidant activity.The results showed that the content of active ingredients such as total phenols,total saponins and total polysaccharides were significantly increased during the fermentation time.The results of^(1)H-NMR metabonomics showed that the contents of amino acids such as leucine,lysine,valine and alanine,nitrogen compounds such as creatine,creatinine,and betaine,and secondary metabolites,for instance,jujuboside A and spinosin were higher after fermentation,and above components showed positive correlation with antioxidant capacity in Pearson correlation analysis.Therefore,it was inferred that the enhancement of antioxidant activity of FZSS may be the result of the joint action of various chemical components.This study preliminarily clarified the mechanism of FZSS in enhancing the antioxidant activity,and provided new research ideas for the product development and utilization of FZSS.
