摘要
探讨不同年份萝卜菜圃的活性物质分析及抗氧化活性分析,并对二者进行相关性分析,采用超声辅助提取法对萝卜菜圃中的活性物质进行提取,并用紫外分光光度法测定不同年份萝卜菜圃的黄酮、多酚、多糖及抗氧化值。结果显示,黄酮、多酚、多糖含量随着年份的增加呈递增趋势;黄酮、多酚、多糖、·OH清除率及ABTS^(+)·清除率从高到低均依次为储存10年处理组>储存5年处理组>储存1年处理组,DPPH·清除率呈递减趋势,还原力呈线性关系,黄酮、多酚和多糖含量分别与其抗氧化能力呈显著的相关性(p<0.05)。结果显示,存放年限越高,对于萝卜菜圃的品质和抗氧化活性均有良好的作用。
This experiment explored the analysis of active substances and antioxidant activity of preserved vegetables from different years,and conducted correlation analysis between the two.The active substances in preserved vegetables were extracted using ultrasound assisted extraction method,and the flavonoids,polyphenols,polysaccharides,and antioxidant values of preserved vegetables from different years were measured using UV spectrophotometry.The results showed that the content of flavonoids,polyphenols,and polysaccharides showed a decreasing trend with the increase of years;the clearance rates of flavonoids,polyphenols,polysaccharides,·OH,and ABTS^(+)·clearance rates from high to low were as followed:storage for ten years treatment group>storage for five years treatment group>storage for one year treatment group.The DPPH·clearance rate showed a decreasing trend,and the reducing power showed a linear relationship.The content of flavonoids,polyphenols,and polysaccharides was significantly correlated with their antioxidant capacity(p<0.05),indicating that the longer the storage period,Overall,it had a good effect on the quality and antioxidant activity of preserved vegetables.
