摘要
以“满堂红”萝卜芽苗菜为试材,采用水培方式,探究不同浓度硒对萝卜芽苗菜抗氧化性及相关成分含量的影响,并对抗氧化能力与相关成分含量进行相关性分析。结果表明:DPPH值、可溶性蛋白、可溶性糖、Vc含量均随硒处理浓度的增加呈先升高后降低再升高的趋势。当硒处理浓度为5 mg/L时,萝卜芽苗菜中花青素、Vc、SOD活性、抗氧化能力和生物量均达最大值。萝卜芽苗菜中的硒含量和POD活性显著增加,分别为未处理组的21.45倍和1.40倍;MDA含量显著降低,为未处理组萝卜芽苗菜中MDA的77.58%。相关性分析表明,萝卜芽苗菜的ABTS值与其所含的SOD活性、DPPH值与其所含的花青素含量、FARP值与与其所含的Vc含量分别成显著正相关。适量浓度的硒处理可促进萝卜芽苗菜生物量和总硒量的积累,并能有效增强抗氧化能力并提高其营养品质。
In order to explore the effect of different concentrations of selenium on the antioxidant activity and the content of related components of radish sprouts,"Man tang hong"radish sprouts were cultured as test materials by hydroponics method,and the correlation between antioxidant ability and the content of related components in the radish sprouts was analyzed as well.The results showed that DPPH value,soluble protein,soluble sugar and Vc contents were firstly increased,then decreased and then increased with the increase of selenium treatment concentration.When 5 mg/L Se was applied,the biomass,anthocyanin content,Vc content,SOD activity and antioxidant capacities were the highest in the treated radish sprouts.Selenium content and POD activity were significantly increased in the treated radish sprouts,which was 21.45 and 1.40 times of the untreated group,respectively.MDA content was significantly reduced to 77.58%of MDA of the untreated group.The correlation analysis showed that ABTS had a strong correlation with SOD activities of the radish sprouts,DPPH had a strong correlation with the content of anthocyanin in the radish sprouts,and FARP had a strong correlation with the content of Vc in the radish sprouts.Proper concentration of selenium treatment could promote the accumulation of biomass and total selenium in radish sprouts,effectively enhanced the sprouts’antioxidant capacity and improved the sprouts’nutritional quality.
