盐胁迫对芝麻萌发过程中活性成分、抗氧化性及抗氧化酶活性的影响
TS210.1; 为探究盐胁迫对芝麻萌发的影响,以氯化钠和氯化钙混合盐溶液为培养液,对芝麻萌发过程中生长特性、总酚总黄酮含量、抗氧化能力和抗氧化酶活性的变化规律及其相关性进行分析.结果显示盐胁迫能够促进芝麻发芽,总酚、总黄酮积累,提高ABTS+自由基清除率和铁离子还原能力.盐胁迫对芝麻抗氧化酶活性起到了不同程度的诱导作用,并且对SOD和CAT活性的促进作用大于对APX和POD的作用.相关分析表明,盐胁迫下芝麻芽的总酚积累量与总黄酮、ABTS+自由基清除率、铁离子还原能力、POD酶活性呈极显著正相关,总酚与铁离子还原能力,SOD活性与DPPH、羟自由基清除能力,POD活性与铁离子还原能力的相关性...

| Abstract_FL | To investigate the effect of salt stress on the germination of sesame,a mixed salt solution of sodium chloride and calcium chloride was used as the culture medium to analyze the changes and correlations in growth characteristics,total phenolic content,total flavone content,antioxidant capacity,and antioxidant enzyme activity during the germination process of sesame.The results showed that salt stress could promote sesame germination and the accumulation of phenol and flavone,and improve the ABTS+free radicals scavenging rate and the iron ion reduction ability of sesame.The effect of salt stress on antioxidant enzyme activity varied by enzyme species,and the treatment had a more obvious promoting effect on SOD and CAT activities compared with APX and POD activities.The correlation analysis results demonstrated that the total phenol of sesame cultured under salt stress was positively correlated with its total flavonoids,ABTS+free radical scavenging rate,iron ion reducing ability,and POD enzyme activity.The correlation between total phenol and iron ion reducing ability,SOD activity and DPPH and hydroxyl radical scavenging ability,POD activity and iron ion reducing ability of sesame was enhanced by salt stress treatment.This study could lay a foundation for further deciphering the physiological mechanism of salt stress on sesame germination,and provide theoretical basis for the development of sesame functional foods. |
