【目的】研究小黄椰果实发育过程中椰子胚乳的抗氧化能力,为鲜食或加工用椰子果实的筛选提供理论参考。【方法】在小黄椰果实发育过程中取不同发育期椰子胚乳,分别测定椰子胚乳中的超氧化物歧化酶(SOD)、过氧化物酶(POD)、过氧化氢酶(CAT)、谷胱甘肽还原酶(GR)活性及过氧化氢(H_2O_2)和可溶性蛋白含量,分析各指标的变化规律,评价不同成熟度椰子胚乳的抗氧化活性。【结果】液体胚乳的CAT、GR活性和H_2O_2含量高于固体胚乳,而SOD活性及可溶性蛋白含量低于固体胚乳。果实发育前期,固体胚乳的POD活性高于液体胚乳,而果实发育后期液体胚乳的POD活性高于固体胚乳。不同发育期中11月龄固体胚乳的SOD活性...

【Objective】To study the antioxidant capacity of coconut endosperm during the development of small yellow coconuts,and to provide a theoretical reference for the screening of fresh or processed coconut fruits.【Method】During the development of small yellow coconut fruit,coconut endosperm at different developmental stages were taken,and the superoxide dismutase(SOD)activity and peroxidase(POD)activity,catalase(CAT)activity,glutathione reductase (GR)activity,hydrogen peroxide(H_2O_2)content and soluble protein content in coconut endosperm were ...
