中文摘要:

谷胱甘肽过氧化物酶(GSH-Px)是细胞内自发或酶促反应的活性调节剂,反映了机体清除氧自由基的能力,对其资源的开发和利用有重要意义。用直接测定法测定茄子、辣椒、番茄、马铃薯和枸杞等茄科植物中谷胱甘肽过氧化物酶活性,其中以马铃薯块茎、茄子果实及根的活性较高。这一结果为今后在茄科植物中该酶的进一步研究奠定了实验基础。

英文摘要:

Glutathione peroxidase(GSH-Px) is the regulator for spontaneously arise intracellular or was controlled by enzymatic reaction.It responses to the body’s ability to scavenge oxygen free radicals,and it contains important significance in resources development.The activity of Glutathione peroxidases were detected with dlrectly-determined method in eggplant,cayenne pepper,love apple,Irish potato,medlar of Solanaceae plants.The results showed that,the activities of the enzyme in the tuber of Irish potato and the fructification and root of eggplant were higher than that of the others,which will lay a foundation for the research of the enzyme in future.
