n.抗壞血酸鹽

Ascorbate oxidase from Cucurbita spec. 抗壞血酸氧化酶。

Contents of titrable acids and ascorbate acid were the highest after two weeks of storage and then decreased. 可滴定酸及抗壞血酸含量在采后兩周內呈上升趨勢，兩周后下降。

Ascorbate peroxidase and glutathione reductase activities in SA-treated fruit were significantly greater than those in controls during cold storage. 在貯藏和貨架期結束時，抗壞血酸氧化酶和谷胱甘肽還原酶活性顯著高于對照。

Superoxide dismutase (SOD),ascorbate peroxidase (ASA-POD),catalase (CAT) and the content of MDA were determined after 7 days. 培養(yǎng)7天后測定超氧化物歧化酶(SOD)、抗壞血酸過氧化物酶(ASA-POD)、過氧化氫酶(CAT)活性和丙二醛(MDA)含量。

On the other hand, SOD, APX, GPX, CAT activities and ascorbate (AsA, DAsA) content, glutathione (GSH, GSSG) content increased under high temperature stress. 另一方面，葉片中的抗氧化酶，包括超氧化物歧化酶(SOD)、抗壞血酸過氧化物酶(APX)、愈創(chuàng)木酚過氧化物酶(GPX)、過氧化氫酶(CAT)的活性以及抗壞血酸(AsA，DAsA)和谷胱甘肽(GSH、GSSG)等抗氧化劑的含量在高溫脅迫下明顯升高；
