| 摘 要： | 对安吉白茶春季返白过程中保护性酶活力及其生化成分的变化作了检测，结果表明，安吉白茶 芽梢在早春返白过程中，过氧化物酶（ＰＯＤ）活力升高，而超氧化物歧化酶（ＳＯＤ）、过氧化氢酶（ＣＡＴ）活 力降低；脂质过氧化产物丙二醛（ＭＤＡ）、叶绿素（ＣＨ）、儿茶素、咖啡因等含量则下降，芽梢复绿后，ＰＯＤ 活力降低，ＣＡＴ，ＳＯＤ 活力回升；叶绿素，ＭＤＡ，儿茶素和咖啡固含量也上升。

| Abstract: | The changes of physiological and biochemical characters during stage albescent process of Anji Baicha were studied. The results showed that peroxidase. (POD) activity increased with stage albescent process, the activities of superoxide dismutase (SOD) and catalase (CAT) dropped sharply, and that the formation of malondialdehyde (MDA) decreased. The reductions of the contents of chlorophyll (Ch1) , catechin and caffeine were also found. When the leaves returned to green automatically, the activity of POD dropped , and the activities of SOD and CAT increased. MDA formation and contents of Ch1 , cate- chin and caffeine also increased. |
