| 摘 要： | 以银条为材料,探讨了银条根状茎中维生素C(VC)、抗坏血酸氧化酶(AAO)、超氧化物歧化酶(SOD)、过氧化物酶(POD)和多酚氧化酶(PPO)在其根茎膨大时期含量的积累变化。结果表明:在根茎开始膨大60d后,VC含量最高达61mg/100g;AAO酶活性在根茎膨大后30d达最大值0.147mg/g;SOD和POD酶活性在银条根茎膨大后75d达到最高值为9.05U/mg和13.60nmol.min-1.g-1;PPO在根茎膨大过程中出现上升-下降-上升的趋势。 |

| Abstract: | The variation of Vitamin C(VC)content,Ascorbic acid oxidase(AAO)activity,Superoxide dismutase(SOD) activity,Peroxidase(POD)activity and Polyphenol oxidase(PPO)activity were determined during Rhizome intumescences of Manyflower Betony.The results showed that a maximum of 61mg/100g of vitamin C content was obtained at 60 days after start swelling of roots.AAO activity in the roots was reached a maximum of 0.147mg/g at 30 days after swelling.SOD and POD activity was up to 9.05U/mg and 13.60nmol.min-1.g-1protein of their highest activity at 75 daysafter start swelling of root.In addition,the PPO activity exhibited a increased-decreased-increased change during the development root period.These findings may be providing a theoretical basis of scale production,development and utilization of nutrients for Manyflower Betony. |
