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 61 mg/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 0.147 mg/g at 30 days after swelling.SOD and POD activity was up to 9.05 U/mg and 13.60 nmol?min-1?g-1 protein of their highest activity at 75 days after 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.
