Abstract:

Acer truncatum leaves contain many bioactive substance,for example, flavonoid, chlorogenic acid, SOD enzyme, chlorophyll and MDA. The contents of bioactive substance in the two years of A. truncatum leaves under different covering treatment with variance analysis and the multi-comparison were determined.The results are as follows: The influence of the different covering treatment on the contents of bioactive substance in the leaves of A. truncatum is very obvious. The content of flavonoid treated under white plastic film is the highest, the contents of chlorogenic acid and chlorophyll treated under green plastic film are the highest. SOD activity and MDA content under red plastic film are the highest. Differences of the contents of flavonoid, chlorophyll and MDA under different covering treatment are significant at 1%; Differences of SOD activity and chlorogenic acid content are significant at 5%.

Key words: covering treatment, Acer truncatum, bioactive substance, content
