A study on seasonal variations of the bioactive constituents in the leaves of Acer truncatum


, : A study on seasonal variations of the bioactive constituents in the leaves of Acer truncatum. Journal of Northwest Forestry College 12(4): 68-71

Variations of the contents of flavonoids and chlorogenic acid were studied in the leaves of A. truncatum in China. The results showed that the content of chlorogenic acid reaches a peak (4.88%) in June, while for flavonoids it is in August (5.79%). Plants of different ages (1, 2, 5, 6, 15, 28 and 35 yr) were also tested.
