Abstract: Quantitative evaluation for foliar pigments, nutrients, flavonoids, polyphenol and antioxidant activities of Gynura procumbens (Lour).Merr.was done on three different growing seasons within a year.A pot culture based experiment was conducted during February, 2017 to January, 2018 at the Botanical Garden of Chittagong University.Maximum foliar photosynthetic pigments, nutrients, polyphenol were observed in monsoon (June-August) and minimum in late monsoon (September-November) respectively.Whilst the highest flavonoids content was determined in the leaf extract of early monsoon (March-May) and the lowest in late monsoon (September-November) respectively.Furthermore, the maximum antioxidant activity was estimated in the leaf extract of late monsoon (September-November) and the lowest in early monsoon (March-May) respectively.The present study concludes that monsoon (June-August) is suitable for efficient photosynthesis, nutrient as well as polyphenol accumulation in Gynura and early monsoon (March-May) is favourable for maximum flavonoid synthesis and late monsoon (September-November) is the right time for harvesting the leaves of Gynura to obtain maximum antioxidant activity for medicinal use.
