Antioxidant-phenolic content correlation of phenolics rich fractions from Dillenia suffruticosa wood bark

D illenia suffruticosa is one of the tropical medicinal plants that has been used traditionally for treating several diseases. However, phytochemical and pharmacological investigations D. wood bark have not well-investigated. This research aimed to investigate correlation between antioxidant properties total phenolic content phenolics rich extract fractions from . bark. The investigation revealed existence alkaloids in methanolic crude all fractions. Meanwhile, presence flavonoids was shown chloroform methanol highest demonstrated by fraction with 254.34 ± 16.86 mg GAE/g extract. flavonoid interestingly displayed 15.33 0.26 RE/g had a profound activity IC 50 values less than 15.63 ppm 8.83 ppm, respectively. A strong contents through analysis. Thus, could be considered potential natural source antioxidants.
