Comparative Phytochemical Investigation and Determination of Total Phenols and Flavonoid Concentration in Leaves and Flowers Extract of Delonix regia (Boj. Ex. Hook)
Medicinal plants are the potent source of biologically active compounds and have always been of field of interest for the effective chemotherapeutic agents and offering a broad spectrum of activity with greater emphasis on preventive action. The objective of the present study was to evaluate the phytochemical constituents, total phenol and total flavonoids content in leaves and flowers different extract of Delonix regia. Qualitative analysis of various phytochemical constituents and quantitative analysis of total phenolics and flavonoids were determined by the well-known test protocol available in the literature. Quantitative analysis of phenolic and flavonoids was carried out by Folins Ciocalteau reagent method and aluminium chloride method respectively. Phytochemical analysis revealed the presence of phenols, flavonoids, alkaloids and carbohydrate. The present study concluded that the crude extract of Delonix regia is a rich source of secondary phytoconstituents which impart significant antioxidant potential. It is expected that the important phytochemical properties recognized by our study in the indigenous medicinal plants will be very useful in the curing of various diseases when taken along with our food.
