The study clearly indicates the presence of the Phytochemicals such as Tannin, Saponin, Flavonoids and Alkaloids present in the Plumeria rubra. Gallic acid Equivalent (GE) Total Phenols in the leaves and flowers were determined using Folin Ciocalteu method. The flavonoid content of the leaves and flowers were measured using UV- spectrophotometer. The antioxidant activity by DPPH method analysed and values were expressed as Ascorbic acid Equivalent Antioxidant Capacity (AECE).
