Phytochemical Study and Antioxidant Properties of Aqueous Extracts of Murraya paniculata Leaf

Aims: To investigate the chemical groups present, total phenolic compound, total flavonoid and to evaluate the possible antioxidant activity of aqueous extracts of Murraya paniculata leaf. Place and Duration of Study: Department of Applied Chemistry and Chemical Engineering Department, Noakhali Science and Technology University, Bangladesh, in 2017 Methodology: The dry leaves were boiled and extracted with water. The extracts were concentrated and then investigated for their total phenolic compound, total flavonoid, evaluated the antioxidant activity. The preliminary screening of the various extracts was carried out using standard methods. Total phenolic content (TPC) was determined by the modified Folin-Ciocalteu method, total antioxidant capacity (TAC) and total flavonoid content were measured according to the Phosphomolybdate-method and Dowd-method respectively. Results: The aqueous extract showed good antioxidant activity with good phenolic and flavonoid contents (400±0.44 mg ascorbic acid equivalent/g dried weight, 263±0.62 mg gallic acid equivalent/g dried weight, 63±0.19 mg quercetin equivalent/g dried weight respectively). Conclusion: The research work revealed the presence of various bioactive phytochemical compounds which show the medicinal importance of leaves Murraya paniculata through a facile extracting method.
