Description
Albizia lebbeck (L.) Benth. Traditionally plant is used as anti-asthmatic, anti-inflammatory, anti-fertility and anti-diarrheal, antiseptic, anti-dysenteric, anti-tubercular, leprosy, paralysis and helminth infection. This study aimed to determine the phytochemical constituents, antioxidant and antibacterial activities. The phytochemical screening was carried out using Petroleum ether, Ethyl acetate and 70% ethanol; preliminary phytochemical screening showed the presence of alkaloids, flavonoids, carbohydrates, tannins, coumarins and saponins in plant extracts. The seeds extract of Albizia lebbeck were tested against gram-positive and gram-negative bacteria by cup diffusion method. The Petroleum ether extract showed high activity against Escherichia coli when compared with other plant extracts. The antioxidant activity was determined by using the free radical scavenging method (DPPH). The result of antioxidant activity reflected low activity as compared with standard (Propyl gallate).
