Examination of Phytochemicals, Antioxidant and Antibacterial Activity of Hemigraphisalternate

Abstract

Plants as the source of medicine plays avital role in the health service around world. Hemigraphis alternata (Acanthaceae), exotic plants adapt to India, is versatile tropical lower-creeping perennial herbs that reachheight of 15 - 30 centimeters. The matured leaf of Hemigraphis alternata was collected from Kurunthankode , Kanyakumari district. Phytochemical screening of the H.alternata revealed the presence of some phytoconstituents such as carbohydrate, protein, alkaloid, flavonoid, saponin, terpenoid and tannin. Previous report shows that H.coloratacontains similar compounds like saponins, flavonoids and terpenoids. The antioxidant property of H.alternata extract were compared with standard ascorbic acid. The ethanolic extract of H.alternata leaf exhibit good scavenging activity with dose dependent manner. Antimicrobial activities of H.alternata leaf extract show the ethanol extract has the maximum activity against bacteria and fungi. This study revealed the presence of different Phytochemical, antioxidant and antibacterial activities of plant H.alternataand can be suggested that the bioactive components are promising natural antimicrobial agents.
