They were collected from Dagon University, East Dagon Township, Yangon Region during the flowering and fruiting periods. The morphological characters, preliminary phytochemical test, physicochemical investigation and antimicrobial activities were studied. In morphological study, the plant was evergreen herb, stem less and rhizome horizontal. Preliminary phytochemical test showed the presence of alkaloid, α-amino acid, glycoside, carbohydrates, reducing sugar, phenolic compound, flavonoid, steroids and trace of terpenoids. In physicochemical investigation, the water soluble ash content of leaves was the most highest than the other solvents. In antimicrobial activities, the ethanol extract of leaves showed the most significant inhibition on Vibrio cholerae.
