|Abstract:||The plant Impatiens tinctoria A.Rich grows widely in Ethiopia. Its tubers are traditionally used to dye the) palms and nails of women and to treat infections of the hands and feet. The methanol extract of I.tinctoria gave clerk red solution which was chromatographically separated to give trace amount of a compound which readily dissolves in benzene, ethanol and carbon tetrachloride but was inso-luble in water. This compound was characterized by cm-, paring with standard naphthoquinones and the TLC, DV, LS, LC corresponds with 2-methoxy-1, 4-naphthoquinone. The pressence of anthocyanidin and triterpene was also observed. JeView of the liberature reveals that 2- methoxy-1, 4-naphthoquinone is present in flowers of I.Balsamina. Hence, this study adds one more species of the genus .1iTatiens to plants that are known to contain 2-methoxy-1, 4-naphthoquinone and anthocyanidin. The methanol extract of i.tinctoria was found to have an antifungal and antibiotic activity. This extract inhibited the growth of Staph.Qureus , B.Coli and Candida albicans at concentration levels of 1:658, 1:448, 1:280 respectively,|
