The Chemical Composition And Antimicrobial Activlty Of Impatiens Tinctffii A Rich

The plant Impatiens tinctoria A-Rich grows widelyrnin Ethiopia. its tubers are traditionall;y used to dyernthe palms of nails of women and to treat infections ofrnthe hands and feet.rnThe methanol extract of I. tinctoria gave dark redrnsolution which was chromatographically separated to giverntrace cnnount of a comp01md which readily dissolves inrnbenzene ethanol and carbon tetrCchloride but vms insolublernin Ivater. Thts compound was characterized by comparingrnwith stalndard naphthoquinones and the TLC, UV, MS,rnLC corresponds with 2-methoxy-l, 4•-naphthoquinono.rnis presence of anthocyaniclin and tri terpene ~'IRSrnalso observed. .,(evie", of the liberature r8v0a1s that 2-rnlilethoxy-•l, 4,-naphthoquinone is present in flowers ofrnI.Balsamina .• Hence, this study adds one more species ofrnthe genus Impatiens to plants that are knolm to contanrn2-methoxy-1, 4--naphthoquinone and anthocyanidin.rnThe methanol extract of I. tinctoria was found tornhave an antifungal and antibiotic activity • this extractrninhibited the growth of staph qureus E.coli and candida albjcans at concentration levels of 1:448,1:280 respectively
