In vitro activity of Triazolo[1,5-a] pyrimidine carboxylic acid extracted from microalgae Hapalosiphon welweschii againstTrichomonas vaginalis

Abstract

The present study targets the protozoan parasite Trichomonas vaginalis that causes a healthy problems among
women and rarely among men , by the application of natural product or secondary metabolites extracted from the
microalgae Hapalosiphon welweschii for the first time in Iraq . methanol extract was explained high activity in three
concentration recording 100% of parasite death at 200 µg\ml of methanol extract in about two days while 150 and
100 µg\ml of extract reports activity against the parasite after three and four days post treatment respectively . GC-
Mass spectrum of the methanol extract has explain presence of the compound Triazolo[1,5-a] pyrimidine carboxylic
acid in about 13.28 % from the total composition of methanol extract of microalgae H. welweschii .
