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

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 μgml of methanol extract in about two days while 150 and 100 μgml 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 .
