Abstract: The current search targeted the type Merremia dissecta (JACQ) from the family Convolvulacea. It is one of the plants that have not been studied in Iraq previously and saw a rapid spread after 2003 which were seen developing in the fields and spaces of the Faculty of Agriculture at the University of Baghdad in,), so the study aimed to documentation the plant locally and conducted chemical analysis of Merremia leaves showed presence of fat, protein, carbohydrate, ash, fiber and dry matter with percentage 0.57, 24.25, 22.74, 5.69, 10.28and, 94.31%respectively. By qualitative detection were indicated the presence of tannins, alkaloids and with greater extend glycosides and flavonoids. The percentage of phenols 52.98 and 87.7, while for flavonoids were 2.65 and 7.5 mg / 100mg for aqueous and Ethanolic extract respectively. The aqueous extract has an inhibition activity against negative bacteria P. aeruginosa and gram-positive Staphylococcus aureus with a rate of inhibition diameter 10 and 7 mm respectively. It also has an inhibition effect toward Aspergillus oryzae with inhibition percentage 26.56, 29.68 and 39.06 % at concentration 1000, 2000, 300 ppm respectively and with inhibition percentage reached 27.5, 30.0 and 45.0 % toward Penicillium. spp at the same concentrations also noted increasing of inhibition percentage with increased concentration against two types of mold. Identification some active groups by FTIR technology and existence of: O-H, C-C, C=C, C-O, C=O, C-H and N-H with different stretching frequencies. The Ethanolic extract showed only a stretching frequency between 3000-3250 cm-1 indicating group N-H.
