The present study aimed to extract the active content of saponins, glyclosides, alkaloids and tannins from the Cuscuta lehmanniana (Growing on Populus Sp) And test their biological activity against some negative and positive bacterial species (Staphylococcus epidermidis Staphylococcus aureus gram positive and Escherichia coli, shigella, Klebsiella pneumonia, Salmonella Paratyphi gram negative) And pathogenic fungus is Trichophyton rubrum, The results showed the activities of the studied extracts against the tested bacterial species, that this activity was higher in tannin extract compared to the tested extracts with an Averaged inhibition zoon (AIZ) 13.97 mm , It was also found that the concentration of 100 mg / ml is the most effective in inhibition of bacteria on that the most inhibitory activity recorded by tannin extract with an (AIZ 23.33 mm) against S.epidermidis. The results also showed that the treatment of positive control (Nystatin) for the fungus is more effective in inhibiting T. rubrum with a growth diameter of 12 mm , and that the concentration of 5 mg / ml of saponins and alkaloids extract is most effective in inhibiting the fungus with an average growth of 33.33 mm and 30 mm, respectively
