The present study was performed with an aim of determining the phytochemical constituents and antagonistic effect of roots of Curculigo orchioides (family Amaryllidaceae) and Curcuma angustifolia (family Zingiberaceae). Antagonistic effect was evaluated against four UTI causing bacterial isolates by well diffusion method. The results of the study showed, in comparison with Curcuma angustifolia, the root extracts of Curculigo orchioides exhibited higher antagonistic activity against the tested isolates. Also the phytochemical investigation of Curculigo orchioides indicated the presence of phenols, amino acids, glycosides, alkaloids, tannins, terpenoids and coumarins. This study derives in a conclusion that root extracts of Curculigo orchioides can be used to develop antagonistic agents against bacterial isolates causing UTI.
