ANTIMICROBIAL AND PHYTOTOXIC ACTIVITIES OF FEW IMPORTANT XERIC PLANTS

Abstract

The present study was conducted to record and report the biological activities of four selected xerophytes species of District Bannu. Phytotoxic effect of Calligonum polygonoides, Sueda fruticosa, Peganum harmala (L.) and Rosa brunonii was conducted by the germination of Cucumus sativus, Brassica olerace, Helianthu annus and Abelmoschus esculentus similarly antibacterial and antifungal activities were also carried out in libratory by using of various strains of bacteria and fungal such as Bacillus subtilis and Escherichia colli, Aspergillus niger and Aspergills flavos. All of the selected plants have inhibitory effect on bacteria growth. In this study the effect of different concentration (.5mg/ml, 10mg/ml) of shade dry leaf methanol extract of Calligonum polygonoides, Sueda fruticos, Peganum harmala (L.) and Rosa brunonii on various strains of bacteria and fungi were investigated. The results showed that the methanol extract of Calligonum polygonoides, Rosa brunonii and Peganum harmala (L.). inhibit the growth of bacteria and fungi just like antibiotic but Sueda fruticosa have little inhibitory effect on Bacterial and fungal strain. Maximum growths of bacteria and fungi were occurred at positive control Petri dish (DMSO); growth were not observe at Petri plate of Tetracycline and Terbinofine test tube.Growth of bacteria and fungi was not observe in higher concentration Rosa brunonii and Calligonum polygonoides on various strains of bacteria and fungi.
