SCREENING OF POTENTIAL MEDICINAL PLANTS FROM DISTRICT SAWAT SPECIFIC FOR CONTROLLING WOMEN DISEASES

SARWAT, ZABTA KHAN SHINWARI^* AND NISAR AHMAD

Abstract: Ethnobotany provides a scientific rationale to identify medicinally important plant species, especially for finding new drugs that play vital role in the treatment of different diseases. This ethnobotanical survey of Swat, Khyber Pakhtunkhwa (KP) was carried out to identify medicinally important plant species that are traditionally used to treat gynecological disorders and infectious diseases, and to study their antimicrobial potential against pathogens that cause infections in females. The antimicrobial activities were investigated using the well diffusion method against four different bacterial strains and one fungal strain. Results showed that out of 12 plants studied, seven plants exhibited inhibitory effects against Candida albicans, Staphylococcus aureus, Klebsiella pneumoniae and Escherichia coli. Woodfordia fruticosa, Quercus dilatata, Erythrina variegata, Ficus religiosa and Berberis lycium showed high antifungal activity against C. albicans with  minimum inhibitory concentration (MIC) values of 2.5, 1.25, 0.625, 1.25, 0.3125 mg/ml and minimum bactericidal concentration (MBC) values of 5, 2.5, 1.25, 2.5, 0.625 mg/ml, respectively. Both Woodfordia fruticosa and Quercus dilatata showed antimicrobial potential against E. coli and K. pneumoniae with similar MIC values of 2.5 mg/ml and MBC values of 5 mg/ml. Plants exhibiting inhibitory potential against S. aureus were Woodfordia fruticosa, Quercus dilatata, Azadirachta indica and Curcuma longa and all of them possessed similar MIC values of 5 mg/ml and MBC values of 2.5 mg/ml, respectively. None of the plants showed antimicrobial activity against Pseudomonas aeruginosa. Proximate analysis showed that in comparative assessment of the various species, Zanthoxylum alatum had the highest fat and energy values.
