    Study of antimicrobial activity of the extracts obtained from the alcea setosa leaves and flowers
    (UMT Lahore, 2019) Anwal Raza
    The increased resistance of microorganisms to the currently used antimicrobials has led to the evaluation of other agents that might have antimicrobial activity. Medicinal plants are sources of phytochemicals which are able to initiate different biological activities including antimicrobials. The use of medicinal herbs in traditional system of medicine is a common practice in many cultures around the world especially in Asian societies. Alcea setosa plant is belong to a family Malvacae and is found in different regions of the world. The Alcea setosa plant is used to treat cough, chest pain, intestinal inflammation, respiratory diseases, pectoral diseases, wound healing and female urinary system disorders. It flowers and leaves are also used as a skin laxative, demulcent, diuretic and emollient. The present study was carried out to evaluate the antimicrobial property of Alcea setosa leaves and flowers against certain bacterial strains. The test organism were Bacillus subsitlis, Pseudomonas aeruginosa and Escherichia coli. The antimicrobial activity of Alcea setosa was checked by two different methods, the disc diffusion method and dilution method. All the different extracts (methanolic, ethanolic and aqueous) of leaf and flowers exhibited the significant anti-microbial activity against different strains. Results showed that leaf ethanolic extract showed highest zones of inhibition against Bacillus subtilis, while leaf methanolic shown highest inhibition against E.coli. Similarly, flower ethanolic and flower methanolic and leaf ethanolic showed zones of inhibition only against Pseudomonas aeruginosa in dilution method. The phytochemical test shows that the flavonoids, steroids, terpenoids, tennis, saponins, phlobatanin and alkaloids are present in the plant extracts. These results therefore justify the traditional use of Alcea setosa leaves and flowers to treat different diseases.
