(Hrsg.) Reviews of Progress, (Mai 2014)

Zusammenfassung

Ethanolic, Methanolic, Cold water and Hot Water extracts of twenty two medicinal plants in Hazara Division were tested for antibacterial activity against six human pathogenic bacterial strains using well diffusion method. Total of twenty two medicinal plants were studied in the present investigation. In which seventeen medicinal plants were show moderate to good antibacterial activity against tested bacterial strains. Which were included Camellia sinensis, Solanum jacquinii (Solanaceae), Datura alba (Solanaceae), Withania somnifera, Swertia chirata (Gentianaceae), Solanum xanthocarpum (Solanaceae), Ricinus communis (Euphorbiaceae), Cannabis sativa (Cannabaceae), Ephedra vulgaris (Ephedraceae), Brassica nigra (Brassicaceae), Centella asiatica (Umbelliferae), Solanum nigrum (Solanaceae), Primula vulgaris (primulaceae), Cedrus deodara, Zanthoxylum armatum (Rutaceae), Mentha piperita (Lamiaceae). Other five medicinal plant which included Colycynthis vulgaris (Cucurbitaceae), Ziziphus jujuba (Rhamnacae), Carica papaya (Caricaceae), Ricinus communis. (Euphorbiaceae) and Solanum xanthocarpum show no antibacterial effects. Hot water extracts of all medicinal plants show no activity against any test organisms. Medicinal plants are growing abundantly in Hazara division and other part of Pakistan. There is also need for further investigation to explore the flora of Hazara Division and screening for new antimicrobial agents and fortitude of their Phytochemical studies to establish the types of compounds responsible for the activity and to recognize which can be used in drug development for safe health care services.
