Phytochemical and Antimicrobial investigation of Taleghan plants species

Taleghan a highly beautiful area located in 80 km.Nw of Tehran, has a suitable ecology for growth of diverse plants. There are many species that are used in folk medicine by inhabitants for treatment of infection disease. In this study 158 species were collected, identified and deposited in the herbarium of faculty of pharmacy, Tehran University of medical sciences. Prephytochemical, antibacterial and anti fungal effects of plant extracts considered and for this proposes hydroalchoholic extracts were prepared using suxhelt apparatus, then dried over vacuum system.

Qualitative tests for assessment of four components: alkaloids, flavonoides, saponins, and tannins were done via laboratory tests. Each extract was used due to find antifungal and antimicrobial properties against:Candida, Aspergillus, Nocardia, Microspom, Trychophyton, Streptococcus, Proteus, Escherchia, Salmonella, Staphylococcus and Pseudomonas. Blood agar and muller hinton were used as cultures media.

Results of pre-phytochemical tests were as fallows: 84% had saponin, 42% tannin, 45% flavonoids, 13% alkaloids.69 species had attractive antimicrobial effect and three species including Epilobium hirsutum L., Centaurea brugeriana and Centaurea virgata were the best. Antifungal and antibacterial tests showed that the effective species were Achillea micrantha Wild., Matricaria disciformis C.A. Meyers, Mentha longifoliaL., Hypericum hyssopifolium Chaix. and Ducrosia anethifolia(DC) Boiss. in conclusion the species of containing saponin were more effective.
