    (2005) Dogan Y.; Baslar S.; Ay G.; Aydin H.; Yorek N.; Mert H.H.
    From the flora point of view, Turkey is the richest country in Europe and the Middle East, with more than 10 000 vascular plant taxa, and more than 3000 of which are endemics. Therefore, poisonous plant taxa distributing in Turkey is expected to be higher. In this study, the poisonous natural plant taxa distributed in Turkey are identified and given in the table. Results of this study show that 2359 plant species belonging to 97 families are identified as poisonous in Turkey. The families with the highest number of poisonous plant species are identified as Fabaceae (571), Liliaceae (243), Ranunculaceae (140) and Asteraceae (126). Families with the highest number of poisonous genera are Fabaceae (15), Asteraceae (14), Liliaceae (14) and Ranunculaceae (11). Among the determined genera, all the members of 90 genera are poisonous. Among these genera, the top three numbers of poisonous species are Astragalus (347), Verbascum (220) and Allium (141).

    Evaluation of antimicrobial activity of some endemic Scrophulariaceae members from Turkey
    (2005) Dulger B.; Ugurlu E.
    The methanol extracts obtained from endemic Scrophulariaceae members Verbascum protractum Fenel ex Tchihat., Verbascum bellum Hub.-Mor., Verbascum dalamanicum Hub.-Mor., Scrophularia mersinensis Lall, Scrophularia cryptophila Boiss. & Heldr., Pedicularis olympica Boiss., and Veronica lycica E. Lehm. have been investigated for their antimicrobial activity. Antimicrobial activity was determined with Escherichia coli ATCC 11230, Staphylococcus aureus ATCC 6538P, Klebsiella pneumoniae UC57, Pseudomonas aeruginosa ATCC 27853, Proteus vulgaris ATCC 8427, Bacillus cereus ATCC 7064, Mycobacterium smegmatis CCM 2067, Listeria monocytogenes ATCC 15313, Micrococcus luteus CCM 169, Candida albicans ATCC 10231, Rhodotorula rubra DSM 70403, and Kluyveromyces fragilis ATCC 8608 by the disk diffusion method. The extracts of all Scrophulariaceae members used in this study had strong antimicrobial activity against the Gram-positive bacteria and yeast cultures. © 2005 Taylor & Francis Ltd.
