The Juniperus excelsa is considered an important medicinal plant by the local population of Balochistan, Pakistan. The species is facing a grave threat by a parasitic and epiphytic angiosperm, dwarf mistletoe, Arceuthobium oxycedri (DC.) M. Bieb. (Viscaceae). The methanolic extract of A. oxycedri was studied for its chemical composition and biologically active compounds for the first time. The extract was assayed for antibacterial, antifungal, phytotoxic, cytotoxic and insecticidal activities. The antibacterial and antifungal activities of the extract were determined against ten bacterial and ten fungal strains by agar well diffusion and disc diffusion assay. The extract was highly effective against three bacteria Pseudomonas aeruginosa, Escherichia coli, Bacillus subtilis and a fungus Candida albicans . The phytotoxic effects showed that it was extremely toxic for Lemna acquinoctialis . It showed high cytoxicity for brine shrimps at all concentrations and was found to be significantly cytotoxic against Candida albicans when checked by flow cytometer. However, the extract was not effective against the pests tested.

Extracts of five Euphorbia species were studied for their activity against Bacillus subtilis, Staphylococcus aureus, Escherichia coli and Candida albicans. E. amygdaloides and E. helioscopia proved to be the most effective against them. Some plant metabolits were also examinated against the microorganisms: podophyllin and rhamnetin caused the greatest, b-sitosterine the smallest inhibition among them. Bacillus subtilis was the least sensitive among the studied microorganism in this study.

Pairwise interactions between four antifungal compounds were studied. The β-1,3-glucan synthase inhibitor echinocandin B (ECB) showed synergistic effect with the cell wall hydrolase ChiB chitinase and EngA β-1,3-glucanase on Saccharomyces cerevisiae, Candida albicans, Aspergillus rugulosus and A. fumigatus. The antifungal protein of Penicillium chrysogenum (PAF) did not influence the antifungal activity of ChiB or EngA, but showed antagonistic effect with ECB on A. nidulans, A. rugulosus and A. fumigatus. PAF had no significant effect on the growth of the tested yeasts as it was expected and did not influence significantly the antifungal activity of ECB, ChiB or EngA against yeasts.

In this study, the pollen analyses and antimicrobial effect were conducted in honey samples, which were collected from seven localities where apiculture has intensively been practiced. Upon pollen analyses of 16 different plants have been determined. The plants contributing nectar to honey samples in Elazig were found as follows; Fabaceae: Astragalus, Trifolium, Vicia, Onobrychis; Asteraceae: Centaurea triumfettii, Carduus, Xeranthemum, Helianthus annuus; Lamiaceae: Salvia, Mentha;Rosaceae: Rubus, Prunus;Vitaceae: Vitaceae: Vitis;Apiaceae: Daucus; Zygophyllaceae: Peganum harmala; Ranunculaceae: Ranunculus. The honey sapmles have inhibited the growth of bacteria used in our work at varying degrees. None of the samples had any antifungal effect against Candida albicans FMC-17 and Saccharomycescerevisiae UAG-102
