Aqueous extracts of Corrigiola telephiifolia and Anacyclus pyrethrum were studied in vitro for their antimicrobial properties. These plants were collected from the Central Middle Atlas region. Corrigiola telephiifolia Pourr. and Anacyclus pyrethrum (L.) Link are widely used as a natural drug for the treatment of various infectious diseases. Phytochemical screening of the plants showed the presence of flavonoids, saponins, tannins, steroids and alkaloids. The determination of the polyphenols in the aqueous extract of the two plants revealed the presence of significant amounts of polyphenols (58.5 ± 0.76 mg equivalent of gallic acid (GEA) per gram of extract for C. telephiifolia, and 97.57 mg equivalent of gallic acid (GEA) per gram of extract of A. pyrethrum). The antimicrobial activity of the aqueous extracts against three bacterial strains was evaluated on the basis of the inhibition zone using the disk diffusion assay. The aqueous extract of Corrigiola telephiifolia is slightly active on E. coli. At a concentration of extract 100 μg mL-1, the size of the inhibition zone equal to 9 ± 0.06 mm. Whereas S. aureus, E. coli and K. pneumoniae showed a sensitivity to the macerate of Anacyclus pyrethrum at the concentration 100 μg mL-1 of extract with an inhibition zone 16.55 ± 0.6 mm, 14.95 ± 1.25 mm and 10.83 ± 0.96 respectively.

Fungi are the cause of many human, animal and plant diseases. In the context of valorization of aromatic and medicinal plants of the Central Middle Atlas of Morocco, three plants were selected, based on the results of an ethnobotanical survey in this region, to evaluate their antifungal activity against five Fungi, namely Fusarium oxysporum sp. albedinis, Alternaria sp, Penicillium expansum, Aspergillus brasiliensis and Rhizopus stolonifer. A quantification of the total polyphenols was mesured out for the aqueous extracts of the studied plants Urginea maritima (L.) Baker of the Liliaceae family, Chenopodium ambrosoides L. of the Chenopodiaceae Family and Calendula officinalis L of the Asteraceae family, to choose the form in which the tests will be performed. According to the results, Aspergillus brasiliensis was found sensitive to the macerate of Urginea maritima (L.) Baker at a concentration of 10.71 mg / ml. The percent of inhibition (PI) of mycelial growth was 43.33%. At the same concentration, Fusarium oxysporum showed a slight sensitivity with PI = 19.25%. Furthermore the Chenopodium ambrosoides L decoctate was active against Aspergillus brasiliensis, Alternaria sp and Fusarium oxysporum with PI respectively equal to 41.11%,European Scientific Journal August 2017 edition Vol.13, No.24 ISSN: 1857 -7881 (Print) e -ISSN 1857-7431 48440.37% and 27.77%. However, the infusion of Calendula officinalis L showed no effect on the strains tested.Keywords: Antifungal activity, aqueous extracts, aromatic and medicinal plants, Central Middle Atlas, Morocco.

“…As described before in several studies, the phenolic components (flavonoids, flavonoids, phenolic acid, tannins, etc.) revealed a wide range of biological properties such as antibacterial, antiviral, anticancer, anti-proliferative and anti-inflammatory [41][42][43][44][45]. These compounds or secondary metabolites particularly possess also anti-protozoan activities, especially against Plasmodium, Leishmania and Trypanosoma spp.…”

Aim The objective of the present study was to investigate in vitro anticoccidial effect of olive pulp (Olea europaea L var. Chemlal) extract on the destruction of Eimeria spp. oocysts isolated from infected chickens naturally. Materials and methods The olive pulp (OP) powder was stirred manually in aqueous ethanol in preparation for extraction using the microwave-assisted extraction system. The identification of the phenolic compounds was obtained by ultra-highperformance liquid chromatography-mass spectrometry with electrospray ionisation (HPLC-ESI-MS). The treatment of Eimeria oocyst with OP extract and standard compounds (quercetin and oleuropein) leads to their lysis as shown by the release of substances absorbing at 273 nm. Results Our results showed that the maximum number of reduced oocysts was recorded after 8 h of incubation of optimum OP extract, quercetin and oleuropein for different periods of time. Also, the number of Eimeria oocysts decreased considerably with increase concentrations after adding the optimum of OP extract in concentration ranging from 0.023 to 0.371 mg/ ml. Positive correlation between the optimum OP extract concentrations and the number of Eimeria oocysts reduced was R 2 = 0.959. From this in vitro experiment, it can be concluded that the OP extract possesses an anti-Eimeria spp activity. Conclusion To our knowledge, this is the first time that quercetin and oleuropein were tested to evaluate their anticoccidial activity. The findings of this study showed that phenolic compound of OP extract tested separately possesses anti-Eimeria spp. effect. Further studies should be carried out to test its in vivo efficacy of the OP bioactive compounds in broiler chickens.
