“…According to Mezouar et al methanolic extracts of root barks of B. vulgaris have presented a very weak antibacterial activity against all tested strains including S. aureus. 25 Comparing results found in this study with those of the literature, we notice in a previous work on antimicrobial activity of some medicinal plants from Tunisia, that methanolic extracts of C. monspeliensis leaves have shown an interesting activity against P. aeruginosa, S. aureus, E. faecalis with inhibition zones diameters of 18.0, 20.0 and 15.0 mm, respectively. 26 Whereas, water-methanol extracts of fruit peels of pomegranate (P. granatum) have demonstrated a moderate activity when they were tested on S. aureus, P. aeruginosa and K. pneumoniae (13.0, 18.0 and 16.0 mm, respectively).…”

“…31 The results of MICs showed that MIC values of B. vulgaris root barks extracts found in this study were lower than those found in a previous work, which were on the order of 2.5 and 5 mg/mL against E. faecalis and S aureus and 20 mg/mL against E. coli and E. cloacae, respectively. 25 This activity is due to berberine, an alkaloid from Berberis species, responsible of antimicrobial activity against Gram positive and Gram negative bacteria. 32 Comparatively, the ethanolic extracts of Cinnamomum zeylanicum barks gave MBC values ranging from 2.5 to more than 10 mg/mL, against a variety of Gram-positive and Gram-negative bacterial strains.…”

Introduction: The objective of this study was to evaluate the antibacterial activity of hydromethanolic extracts of Berberis vulgaris, Cassia angustifolia, Cinnamomum cassia, Cistus monspeliensis, Nigella sativa, Punica granatum, Rhus tripartata, Withania frutescens and Zingiber officinale against different Gram-positive and Gram-negative reference bacterial strains. Methods: The evaluation of antibacterial activity for different extracts of each plant was carried out using the disc diffusion method and determination of minimum inhibitory concentration (MIC). Results: The plant extracts showed zone of inhibition ranging from 06.0 to 23.0 mm against one or more tested bacteria, and their efficacy in terms of MICs where ranged from 0.1 to 12.8 mg/mL. The Refluxed and Macerated extracts of these plants have shown relatively similar results in terms of diameters of inhibition and MICs. The extracts of B. vulgaris, C. monspeliensis and P. granatum demonstrated relatively high activity as compared to the other plant extracts mainly against S. aureus, E. faecalis and E. cloacae. Conclusion: Findings of this study indicate that hydromethanolic extracts of these plants have antibacterial activity against the different tested bacterial strains. This activity supports their use in treatment of infections caused by such resistant bacteria.

“…For example, the flavonoids have been reported to be effective against a wide range of microorganisms as they easily disrupt microbial membranes (Tsuchiya et al, 2003). The activity of the extract against the test organisms was relatively weak which corroborates the earlier work by Mezouar et al, (2014) where a very poor antibacterial activity was demonstrated by the extract of B. vulgaris against all species of organisms tested.…”

This study was carried out as a result of the belief that certain medicinal plants have antimicrobial activity against pathogenic bacteria and fungi species, hence the in vitro antimicrobial activity of the extract and fractions of Euphorbia graminea was performed against bacteria (Staphyloccocus aureus, Escherichia coli, Pseudomonas aeruginosa) and fungal (Candida albican) non-clinical isolates. The methanol extract of Euphorbia graminea was fractionated via solvent-solvent partitioning and vacuum liquid chromatographic techniques and the corresponding fractions were tested for phytochemicals and were biologically tested against the organisms employing the agar well diffusion method. While the extract and partitioned fractions were tested at concentrations between 4.69-300 mg/mL, the vlc subfractions were tested at 12.50-200 mg/mL against the organisms. The MIC of the active vlc subfractions was also tested (9.38-37.5 mg/mL). The alkaloids as well as glycosides, tannins, terpenes and steroids were detected among the extracts and fractions of E. graminea. The extract showed mild activities against the test organisms with the highest zone of inhibition of 7.00 mm recorded at 300 mg/mL against S.aureus. The activities of both extract at 300 mg/mL, showed notable increase against the organisms used, with zones of inhibition of the aqueous extract been 10.50 and 9.50mm and for the chloroform extract, 16.50 and 13.05mm (S. aureus and E. coli respectively). The vlc sub-fraction 6-8 (C) among the other subfractions was more potent against S. aureus, E. coli and C. albican as 16.50, 12.00 and 0.50 mm zones of inhibition were recorded at 100 mg/mL. The zones of inhibition against these organisms later increased to 20.00, 18.50 and 15.00 mm at 200 mg/mL. This study has highlighted the fact that the plant E. graminea has antimicrobial activity which occurs more in the partitioned chloroform and its chromatographic vacuum liquid subfraction (6-8) that gave the highest activity. However, in order to isolate the active biological components and to determine their safety in drug production, further studies are needed.

“…Ces molécules pourraient justifier l'utilisation de cette plante dans la pharmacopée traditionnelle. En effet, selon plusieurs auteurs, ces métabolites secondaires possèdent des activités antifongiques, antibactériennes et antiparasitaires (Frankel, 1993 ;Haluk et al, 2001 ;Olajidé et al, 2003 ;Zirihi et al, 2005 ;Okigbo et Ajalie, 2005 ;N'Guessan et al, 2009 ;Mezouar et al, 2014).…”

The high cost of fungicides, the international markets standards for agricultural product quality, the environmental issues and consumer health discourage to the application of chemical control. The strategy is therefore to develop alternative solutions, less expensive and addresses environmental concerns. This study was conducted to evaluate the fungicidal potency of Crotalaria retusa L. on Phytophthora sp. and Fusarium solani, two phytopathogenic fungi. This plant was selected after an ethnobotanical study conducted in the sub-prefecture of Lauzoua in Côte d'Ivoire. It is considered to be the most widely used in the treatment of microbial diseases. The phytochemical screening of this legume species was carried out, and showed the presence of saponosides, sterols, tannins, alkaloids, flavonoids, polyphenols, quinones and polyterpenes. The sensitivity of these two phytopathogenic fungi strains was tested in vitro in presence of the aqueous extract of Crotalaria retusa L. by using double dilution method on PDA medium (Potato Dextrose Agar). The minimum inhibitory concentration (MIC) of spawn growth was 1.56 mg/ml for both fungi. The minimum fungicide concentration (CMF) was 6.25 mg/ml for Phytophthora sp and 12.50 mg/ml for Fusarium solani. The presence of chemical compounds in this plant justifies its antifungal activity and its traditional use areas.
