“…These results are in agreement with our previous study which has reported the antibacterial effect of hydro-methanolic extracts of leaves and seeds of C. australis 14 , as far as various extracts from this plant against S. aureus, P. aeruginosa, E. coli and B. subtilis 16 , S. aureus and P. aeruginosa 8 , P. syringe 17 and S. aureus, L. monocytogenes, P. aeruginosa and E. coli 18 . Antifungal potential: As shown in Table 5, a significant and dose-dependent antifungal effect was obtained with all extracts tested.…”

The dichloromethane, ethyl acetate, butanol and methanol extracts from leaves of Celtis australis, used to treat different disorders in Moroccan traditional medicine, were screened for their contents of total polyphenols, flavonoïds and condensed tannins and antimicrobial activity against seven bacterial strains (Staphylococcus aureus, Bacillus cereus, Bacillus sp, Listeria ivanovii, Escherichia coli, Citrobacter freundii and Salmonella sp) and three fungi (Candida albicans, Candida tropicalis and Aspergillus niger), using Ampicillin and Fluconazole as references. The antimicrobial activities of plant extracts were assessed by the disc diffusion and minimum inhibitory concentration (MIC) methods. All values are expressed as mean ± SD. The obtained results showed that the butanol extract exhibited significant and dose-dependent antibacterial activity against S. aureus, B. cereus, Bacillus sp and Salmonella sp. The other extracts exerted moderate antibacterial activity, except methanol extract that inhibited significantly Listeria ivanovii. In the same conditions, the butanol, dichloromethane and ethyl acetate extracts showed significant and dose-dependent antifungal activity against all tested fungi, although at different extents, while methanol extract exhibits moderate effect. The plant extracts yielded important polyphenolic contents assessed by total polyphenols, flavonoïds and condensed tannins. A positive linear correlation was established between these compounds and the antimicrobial activity of plant extracts. These results are corroborating the traditional medicine use of Celtis australis which could be a good candidate for further studies.

“…This was confirmed also in the present study with leaves collected in October; in addition, comparable activities were also found for the fruit mesocarp (Table 4). Badoni et al (2010) also studied the antimicrobial activities of crude extracts from hackberry fruit and reported antibacterial activities against S. aureus, B. subtilis, P. aeruginosa, and E. coli. Although different extraction solvents were used and lower MICs were determined, the growth of S. aureus was again inhibited at lower concentrations than for P. aeruginosa.…”

Celtis australis is a deciduous tree commonly known as Mediterranean hackberry or the European nettle tree. The fruit of hackberry are seldom used for nutritional purposes. The nutritional and physicochemical properties of ripe hackberry fruit from Istria (Marasi village near Vrsar, Croatia) were determined, including water, total fiber, protein, vitamin, mineral, and phenolic contents. This analysis demonstrates that the hackberry fruit is a valuable source of dietary fiber, protein, and vitamins, and of pigments such as lutein, β‐carotene, zeaxanthin, and tocopherols. The seasonal differences associated with the different growth stages for the element composition, total phenolic content, and phenolic profile were also determined for hackberry mesocarp and leaves. Water and ethanol extracts were prepared from mesocarp and leaves harvested at different growth stages and their phenolic profiles and antioxidant and antimicrobial activities were investigated. This study demonstrates that water and ethanol extracts of hackberry fruit and leaves collected at different growth stages contain epicatechin, gallic acid, vanillic acid, 3,4‐dihydroxybenzaldehyde, delphinidin‐3,5‐di‐O‐glucoside, cyanidin‐3,5‐di‐O‐glucoside, and pelargonidin‐3,5‐di‐O‐glucoside. They also show some antimicrobial and antifungal activities. Further studies are needed to identify and define the active ingredients of these hackberry leaf ethanol extracts.

Evaluation of the antimicrobial activity of a blend of monoglycerides against Escherichia coli and Enterococci with multiple drug resistance

et al. 2017

Bacterial antibiotic resistance is a natural phenomenon, seriously affecting the treatment of infections. The biggest danger is that current antibiotics are not able to eradicate the resistant strains. In recent years, alternative antibacterial substances are being sought, which can help in these cases. Fatty acids and monoglycerides are known among the natural substances for their antimicrobial properties and, important detail, bacteria do not develop resistance to them. In this work, we studied the antimicrobial effects of a monoglyceride blend against some multi-resistant Enterococci and Escherichia coli strains. Based on literature data, a blend of fatty acids and their monoglycerides was created and its antimicrobial activity was evaluated against 37 strains of E. coli and 17 Enterococci presenting resistance to at least two antibiotics. A different behavior was observed in the two groups of bacteria, proving that alternative substances can be considerate for the potential treatment of multidrug-resistant strains.
