“…Studies of the content of secondary metabolites concerned plant material obtained from natural sites or pot plants, e.g., Saitama Greenery Promotion Center of Kawaguchi City In Japan (Yoshimura et al 2008), the Greek island Zakynthos (Gardeli et al 2008), southern Tuscany (Romani et al 2004), northeastern Tunisia-Nabeul (Aidi Wannes et al 2010), Zaranjan in the district of Fasa (Taheri et al 2013) and others (Mansouri et al 2001;Hayder et al 2004;Tattini et al 2006;Amensour et al 2009;Nassar et al 2010;Agati et al 2011;Kumar et al 2011;Pereira et al 2012;Tumen et al 2012;Goncalves et al 2013;Bouaziz et al 2015;Babou et al 2016;Feuillolay et al 2016). In a study on Myrtus nivelli, Batt & Trap (Touaibia and Chaouch 2015), the authors found that methanol extracts from in vivo sites were richer in polyphenol content (348 μg eq/mg DW total polyphenol content and 152 μg eq/mg DW total flavonoid content) than in vitro culture extracts (respectively 73 and 91). But in those research only one standard was used for polyphenols (gallic acid) and flavonoids (quercetin) total content.…”

“…In recent years, there has been increasing interest in the use of medicinal plants as a source of healthy raw materials (Scarpa et al 2000). According to Touaibia and Chaouch (2015), more than 25% of medicines is directly or indirectly derived from plants. This is related to the preventive action of antioxidants against "civilisation diseases", including cancer (Aidi Wannes et al 2010;Pereira et al 2012;Goncalves et al 2013;Bouaziz et al 2015), and related to the abuse of synthetic drugs, the discovery of adverse side effects and high cost of conventional medicinal products (Aleksic and Knezevic 2014).…”

“…According to the scale of Dalmarco et al (2010), used in this work, 2 bacteria were very sensitive, 3 moderately sensitive and 4 weakly sensitive. With standards used by other authors, plant extracts with MICs values higher than 500 µg/ml (Aligianis et al, 2001) and even much higher than 1000 µg/ml (Maregesi et al, 2008;Abubakar and Majinda, 2016;Touaibia and Chaouch, 2017) were classified as having strong antimicrobial activity. For comparison, LME and SME had excellent activates on all the bacteria tested.…”

This study is aimed at the assessment of antimicrobial potential of Albizia masikororum, a Malagasy Fabaceae. Hexanic and methanolic extracts from fruit pods, stem bark, leaves and seeds were tested by disc diffusion and microdilution methods on 10 pathogenic microorganisms including four Gram positive bacteria, five Gram negative bacteria and one yeast. Only the leaf and seed methanolic extracts, LME and SME respectively, were active on some bacteria. LME and SME had a broad-spectrum activity, with SME more effective. The minimum inhibitory concentration (MIC) values of both extracts were <1000 µg/ml of which 30% <100 µg/ml, 20% between 100 and 500 µg/ml and 50% between 500 and 1000 µg/ml. SME MICs ranked from 6.10 µg/ml (Streptococcus pneumoniae) to 781.25 µg/ml (Yersinia enterocolitica) and those of LME from 97.65 µg/ml (Streptococcus pneumoniae) to 781.25 µg/ml (Bacillus cereus, Streptococcus pneumoniae and Yersinia enterocolitica). LME was bactericidal on all sensitive bacteria whereas SME was bactericidal on some and bacteriostatic on others. Both extracts contained different chemical groups known for their antimicrobial properties, saponins in SME and phenolic compounds in LME.

This work aimed at assessing the antimicrobial activity of Albizia bernieri seed extracts. Methanol extract (SME), alkaloids extracted under basic (Alk1) and acidic (Alk2) conditions, polar saponosides (Sap1) and less polar saponosides (Sap2) obtained by n-butanol fractionation were used. Their activities were tested against 9 pathogenic germs including 4 Gram (+) bacteria, 5 Gram (-) bacteria and 1 yeast using disc diffusion and microdilution methods. Regardless the method used to assess the antimicrobial activity, all extracts were efficient but their effects depended upon the germs tested. They all displayed a broad spectrum activity. Alkaloids were by far the most efficient with an excellent effect (Minimum Inhibitory Concentration or MIC<100µg/ml) against all germs tested. Streptococcus pneumoniae, Streptococcus pyogenes, Clostridium perfringens and Candida albicans were the most sensitive with MICs less than 10 µg/ml. SME and Sap 2 had moderate or low effects (MIC between 100 and 1000 µg/ml) and Sap1 was the less efficient (MIC ≥1000 µg/ml). All the extracts exerted bactericidal or fungicidal action on all sensitive germs. These preliminary results revealed antimicrobial activity of Albizia bernieri seeds that could be used to treat different infectious diseases and might lead to the development of pharmaceutical agents.
