“…The antioxidant activity of the extracts was determined by the DPPH assay [38][39][40][41]. A series of extract solutions were made in 70% ethanol in the range of concentrations from 0.01 to 1.0 mg/ml, and DPPH radicals in the concentration of 0.3 mM in 70% ethanol for the purpose of the determination of antioxidant activity.…”

In this study, we have examined the yield of extracted substances obtained by means of extraction using 70 % ethanol (v/v), the content of total phenols and flavonoids, as well as the antioxidant activity of the extracts obtained from the samples of the herbs dried by means of different techniques. Wild mint Mentha longifolia (L.) Hudson was dried naturally in a laboratory oven at a temperature of 45 °C and in an absorptive low temperature condensation oven at 35°C. The highest yield of extracts was obtained from the naturally dried herbs and the lowest from the herbs dried in the low temperature condensation drying oven. The content of total phenols and flavonoids was determined by spectrophotometric methods with an FC reagent and by the complexation reaction with aluminium-chloride, respectively. The extract of the naturally dried herbs had the highest overall content of phenols (113.8±2.0 mg of gallic acid/g of the dry extract) and flavonoids (106.7±0.3 mg of rutin/g of the dry extract). The highest antioxidant activity determined by the FRAP and DPPH assay was determined in the extracts obtained from naturally dried herbs (2.76±0.15 mmol Fe2+/mg of the dry extract and EC50=0.022±0.001 mg/ml), while the lowest was obtained from the extracts of herbs dried in the laboratory oven (1.13±0.11 mmol Fe2+/mg of the dry extract and EC50=0.033±0.001 mg/ml). The HPLC-DAD analysis result show that the greatest content of phenolic compounds show extract obtained from naturally dried plant material. The dominant phenolic component in the all extracts is Kaempferol 3-O-glucoside. The content of all phenolic compound strongly depend on the drying conditions

“…Some of these plants have been previously studied, with different solvents, parts and sometimes using different strains and different methodological approachs. [23][24][25][26][27][28][29][30][31][32][33][34][35][36] Although, there are some reports concerning antimicrobial activities of some of the plants tested (Table 9), the main difficulties in comparing previous studies, lies in the fact that the criteria, method and end-points used for reporting the activity are very diverse. As can be seen in the table in the case of Gossypium barbadense, the minimum concentration used in the study by Ikobi et al 32 and regarded to represent antibacterial activity, is considered in our study to be too high (10 folds increase compared to the maximum dose we utilized), and regarded as not having activity.…”

infections and resistance to antifungal agents have increased significantly in immunocompromised patients and these infections are responsible for a high rate of morbidity/mortality in severe cases. 1,4 The growing need for more effective and safe antimicrobial agents has led to the renewal of multidisciplinary investigation on natural products, where new approaches combined with traditional techniques, are accelerating tracking of substances, which present antimicrobial activities. In addition, it has also allowed identification of the molecular targets responsible for their effects, moreover, many of these substances present new mechanisms of action. 4 Medicinal plants constitute an arsenal of chemicals

“…In another study 9 , antimicrobial effectiveness of the ethanol extract (70%) of P. major L. leaves against E. coli, P. aeruginosa, B. subtilis, S. aureus, C. albicans, S. cerevisiae and Aspergillus niger was investigated with agar welldiffusion method; and they stated that P. major L. has antimicrobial effectiveness against the bacteria and mycotic agents used in the study; and that the most sensitive agent against the extraction was S. cerevisiae. Fabíola Barbieri Holetz et al 12 investigated the effectiveness of P. major L. ethanol-water (90-10%) extraction against S. aureus, Spilanthes acmella, Lippia alba, and Achillea millefolium; and found that the extract showed a weak antimicrobial activity on the bacteria species studied.…”

SummaryIn this study, minimum inhibitor concentrations of acetone and ethyl alcohol extracts of Plantago major L. leaves on predetermined bacteria species was determinbed by Macrodilution liquid (tube) method. Both extracts were tested for nine bacteria species (Bacillus cereus, Bacillus subtilis, Staphylococcus aureus, Staphylococcus epidermidis, Escherichia coli, Klebsiella pneumonia, Pseudomonas aeruginosa, Proteus mirabilis, Salmonella enteritidis). Ethyl alcohol extract showed no antibacterial activity against all species (except for E. coli and B. cereus), but acetone extract was effective on selected bacteria species in different concentrations.
