“…Plant extracts and essential oils can control microbial growth which depends on the chemical composition which is dependent on the method of extraction and solvent type. Şapci and Vural (2018) indicated that the antimicrobial and antifungal activity of Echinops emiliae extract could be change with the type of used extracts [5]. Besides, they are used in other industries including traditional medicine, dietary supplements, recombinant protein manufacturing and functional foods [14].…”

This study was conducted to evaluate the chemical composition and antibacterial activity of methanolic extract from Echinops robustus on typical food-borne pathogens. Chemical composition of the extract analyzed by gas chromatography-mass spectrometry (GC-MS). The GC-MS analysis of the extract revealed 54 compounds in which Butanal (2.222%), 4-Heptanone (1.717%) and Palmitic acid (4.799%) were the major constituents. The agar disk diffusion method was used to study the antibacterial activity of Echinops robustus methanolic extract against 5 bacterial strains. The extract of Echinops robustus showed moderate antibacterial activity against two gram-positive and three gram negative microorganisms tested with higher sensitivity for gram positive ones (Clear zone= 10mm for Bacillus cereus and 12mm for Staphylococcus aureus). Minimum inhibitory concentrations (MIC) and minimum bactericidal concentrations (MBC) were quantified by micro-dilution method. The MIC was 25 mg/ml for Bacillus cereus and 58 mg/ml for Escherichia coli and the MBC values were 400 and >400 mg/ml respectively for the mentioned species. Overall, results presented here suggest that the methanolic extract of Echinops robustus possesses antibacterial properties, and is, therefore, a potential source of active ingredients for food and pharmaceutical industry.

“…There are few researches on the antimicrobial activity of Echinops genius. Şapci and Vural (2018) studied antimicrobial and antioxidant activity of Echinops antalyensis [5]. The research of Gemechu et al (2016) was on the antimicrobial activity of Echinops kebericho against human pathogenic bacteria and fungi [6].…”

Drugs based on plants of the Asteraceae family are broadly used against microorganisms that are pathogenic to people and animals. However, their potentials in this aspect have not been fully researched. In our in vitro experiment, we tested alcohol tinctures of 12 species of plants of the Asteraceae family against 10 species of bacteria, one species of fungi, and the larval stages of three species of nematodes – parasites of ruminants (L1 Muellerius capillaris, L1–3 Strongyloides papillosus, L3 Haemonchus contortus). The growth inhibition zone larger than 8 mm was observed after using ethanol extracts of the aboveground parts of several plants against the colonies of various microorganisms: Solidago canadensis showed activity against five species – Klebsiella pneumoniae, Proteus mirabilis, Shigella flexneri, Clostridium perfringens, and Candida albicans; Cyclachaena xanthiifolia was effective against five species – Escherichia coli, P. mirabilis, Enterococcus faecalis, C. perfringens, and C. albicans); Jurinea arachnoidea inhibited four species – K. pneumoniae, P. mirabilis, Pseudomonas аeruginosa, and Bacillus subtilis); Scorzoneroides autumnalis acted against four species – P. mirabilis, Sh. flexneri, C. perfringens, and C. albicans; Helichrysum arenarium demonstrated activity against four species – P. mirabilis, Sh. flexneri, E. faecalis, and Listeria monocytogenes; and extracts from the fruits of Echinops ritro were active against four species – K. pneumoniae, P. mirabilis, Staphylococcus aureus, and B. subtilis, while extracts from the flowers of Echinops ritro were effective against four microorganisms – K. pneumoniae, P. mirabilis, Sh. flexneri, and Р. аeruginosa. However, we observed no expressed nematocidal action of ethanol extracts of the studied species of plants. After 24 h exposures to 0.1% solutions of those extracts, over 95% of the nematode larvae of ruminants were found to be vital. Nonetheless, as a result of the study, those plants were recognized the most promising for further in vivo research of antibacterial activity. During the search for antibacterial and antifungal activities, the following plants were found to be the less promising: the aboveground parts of Artemisia austriaca, Lactuca serriola, Ambrosia artemisiifolia, Solidago virgaurea, roots of Artemisia vulgaris, Echinops ritro, Lactuca serriola, Solidago canadensis, Ambrosia artemisiifolia, Scorzoneroides autumnalis, and leaves of Echinops ritro.

Echinops kebericho Mesfin is wild endemic medicinal herb to Ethiopia and the root is used traditionally for the treatment infectious and non-infectious diseases. This study was designed to identify and quantify the phenolic compounds and in vitro antioxidant activity of the root extracts. Seven phenolic acids, six flavanols, and two aliphatic organic acids were analyzed by high performance liquid chromatography-diode array detector (HPLC-DAD), among which hydroxycinnamic acid (413.14 ± 6.60 µg/g), quercetin-3-O-galactoside (7.07 ± 0.34 µg/g) and succinnic acid (702.95 ± 42.54 µg/g) were the major components. The methanol extract exhibited the highest total phenolics (29.14 ± 0.38 milligram gallic acid equivalent gram of dried extract), total flavonoid content (1.08 ± 0.03 milligram of quercitin equivalent/gram of dried extract), and antioxidant activities followed by ethanol and water extracts. Antioxidant capacity were 99.96 ± 7.53µg/mL and 246.88 ± 15.60µg/mL as determined by the DPPH (IC50), ferric reducing power (IC50) assays, respectively. Total phenolic content (TPC) and total flavonoid content (TFC) were strongly correlated with DPPH (R 2 = 0.93, R 2 = 0.91) and ferric reducing power (R 2 = 0.98, R 2 = 0.71), respectively. The study revealed that crude root extract of E. kebericho can be used as natural antioxidants as well as for preventing oxidative stress mediated human disorders.
