Phytochemical Profile

Abstract Background Many recent studies have shown that medicinal plants, which have been used worldwide through the past history in the folkloric medicine, harbor a significant number of novel metabolic compounds with potent pharmacological properties. In several countries, the aerial parts of the Scolymus angiospermus plant have been used as a food supply and as a folkloric medicinal plant. The current study aimed is to investigate the antimicrobial, antilipase, antioxidant activities and phytochemical profile of methanolic, hexane, aqueous and ethyl acetate fractions obtained from the aerial parts of S. angiospermus. Methods Phytochemical assessments were based on standard analytical methods. The obtained fractions were evaluated for their antioxidant capacity and their antilipase activity using 2,2-diphenyl-1-picrylhydrazyl and porcine pancreatic lipase inhibitory tests, respectively. Antimicrobial activity of the obtained fractions was evaluated using broth microdilution assay against several American Type Culture Collection bacterial and fungal strains and Methicillin-Resistant Staphylococcus aureus clinical isolate. Results Our data showed that of all obtained fractions used in the above-mentioned assays, both of methanolic and aqueous fractions, had the highest content of flavonoids (24.93 ± 2.11 and 12.21 ± 2.11 mg QUE/g, respectively) and phenolic compounds (96.28 ± 2.87 and 91.25 ± 2.63 mg of GAEq/g, respectively) as well as the best levels of both antioxidant (half maximal inhibitory concentration (IC50) 13.67 ± 1.44 and 14.69 ± 1.97 µg/ml, respectively) and antilipase (IC50 134.89 ± 1.65 and 269.15 ± 2.33 µg/ml, respectively) activities. In addition, these fractions exhibited various levels of both antibacterial and antifungal activities. Hydrophilic fractions were more potent against the investigated bacterial strains, while hydrophobic fractions were more potent against the investigated fungal strains. Conclusions The hydrophilic fractions derived from S. angiospermus have shown the best antioxidant and antilipase effects. This is may be due to the high contents of phenols and/or flavonoids. However, further investigations are essential to isolate and identify the antioxidant, antilipase and antimicrobial compounds. Our data provide significant evidence that S. angiospermus can be very useful in the prevention and treatment of various infectious and non-infectious chronic diseases and as natural food preservatives.
