Abstract
The current study aimed to evaluate the phytochemical composition, quality control, and antioxidant, antibacterial, antifungal, antihyperglycemic activities, and toxicity assessment of Crataegus monogyna Jacq (C. monogyna) and Crataegus laciniata Ucria (C. laciniata) fruits aqueous extracts. The quality control of the plant material revealed that it is free of heavy metals and the acidity and ash parameters comply with international standards. HPLC-DAD analysis revealed the presence of eight phenolic compounds in the C. monogyna extract and nine compounds in the C. laciniata extract, with coumaric acid present only in the C. laciniata extract. According to the findings, both extracts are high in total polyphenols, total flavonoids, and condensed tannins. The results of the antioxidant activity revealed that our extracts have significant effects against 2, 2-diphényl 1-picrylhydrazyle (DPPH), and Ferric Reducing Antioxidant Power (FRAP). The antibacterial test revealed that the two extracts tested were effective against four bacterial strains, including Staphylococcus aureus, Escherichia coli, Enterobacter cloacae, and Shigella dysenteria, but were ineffective against Salmonella typhi, and Acinetobacter baumanii. In addition, extracts from both plants showed remarkable antihyperglycemic activity with no acute toxicity. In conclusion, the extracts studied could be a good source of bioactive molecules with antioxidant, antimicrobial, and anti-diabetic activity for pharmaceutical applications.
