Screening in vivo antioxidant and haematological properties of sumac and acorn bioactive rich extracts

Sumac (Rhus coriaria L.) and acorn (Quercus brantii Lindl.) are plant species widely used in the Mediterranean countries for various industrial, therapeutic and nutritional purposes. This study aimed to investigate the phytochemical composition (phenolics, volatiles, fatty acids, and minerals) and effects of the extracts obtained from sumac and acorn on antioxidant mechanisms in various tissues (lung, spleen, hearth, and muscle) and several haematological parameters. Bioactive rich extracts containing phenolics (gallic acid and methyl gallate), volatiles (β-pinene, octanal, limonene, nonanal, β-caryophyllene, and humulene), fatty acids (oleic, palmitic, and linoleic acids) and mineral compounds (K, Mg, Ca, Si, Na, and B) regulated the levels of lipid peroxidation and antioxidant defence systems, and haematological parameters effectively.
