Abstract
ABSTRACT
The present study aimed to investigate the phytochemicals constituent of water and ethanolic extracts of barley leaves at 15 and 20 day old sprout. Also, evaluated the protective effect of these extracts against the blood lipid profile levels in high fat diet (HFD) of experimental rats. Finally, histopathological evaluation of liver , kidney , heart and aorta were performed. The phenolic compounds content in barley leaves aged 15th day of germinated were found to be 5425.4 and 7237.6 mg GAE/100 g, for both water and ethanol extracts while, in barley leaves aged 20th day of germinated of water and ethanol extracts were 5960.4, 8792 mg GAE/100 g. However, total flavonoids (TF) of both water and ethanol extracts of barley leaves aged 15th and 20th day of germinated were found to be (83.82 and 145.2 mg QE/100 g) and (167.9 and 191.8 mg QE/100 g) of DW, respectively. While, the antioxidant activity in the germinated barley for both water and ethanol extracts aged15th day showed 55.68 and 67.16% for (DPPH) and were found to be 77.68, 42.21% for (ABTS). However, barley leaves both water and ethanol extracts aged 20th day of germinated were 65.66 and 68.84% for (DPPH) and for (ABTS) were 79.33 and 52.30 %, respectively. Total carotenoids content were found to be (0.064, 0.072, 0.185 and 0.134 mg/100 g) but β-glucan contents were found to be (9.16, 5.47, 1.89 and 1.2 μg/mL) for water and ethanol extracts of barley leaves aged 15th and 20th day of germination, respectively . sixity rats used for Biological Experiment to study the effect of different barley le
