Phenolic contents and antioxidant activity of barhi date palm (Phoenix dactylifera L.) kernels extracts

Consumption of foods rich in phytochemicals with potential antioxidant properties can reduce the risk of various degenerative diseases such as cancer, atherosclerosis, diabetes, and aging. Several plant materials have been studied as sources of potentially safe natural antioxidants such as vegetable...
