In a living organism, free radicals occur within the cell during the normal metabolic process for various reasons. They are harmful to most biomolecules such as nucleic acids, proteins, carbohydrates and lipids. It causes diseases such as cardiovascular diseases, cancer and obesity. Substances that prevent the formation of free radicals, eliminate and neutralize the toxic effects they cause by scavenging the radicals in the environment are called “antioxidant substances”. Antioxidants play a vital role in both food systems and the human body to reduce the oxidative formation processes of reactive oxygen species and the harmful effects they cause. It has been determined by scientific studies that Morus alba, Morus rubra, Morus nigra plants contains a significant amount of bioactive substances and exhibits many different biological activities such as antimicrobial, neuroprotective antioxidant, antidiabetic, antiobesity, anti-inflammatory and anti-inflammatory.
