It has many vitamins, proteins, and mineral matters in its composition. Many Ribes types, especially black ribes types with darker fruits contains polyphenolic compounds in high concentrations, especially due to their antioxidant activities they have increasing amounts of anthocyanins and flavonols that are increasingly sought after due to their antioxidant activities. The most significant anthocyanin found in black ribes are cyanidine-3-glucoside, cyanidine-3-rutinoside, delphinidine-3-glucoside, and delfinidine-3-rutinoside. Natural antioxidants have protecting the body against infections, preventing anemia by inhibiting decomposition of red blood cells, preventing synthesis of cancerous compounds, diluting the blood by increasing prostaglandin synthesis (antithrombotic effect), preventing arteriosclerosis, and preventing unwanted effects on metabolism of active forms with oxidation ability causing liver damage. Its protective effects such as healing effects on some cancer types are known. Level of Catalase (CAT) was found to be 0.00011 U/mI on average for fresh ribes. Level of Superoxide Dismutase (SOD) was found to be 11.6960 U/mI on average for fresh ribes. The level of Reduced Glutathione (GSH) was found to be 0.00011 mmol/dI on average for fresh ribes. In this study ribes was found to display a very strong antioxidant activity. Thus, ribes was demonstrated to be a protective antioxidant against oxidative damage against many diseases.
