Summary
Mulberry, a fast-growing deciduous plant, grows under tropical, subtropical and temperate climate. It is known for ages for its different applications. Leaves, bark and root have long been used in Chinese medicine to treat fever, improve eyesight, strengthen joints, protect the liver, facilitate discharge of urine and lower blood pressure. Nowadays mulberry leaves and theirs extracts, due to a strong antioxidant activity, are used to prevent and treat wide range of civilization disorders.
In the paper morphology, rich phytochemistry and antioxidant potential of mulberry leaves are characterized. Flavonoids from this plant, including quercetin, rutin and isoquercitrin, as a free radical scavengers, show the potential effect against oxidative stress. Thus, the chemoprotective effect of mulberry leaves is discussed. The review is focused on the some examinations of plant leaves and its extracts as a potent influence on cardiovascular diseases, especially inhibit LDL oxidation and prevent atherosclerosis. Diabetes, the new disorder of XXI century, could be prevented and treated by components of mulberry leaves. Numerous studies have reported that mulberry plant is effective against hyperglycemia and lipid peroxidation. Neuroprotective function of mulberry leaves extracts are also described. Last examinations show that mulberry leaves extracts have a promising skin whitening activities. Antibacterial and antiviral activities of mulberry leaves extracts are also characterized.
Key words: morus alba leaves, bioactive compounds, antioxidant activity, civilization diseases, pharmacological activity
