A Brief Review of Multiple Phytochemical Activities on Blackberry Leaves

Blackberry leaves are not considered functional foods, despitethe fact that they also have activesubstances with the potential to improve health. Blackberry fruits are recognised as functional foods. Blackberry (Rubus sp.) fruit has a strong antioxidant capacity and other biological activities becauseit includes significant levels of anthocyanins and other phenoliccompounds, primarily flavonolsand ellagitannins. It is well recognized that genetics, growingenvironments, and maturation affect the content and quantities of phenolic compounds in blackberries. Despitewhat is currentlyknown about theirchemistry, specialized studieson the health advantages of blackberry phenoliccomponents, metabolism, bioavailability, and mechanism by which they bestow health advantages is rare. Age-related neurological diseases are protected against by the phenolic compoundsin blackberries. Low-density lipoprotein and liposomal oxidation can be inhibited in vitro, alongwith illnesses and bone loss in vivo. Extracts of blackberries have also acted as an inhibitor of tumor- promoting factors and cell signalling pathways to exhibitantimutagenic actions in vitro and in animals. Blackberry phenolic compounds' anti-obesity, anti-diabetic, anti-microbial, and anti- inflammatory effects, however, require investigation. Likewise, investigations that clarify the physiologically effective quantities of phenolic chemicals found in blackberries in vivo are required.
