Phytochemical constituents and antioxidant activities of banana flower of Musa x paradisiaca

Frequent consumption of fruits and vegetables is associated with a lowered risk of cancer, heart disease, hypertension and stroke. This has been attributed to the presence of various forms of phytochemical and antioxidants in the foods. Pisang Nipah (Musa x paradisiaca) was analysed in this study fo...
