Evaluation of the Food and Nutrition Value of Rubus alceifolius Poir. Fruits of Mizoram, India

Background: Lesser known fruits and vegetables could be the source of dietary antioxidants and nutrition. However, to establish that these fruits and vegetables are important in healthy diet, it is imperative that thorough scientific investigations are performed. Results and data from such studies can also help in framing their conservation policy as well as in their promotion. Objectives: The present study reports for the first time the physicochemical properties, functional and antioxidant activities of the wild berry fruit Rubus alceifolius Poir collected from Mizoram, India. Methods: The average size, pH, juice content, the fruit acid content and dry matter content were determined. The antioxidant components of the fruit extract such as anthocyanin, β-carotene, lycopene, total phenolic and flavonoid contents were also reported. Results: The SPF number of the fruit calculated from Mansur’s equation was found to be 1.59 ± 0.03. HPLC analysis of the fruit extract for phenolic acids showed the presence of ellagic acid and gallic acid in the acetone-extract. Conclusion: Results from studies on various antioxidant activities such as DPPH scavenging, reducing capability and inhibition of lipid peroxidation indicate that the R. alceifolius fruit possesses antioxidant activities and its consumption may help in reducing the oxidative stress and preventing the various degenerative diseases associated with it.
