Abstract:
Jackfruit (Artocarpus heterophyllus Lam) is considered to be the largest tree-borne fruit in the world. The present study was undertaken to analyze the potential of non-edible jack fruit parts as an inexpensive and readily available resource of bioactive compounds. Extraction procedure for maximizing the antioxidant, anti-cancerous, and anti-hyperglycemic properties of non-edible fruit part from varikka (firm flesh type). Non-edible parts of the firm fleshed jackfruit type (varikka) were dried and used for the estimation of total phenolic content (TPC), total flavonoid content (TFC), ascorbic acid content and antioxidant activity (DPPH scavenging activity). The extract had highest TFC (15.66 mg QE 100g^-1 DW) and DPPH scavenging activity (lowest IC₅₀ value 0.83) with superior TPC (156.10 mg GAE 100 g^-1 DW) and ascorbic acid content (41.90 mg 100 g^-1). Considering the efficiency and economics, freeze dried sample at 1:50 and 1:40 solid to solvent ratio and tray dried sample at 1:50 solid to solvent ratio were selected for exploring their potential as anti-hyperglycemic agent. A very strong correlation between TPC and TFC with α glucosidase inhibition activity of the extracts was seen revealing the potential of non-edible part of jackfruit as the promising source of antioxidants and α-glucosidase inhibitors.
