Abstract

Artocarpus heterophyllus seeds are available in larger quantity and are good source for many phytochemicals. The seeds are rich in proteins and low in fat content. The present study was carried out to analyse the phenolics, proteins and antioxidant activity of A. heterophyllus seeds. Different aqueous solvents such as acetate buffer pH 5.0, phosphate buffer pH 7.0, tris buffer pH 8.5, different concentration of sodium hydroxide (0.05M, 0.1M, 0.2M, 0.3M, 0.4M, 0.5M), sodium chloride, water and organic solvents like ethanol, methanol and acetone were used for extraction. Sodium hydroxide (0.1M) showed maximum extraction efficiency. Among the organic solvents, ethanol showed maximum phytochemical extraction. Different concentrations of ethanol (20%, 40%, 60%, 80%) containing 0.1M NaOH were also used for extraction and maximum extraction was found in 40% ethanol containing 0.1M NaOH. GC – MS analysis was carried to identify various bioactive compounds present in the extracts (hexane, ethyl acetate, methanol and water) of the seeds.
