In the present study, methanolic extract of peel, pulp and peel fiber from underutilized fruits of Citrus hystrix and C. maxima (red and white variety) were examined phenolic content and antioxidant activity systems. The extracts were also analyzed for α-amylase, α-glucosidase, cholinesterase and tyrosinase inhibition using properties. The major bioactive compounds responsible for all these bioactivities were documented as gallic acid, p-coumaric acid, chlorogenic acid, catechin, rutin, caffeic acid, trans cinnamic acid, ferulic acid, quercetin and ellagic acidthrough HPLC analysis. Higher inhibition of 79 and 71% against α-amylase and α-glucosidase respectively was registered by peel and peel fiber extract of both the C. maxima varieties.On the other hand, peel and peel fiber extract of C. hystrix showed higher inhibition rates of 64% towards both acetylcholinesterase and tyrosinase. The findings of this study explores the potential of underutilized fruits C. hystrix and C. maxima use of peel, pulp and peel fiber in supplementing human health.
