All rights reserved.The aim of this research were to measure antioxidant activity from different polarities leaves extracts of five citrus using two methods of antioxidant testing which were DPPH (2,2-diphenyl-1-picrylhydrazyl) and FRAP (Ferric Reducing Antioxidant Power) and correlation of total phenolic, flavonoid and carotenoid content in different polarities extracts of citrus leaves with their IC50 of DPPH and IC50 of FRAP antioxidant activities. Extraction was performed by reflux using different polarity solvents. The extracts were evaporated using rotary evaporator. Antioxidant activities using DPPH and FRAP assays, determination of total phenolic, flavonoid and carotenoid content were performed by UV-visible spectrophotometry and its correlation with IC50 of DPPH scavenging activities and EC50 of FRAP capacities were analyzed by Pearson’s method. All of different polarities leaves extracts of C. reticulata, C. maxima, C. limon, C hystrix and C. aurantifolia (except n-hexane extract of C. hystrix, n-hexane extract of C. aurantifolia and ethanolic extract of C. maxima) were very strong antioxidant, using DPPH assays. Phenolic compounds in C. aurantifolia leaves extracts were the major contributor in IC50 of DPPH scavenging activity and EC50 of FRAP capacity. Leaves extract of C. hystrix and C. aurantifolia had linear result in DPPH and FRAP assays.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Antioxidant,Carotenoid,Citrus leaves,DPPH,Flavonoid,FRAP,Phenolic[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
