All rights reserved.The objectives of this research were to study antioxidant capacity of various fruit extracts from three varieties of tomato using two methods of antioxidant testing which were DPPH (2,2-diphenyl-1-picrylhydrazyl) and FRAP (Ferric Reducing Antioxidant Power) and correlation of total flavonoid, phenolic and carotenoid content in various fruit extracts of tomato with IC50 of DPPH and EC50 of FRAP antioxidant capacities. Extraction was performed by reflux using different polarity solvents. The extracts were evaporated using rotary evaporator. Antioxidant capacities using DPPH and FRAP assays, determination of total phenolic, flavonoid and carotenoid content were performed by spectrophotometry UV-visible and its correlation with IC50 of DPPH scavenging capacities and EC50 of FRAP capacities were analyzed by Pearson’s method. Ethyl acetate fruit extract of larisa variety (LA2) had the lowest IC50 of DPPH scavenging capacity (0.14 μg/ml) and the lowest EC50 of FRAP capacity was given by ethyl acetate fruit extract of amala variety (AM2) 46.9 μg/ml. Ethyl acetate fruit extract of larisa variety (LA2) contained the highest total phenolic (6.27 g GAE/100 g), n-hexane fruit extract of larisa variety (LA1) had the highest flavonoid content (5.13 g QE/100 g) and the highest total carotenoid content 58.74 g BE/100 g. There were negatively and high correlation between total phenolic content in fruit extracts of amala and larisa varieties with their IC50 of DPPH scavenging activities and EC50 of FRAP capacities. All of fruit extracts from three varieties of tomato 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,DPPH,Flavonoid,FRAP,Fruit,Phenolic,Tomato[/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]
