All rights reserved.Objective: The aims of this research were to determine antioxidant activity from various herbs extracts of three kinds of lemon grass using two antioxidant testing methods which were 2,2-diphenyl-1-picrylhydrazyl (DPPH) and ferric reducing antioxidant power (FRAP) and correlation of total phenolic content (TPC), total flavonoid content (TFC), and total carotenoid contents (TCC) with their inhibitory concentration 50% (IC50) of DPPH and exhibitory concentration 50% (EC50) of FRAP. Methods: A sample was extracted by reflux method using different polarity solvents. The extracts were evaporated using rotary evaporator. Antioxidant activities using DPPH and FRAP assays, determination of TPC, TFC, and TCC were carried out by ultraviolet -visible spectrophotometry and correlation with their IC50 of DPPH and EC50 of FRAP capacities were analyzed by Pearson’s method. Results: The ethanolic herbs extract of Cymbopogon citratus (CC) had the lowest IC50 of DPPH scavenging activity 2.75 μg/ml and the lowest EC50 of FRAP capacity 12.22 μg/ml. Ethanolic herbs extract of Cymbopogon winterianus exposed the highest phenolic content and its n-hexane extract presented the highest carotenoid content. Ethyl acetate herbs extract of CC gave the highest flavonoid content. There was significantly negative correlation between TPC in CC herbs extract with their IC50 of DPPH and EC50 of FRAP. Conclusions: All herbs extracts from three kinds of lemon grass were categorized as a very strong antioxidant by DPPH method. Phenolic compounds in CC were the major contributor in antioxidant activities by DPPH and FRAP methods. DPPH and FRAP gave linear result in antioxidant activities of herbs extract of three kinds of lemon grass.[/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]2,2-diphenyl-1-picrylhydrazyl,Antioxidant,Ferric reducing antioxidant power,Herbs,Lemon grass,Three kinds[/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]
