Abstract

The objective of this study was to analyze the total phenolics, total flavonoids, andantioxidant activities of Amaranthus spinosus L leaves. During cultivation, these plantswere treated with 2 treatments, biocontrol Effective Microorganism 5 (EM5) garlic andcontrol (water). The A. spinosus L leaves were dried using freeze dryer and extracted bydissolving n-hexane, dicloromethane (DCM) and methanol. The results showed thatA.spinosus L leaves treated with biocontrol had the highest total phenolic, totalflavonoid and antioxidant activity content compare to the control. The total phenolic,total flavonoid, 2,2 diphenyl-1-picrylhydrazyl (DPPH) and Nitric Oxide (NO) radicalscavenging were the highest on DCM extract with each value of 74,656 mg Gallic AcidEquivalent (GAE)/g of dry weight (DW), 22,337 mg Catechin Equivalent (CE)/g DW,0,373 mg/mL and 0,025 mg/mL. n-Hexane extract had the highest antioxidant activityon Ferric Thiocyanate ( FTC) test (27,615 %), meanwhile methanol extract indicated thehighest antioxidant activity on FRAP test (1,022 mmol Fe +2 /g DW). From this study,it can be concluded that A. spinosus L leaves with biocontrol EffectiveMicroorganism 5 (EM5) garlic can increase the phenolic, flavonoids and antioxidantactivitiy contents of A. spinosus L plant.
