MetadataShow full item record
The bidara laut (Strychnos ligustrina) exhibits antioxidant activity. The objective of this study is to determine the highest antioxidant activity, total phenol, and bioactive compound analyzed using gas chromatography-mass spectrometer (GCMS) of the extract of bidara laut tree. Antioxidant activities was determined by radical scavenging assay using 1,1-diphenyl-2-pycryl-hydrazyl radical. The result showed that the highest of antioxidant activities is the wood methanol extract with IC50 value of 148.14 mg L-1. After partition using n-hexane the IC50 value was 103.14 mg L-1 and of butyl hydroxyl toluene which was used as control positive showed IC50 value of 10.86 mg L-1. The total phenol was determined using Folin-Ciocalteau method and resulted 1936.844 mg kg-1 dry sample. The result of compound analysis using GCMS showed that bidara laut contain phenolics with the major content is 1,2,3-benzenetriol, which is 2.66% (RT 10.77).
