摘要: Use of dimethyl sulfoxide (DMSO) as a suitable extraction solvent under the optimum conditions microwave assisted (MAE) prior to total phenolics determination and antioxidant activity assay was conducted. The MAE method done with 0.05 g sample in 10 mL DMSO at 500 W within 5 min. effects on various activities using DPPH(·+), DMPD(·+), ABTS(·+) FRAP, Folin-Ciocalteu reagent were investigated. From results, it is clearly demonstrated that itself shows no effect any those assays including content. extracts 14 local chilli varieties gave their following ranges: DPPH, 3.07-20.0; DMPD, 1.52-6.61; ABTS, 20.4-56.0; 8.98-42.1 mg GA/g DW. Their contents found range 53.7-200 mg This study demonstrates most for antioxidants from chilli. In addition, analysis data obtained among four respect highly significant positive regression coefficient (r > 0.92), indicating are primarily responsible extract.
