| Abstract: | This study presents operating factors affecting yield of total phenol and ferric reducing antioxidant power (FRAP) value of extracts from lotus rhizome using orthogonal design experiment (L9(34)) based on single factor experiments. Optimum extraction conditions on yield of total phenol and FRAP value, respectively, were found as follows: ratio of material to liquid, 1 g: 6 ml, 1 g: 8 ml; extraction temperature, 70oC, 50oC; extraction time, 2 h, 0.5 h; and ethanol concentration, 40%, 40%. |
