Abstract
|
|
|
|
This study was conducted in order to establish the optimum extraction conditions in obtaining Saururus chinensis extracts. At the optimum extraction solvent (40% ethanol solvent), yield, DPPH, total phenolic compounds and total flavonoid in the extract of Saururus chinensis were 13.50%, 83.50%, 2.60mg/ml and 2.09mg/ml, respectively. At the optimum extraction time (4 hours), yield, DPPH, total phenolic compounds and total flavonoid in the extract of Saururus chinensis were 12.79%, 71.13%, 2.83mg/ml and 2.16mg/ml, respectively. At the optimum conditions (40% ethanol solvent and 4 hours), quercetrin and quercetin contents were 360.13mg/100g and 1379.54mg/100g, respectively. From the above results, we suggest that the optimum Saururus chinensis extract conditions are 40% ethanol solvent and 4 hours.
