The influence of extraction temperature and time on antiradical activity and total phenolic extract of Ceciwis
In Indonesia, cruciferous cabbage is known as Ceciwis (Brassica oleracea var. capitata alba), a vegetable that can be consumed as a diet. Ceciwis is a member of the Brassica family, which has been shown to have chemo-preventive action. The existence of antioxidant activity confirms its efficacy. The existence of antioxidant activity confirms its efficacy. Further research is required. Antioxidant activity will undoubtedly be affected by the extraction procedure and circumstances. The objective of this study was to examine antioxidant activity, DPPH radical scavenging, ABTS, and total phenol content in Ceciwis reflux extraction results as a function of temperature and extraction time. Ceciwis were washed after harvesting and then forced to submit to a reflux extraction process at temperatures ranging from 40 to 50 °C, 60 to 70 °C, and 80 °C, with extraction times, varies from 0.5 to 3.5 hours. The yield, total phenols, and radical scavenging of DPPH and ABTS were all examined in the condensed extract. The results of a four-response analysis revealed that ABTS radical scavenging was the most influential reaction to the temperature of the extract, accounting for 60.7%, followed by DPPH, yield, and total phenols, accounting for 50.7%, 26.16%, and 0.00%, respectively. The extraction period would have the greatest impact on the yield response and total phenols of 74.42 and 72.75%, respectively. The DPPH and ABTS reactions are unaffected by radical scavenging.
