Optimal Solvent Design for Antioxidant Extraction Process from Bamboo Leaves Using Solubility Parameters
Abstract
To extract the antioxidant functional natural pigment chlorophyll a from bamboo leaves, the optimal solvent was selected using the solubility parameter. A central composite design-response surface methodology (CCD-RSM) was employed to determine the optimal extraction conditions. The independent variables included the solvent's solubility parameter and extraction temperature. The response variables were defined as antioxidant activity, assessed by full name 필요(DPPH) radical scavenging activity, and target color coordinates ( = 51.8, = -20.3, = 35.9). The optimal extraction conditions obtained through CCD-RSM optimization were a solubility parameter of 19.8 and an extraction temperature of 32.5 °C. Under these conditions, the predicted response values were DPPH radical scavenging activity = 60.9%, and = 50.9, = -20.2, = 35.9. The actual experimental results measured DPPH radical scavenging activity = 65.3%, and = 50.5, = -20.1, = 35.6, with an average error rate of ± 2.2%.
