Unlike the green morphotype, which is widely utilized in culinary applications, the variegated (mixed red and green) morphotype has received considerably less attention as an edible vegetable. Furthermore, no validated extraction protocol has been established for this species, despite being a critical determinant of bioactive compound recovery. The present study therefore aimed to optimize extraction conditions and compare the phenolic profiles and antioxidant capacities of both morphotypes. Utilizing Box\u2013Behnken design (BBD)\u2010based response surface methodology (RSM), the optimized extraction conditions comprised 90% (\n                    <jats:italic>v\/v<\/jats:italic>\n                    ) aqueous ethanol, a shaking temperature of 50\u00b0C, an incubating time of 2\u2009h, and an extract concentration of 10\u2009mg\/mL. Under these conditions, the green morphotype exhibited higher total phenolic content (4.95\u2009mg gallic acid equivalent\/g dry sample weight (DW)), whereas the variegated morphotype exhibited higher total flavonoid content (31.95\u2009mg quercetin equivalent\/g DW) and total anthocyanin content (7.04\u2009mg cyanidin\u20103\u2010\n                    <jats:italic>O<\/jats:italic>\n                    \u2010glucoside equivalent\/g DW).

The green morphotype also demonstrated significantly higher ferric reducing antioxidant power (FRAP) and oxygen radical absorbance capacity (ORAC) activities, whereas 2,2\u2010diphenyl\u22121\u2010picrylhydrazyl (DPPH) radical scavenging activities were not significantly different between morphotypes.
