It is observed that at varying extraction pressures under isothermal conditions (60 C), the mean peak area of delphinidin-3-rutinoside was significantly higher than that of delphinidin-3-glucoside (p = 0.0224)
However at 80 C, the reverse was observed e the mean peak area of the latter was insignificantly higher (p = 0.3827) than that of the former. Therefore, it can be reasonably concluded that at 10e15 MPa, 60 C, the eggplant peel color extracts are rich in delphinidin-3-rutinoside.
