Optimum extraction conditions with PWE were selected as 65–
212 lm for particle size, 40 C for temperature, 5 min for static
time, 5% for flush volume, and 2 extraction cycles for subsequent
experiments. A literature method with minor changes was applied
for the extraction of polyphenols in pomegranate peels (Singh
et al., 2002). Fig 3 shows the results of PWE and magnetic stirrer
extraction of pomegranate peels. The highest TPC was observed
with methanol extraction while the lowest was with ethyl acetate
extraction using the magnetic stirrer extraction method that was
in accordance with literature values (Singh et al., 2002). There
was no statistical difference between the results of PWE and methanol
extraction.
