. Aqueous extraction process was performed
in a temperature controlled water bath and distilled water was
used as a solvent under different aqueous extraction conditions
(extraction temperature (40–60 ˚C), time (20–100 min)
and solid–liquid (SL) ratio (1:5–1:15 g/ml). Different solid–
liquid ratios of samples (1:5, 1:10 and 1:15) were taken in
150 ml Erlenmeyer flasks and it was incubated at different
temperature (40, 50 and 60 ˚C) in a temperature controlled
water bath. Extracts were taken at different time intervals (20,
60 and 100 min).
