(pH 2.0, using 6 M HCl). With a separatory funnel, the free phenolic compounds were extracted with diethyl ether (5 × 20-mL portions). The extractant was composed of acetone, water, and acetic acid. The organic phase (acetone) was removed using the
20 m m potassium phosphate (pH 2.5 by phosphoric acid) at a flow rate of 1 mL/min and were detected at 210 nm. L-Proline (Sigma) dissolved in the 20 mm potassium phosphate solution was used to calibrate the standard curve. The amount of proline in
of 5.8 ( Lien and Rognes, 1997 ); a pH increase from 3.5 to 9.2 causes a reduction in glycine uptake in Lolium perenne ( Thornton, 2001 ), and glycine uptake by Pisum sativum shows little change between pH 2 to 9 ( Dureja et al., 1984 ). Glycine
