(A) Release profiles of physical mixture of protocatechuic acid with Mg/Al-layered double hydroxide. (B) Release profiles of protocatechuic acid from PANE at pH 7.4 (a), pH 5.3 (b), and pH 4.8 (c). (C) Release profiles of protocatechuic acid from PAND at pH 7.4 (d), pH 5.3 (e), and pH 4.8 (f). Insets show the release details.
