Isolation and characterization of ginger PDNPs under different pH. (A) Experimental flowchart depicting the purification of ginger PDNPs under different pH conditions. (B) Photomicrographs of ginger PDNP pellets obtained by PEG precipitation of S10 extract under different pH. Pictures taken by the first author of this article. (C) Total yield of ginger PDNPs isolated under different pH conditions PEG precipitation. (D) Average size of ginger PDNPs isolated under different pH. (E) Average zeta potential of ginger PDNPs isolated under different pH. Results presented are average of four independent experiments. *P < 0.05 and **P < 0.01.
