In vitro release profiles of emodin liposomes by dialysis against three media. (A) emodin liposomes against PBS (pH 7.4); (B) emodin liposomes plus equal volume of plasma against PBS (pH 7.4); (C) emodin liposomes against citrate buffer (pH 5.0).
Notes: (▲: mPEG2000–DSPE liposomal emodin; ◆: TPGS liposomal emodin); error bars refer to standard deviations, n = 3.
Abbreviations: PBS, phosphate-buffered saline; TPGS, D-α-tocopheryl polyethylene glycol 1000 succinate; mPEG2000–DSPE, methoxypolyethyleneglycol 2000-derivatized distearoyl-phosphatidylethanolamine.
