A X-ray powder diffraction patterns for (a) pure silymarin, (b) physical mixture, (c) lipid-polymer hybrid nanoparticles (LPNs), (d) silymarin-loaded LPNs (S-LPNs), and (e) chitosan-modified S-LPNs (CS-LPNs). B DSC curves of (a) raw silymarin, (b) physical mixture, (c) blank LPNs, (d) S-LPNs, and (e) CS-LPNs. C In vitro release profiles. Phosphate-buffered saline (pH 7.4) (containing 2% Tween 80) was used as the release medium. Data are presented as the mean ± standard deviation (n = 3)
