Fig. 3

Structural characterization of pullulan-lovastatin (PLV) conjugates. a FTIR spectra for pullulan, LV, PLV (1/2), PLV (1/3), and PLV (1/4), peaking at 1644, 1642, and 1648 cm−1 as characteristic peaks of pullulan. The dotted lines at 1360, 1459, and 1725 cm−1 show the bending vibration peaks of –CH3– and –CH2– for LV. b 1H NMR spectra for pullulan, LV, PLV (1/2), PLV (1/3), and PLV (1/4)
