Infrared spectrum of (a) noscapine: sharp bands between 700-1500 cm−1 which are mainly assigned to deformation and stretching vibrations of the alkaloid ring system and C=O stretch at 1759 cm−1, (b) pure PLLA: C=O stretch 1756 cm−1, C–O stretch 1000-1300 cm−1, (c) NMNP-7.5: absorption bands for both PLLA and noscapine are observed (noscapine’s absorption bands are shown in transmittance mode due to subtraction between NMNP and noscapine spectra).
