ABSTRACT
In this study, magnolol phospholipid complex (MPC) was prepared and solidified with polyvingypyrrolidone (PVPP). The influence of PVPP on MPC's flowability, dissolution and oral bioavailability was investigated. The results of phase characterization using differential scanning calorimetry (DSC), infrared spectroscopy (IR), and scanning electron microscopy (SEM) showed that magnolol existed in solidified powder and MPC in an amorphous state. In flowability and dissolution experiments, solidified powder showed significant superiority. At the same time, it showed a higher oral bioavailability compared with MPC, with AUC0-∞ of 73.47 μg•h•mL⁻¹ vs. 63.48 μg•h•mL⁻¹. This process for solidifying powder with PVPP is simple and convenient.
