This work focused on synthesizing novel chrysophanol‐loaded composites with varied ratios of polycaprolactone/xanthan gum to enhance the release of chrysophanol. The characteristics of the obtained composites were analyzed by infrared spectroscopy, scanning electron microscopy, transmission electron microscopy, differential scanning calorimetry, rhermogravimetric analysis and dynamic light scattering methods. The xanthan gum/polycaprolactone/chrysophanol (XPC) composites were obtained in the powdery form with particle sizes ranging from 80–100 nm. The results of hydrophilic and hydrophobic tests of the composites were discussed. Chrysophanol, polycaprolactone and xanthan gum can interact and are compatible to each other. XPC composites exhibit high stability and don't cause the negative effect on cells. Additionally, the chrysophanol release and kinetic model of chrysophanol release from the XPC composites in different pH buffer solutions were investigated and evaluated. Using drug carriers such as xanthan gum and polycaprolactone can enhance the release of chrysophanol in both pH 2.0 and pH 7.4 buffer solutions. In the presence of biopolymers, the distribution ability of chrysophanol in aqueous solutions such as pH 2.0 buffer, pH 7.4 buffer solutions, and 0.9 % NaCl solution was enhanced significantly. This will be favorable for an increase in the absorption of chrysophanol in the human body. [ABSTRACT FROM AUTHOR] |
