A solid preparation of phytochemicals: Improvement of the solubility and bioavailability of Astragaloside IV based on β-cyclodextrin microencapsulation
Abstract:Astragaloside IV/β-cyclodextrin inclusion complex(AsIV/β-CD IC) was successfully prepared by low-temperature sedimentation technology. Under the preparation conditions inclusion temperature 60℃, inclusion time 3h, core-wall material molar ratio 1:1, and inclusion rate 750 rpm, the optimal encapsulation efficiencyreached 81.63%. It was characterized by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), X-ray diffractometer (XRD) and thermogravimetric (TGA). Physicochemical c… Show more
