Analysis of anti-tumor active components and preparation of self-assembled polymeric micelles in <i>taxus chinensis</i> seeds
Abstract
OBJECTIVE: seeds, which was combined with TPGS and mPEG-PCL to make micelles, improve its solubility and anti-tumor activity, and reduce the toxic side effects. METHODS: solvent injection combined with TPGS and mPEG-PCL and optimized using the single-factor screening experiment. RESULTS: BE-M were spherical micelles with particle size (34.37 ± 0.11) nm and polydispersity index (PDI) 0.152 ± 0. 003, possessing a high encapsulation rate (86.53 ± 1.54) % and drug loading (21.63 ± 0.87) %. The critical micelle concentration (CMC) value was very low at 0.881 μg/mL, indicating that BE-M has good stability. X-ray diffraction analysis (XRD) and Fourier transform infrared analysis (FT-IR) showed that BE had been successfully encapsulated in BE-M. CONCLUSION: anti-tumor effect of BE.
