Formulation of Spray-dried Proliposomes Loaded with Berberin

Abstract

The aims of study was formulation and evaluation of berberin (BBR) loaded proliposomes by spray-drying method. BBR proliposomes were evaluated for appearance, spray-drying efficiency, morphology and differential scanning calorimetry (DSC). Liposomes, obtained after hydration, were evaluated for particle size, size distribution, morphology and entrapment efficiency. The results showed that BBR proliposomes were prepared by spray-drying method with molar ratio of Hydrogenated soy phosphatidyl choline (HSPC): Sodium deoxycholat (NaDC): vitamin E (vtE): BBR = 7: 1: 6: 6. Mixture of manitol and Aerosil at weight ratio of 97:3 was used as carrier. Results of DSC showed that berberin was dispersed molecularly into proliposomes powder. BBR liposomes, obtained after hydration, had average particle diameter of about 29 μm and entrapment efficiency was 22.23%.

Keywords
