Preparation and surface morphology of herbal based polylactide microspheres

Polymeric microspheres from polylactide and infusion of Woodfordia fruticosa flower were prepared using emulsion-solvent evaporation method. The obtained microspheres were spherical to oval in shape with the size ranging from 1 to 29.8 µM with WFPM-2 yielding the major population within a range of 1-6 µm.
