Microcapsules containing Pterodon pubescens Benth. extract with cashew gum as wall material

Abstract

Pterodon pubescens Benth. (Leguminosae) is a native plant found in central Brazil, commonly known as Sucupira, widely used in traditional medicine. The species has been reported to have antiproliferative, anti-inflammatory and analgesic properties [1,2]. The technique of encapsulation by spray drying allows obtaining microcapsules with sizes ranging from 0.2 to 500.0 µm, providing protection of the plant extract, which can be altered by exposure to oxygen, moisture, light and other components in a formulation. In this process, the first step is the selection of an appropriate wall material.
