Phytochemical compounds extraction from medicinal plants by subcritical water and its encapsulation via electrospraying

In this study, phytochemical compounds were extracted and encapsulated from medicinal plants such as M. oleifera, S. androgynus, and S. grandiflora using subcritical water and the electrospraying technique. The extraction was conducted at temperatures of 120 to 160 °C at various extraction pressures...
