I have started my industrial training . During the last week, I was put in charge of some machine called rotary evaporator and my job was to get the mangosteen skin extract . The mangosteen skins were first soaked in methanol (an alcohol) for days, filtered for the liquid and then only is it poured into the evaporator machine to get the extract.
