extraction of oil from plants is normally done through either distillation or "cold press" method.

distillation involves taking the plant material and boiling it up in water, the boiling water causes the cells to rupture releasing the oil, normally the oil is lighter and floats on the water where it can be removed and then further refined.

cold press method is simply putting the plants through a press where it is squashed to release the plant sap (including the oil), this is then refined to remove the debris and leave just the oil this method is used where high temperature could damage the oil.
