Magnetocaloric effect of four different spin-1/2 J{sub 1}-J{sub 2} Heisenberg hexagons has been studied in terms of adiabatic demagnetization. Four hexagons with different combinations of antiferromagnetic and ferromagnetic Heisenberg exchange interactions are considered. Level of frustration on those models is different. Studies on the magnetization process, nature of isentrops and properties of magnetocaloric effect have been carried out. Comparison of results on those models has been discussed.
