lista = RandomInteger[100, {15, 2}]

{{95, 25}, {63, 52}, {82, 59}, {43, 71}, {67, 73}, {79, 0}, {18,
   47}, {16, 24}, {16, 56}, {94, 88}, {92, 47}, {84, 77}, {92,
   82}, {36, 20}, {3, 31}}

{xmin, ymin} = Min /@ Transpose@lista
{xmax, ymax} = Max /@ Transpose@lista

{3, 0}

{95, 88}

or

range[x_List] := x[[Ordering[x][[{1, -1}]]]]
{{xmin, xmax}, {ymin, ymax}} = range /@ Transpose@lista

{{3, 95}, {0, 88}}
