  We calculate the jet quenching parameter in medium with chemical potential
from AdS/CFT correspondence. Our result is summarized in a plot. Moreover, we
extract the explicit form of the jet quenching parameter of medium with small
chemical potential for phases of dual SYM corresponding to large and small
black holes. For the former phase, the jet quenching is increased as the charge
density increases, however, for the latter it is the opposite though the
background is thermodynamically unstable.
