  This paper studies the log-convexity of the extended beta functions. As a
consequence, Tur\'an-type inequalities are established.The monotonicity,
log-convexity, log-concavity of extended hypergeometric functions are deduced
by using the inequalities on extended beta functions,. The particular cases of
those results also gives the Tur\'an-type inequalities for extended confluent
and extended Gaussian hypergeometric functions. Some reverse of Tur\'an-type
inequalities also derived.
