Martin Guptill and Wes Durston scored centuries as Gloucestershire recovered from a poor start to take control against Gloucestershire.
The home side slumped to 29-2 early on as Will Madsen was trapped lbw by Will Gidman and Chesney Hughes was caught by Ian Cockbain off David Payne.
But opener Guptill led the fightback, scoring 25 fours in his 143.
Along with Durston (151 not out) he put on 266 for the third wicket before Derbyshire closed on 329-4.
That was a career-best score for Durston and came six years after his previous highest - 146 not out against Somerset.
