I wouldn't allow it.
By the rules, they're not potions. More importantly, there's a balance issue. An alchy's extracts are not potions in that they don't cost money and aren't limited to level 3. They're a lot more powerful because of that.
It's okay if a barbarian can use potions as move actions since if you're using them all the time, you're going to pay a lot of gold for this. So you'll probably limit this.
The alchy uses them all the time.
