Hi twistd, welcome to the Prince Forum.

That level has no
broken room links, so there are no secret paths to the rooms with those life potions.
There are five life potions and the prince can only reach one of those, namely the one to the right of the skeletons.
The other ones (near the top right of the level, near the lower right, near the lower left, and at the top left) are unobtainable.
In theory, it might be possible to (ab)use game glitches -
tricks - to reach one or more of the others, but the author (Kirill) only expects players to get one life potion.
