In terms of yield, the repeated extraction technique is more efficient.

The residue left over after extraction contains the same amount of material as the extract itself. If you extract again, both the concentration in the extract and the residue will be decreased.

Therefore, with several extractions, there will be less material left in the residue, meaning the extraction will be more thorough.
