Why repeated extraction is better than solvent extraction?

Repeated extraction allows for greater efficiency in extracting desired components from a given sample due to the cumulative effect of multiple extraction cycles. This method ensures that more of the target compounds are effectively removed, leading to higher overall extraction yields compared to a single solvent extraction. Additionally, repeated extraction can help to overcome limitations such as incomplete extraction or low solubility that may be encountered with a single extraction.
