This method involves the use of a solid stationary phase, which selectively retains certain compounds from the liquid mobile phase, allowing for the separation of contaminants from the desired components.

Principle of SPE:
The principle of solid-phase extraction is based on the affinity of different compounds for the solid phase. The stationary phase is typically composed of a porous material with a specific chemical functionality, such as silica, alumina, or polymer-based resins. When the ethanol extract is passed through the SPE column, the target compounds are selectively adsorbed onto the solid phase, while other components pass through.

Procedure:
1. Conditioning: The SPE column is first conditioned with a suitable solvent to activate the stationary phase and remove any residual contaminants.
2. Sample Loading: The ethanol extract is then loaded onto the column. The target compounds are adsorbed onto the solid phase, while other components are eluted.
3. Washing: After loading, the column is washed with a solvent to remove any remaining impurities that are not adsorbed onto the solid phase.
4. Elution: Finally, a suitable eluent is used to elute the target compounds from the solid phase, resulting in a purified extract.

Advantages of SPE:
- High Selectivity: SPE can be tailored to selectively retain specific compounds based on their chemical properties.
- Simplicity and Speed: The process is relatively simple and can be completed in a short amount of time.
- Low Sample Volume: SPE can handle small sample volumes, making it suitable for precious or limited samples.
- Recovery: High recovery rates of the target compounds can be achieved.

Disadvantages of SPE:
