1- Collection the required part of the plant.

2- Wash with tap water

3- Dry under shade.

4- Grounding ( make it powder)

5- Extract with different solvent, starting from non-polar ( hexane, ethyl acetate,

methanol and 70% methanol.

6- First extract ( hexane is oils and oily compounds).

7- Take TLC for next two extracts, to know the number of components.

8- Evaporate the solvents by rotary evaporator,

Next step is related to What you want ( single pure compounds or used as extract.

9- Separate pure single compounds using chromatography ( the best one is MPLC

flash chrom.) or column chrom.

10- Evaporate the solvents by rotary evaporator.

11- Apply the separated compounds according to your need.

Mam, you can also try with sequential ombinations of extraction using Soxhlet, microwave, ultrasonic, supercritical, or maceration methods to ensure complete extraction.
