Dear Akram A. Albaidhani, ethanol is the most used solvent. If you use soxhlet extractor, concentration is meaningless, rather the number of cycles is. My Regards

Hi Akram,

Ethanol is one of the most commonly used plant extraction solvents. It is a polar solvent with good solubility and extraction ability. Due to its low volatility, ethanol can effectively avoid the loss of nutrients during the volatilization process and is suitable for the extraction of various plants.

Glycerol is also one of the commonly used plant extraction solvents. It is a polar solvent that can effectively extract nutrients from plants, with minimal impact on the plant itself during the extraction process. Glycerol is commonly used for the extraction of plant traditional Chinese medicine.

Ethyl acetate is a polar solvent with high solubility, suitable for the extraction of high-fat plants.

Dear Abdelkader BOUAZIZ,

Thank you for your response. I will try to use this extraction method next time.

Best regards

Hi Chen Jingwen,

Thanks for the clarification. Among the three solvents you have stated above, which one is more effective and suitable to assess the antibacterial activity of plant extracts?

I'm interested in hearing more about your thoughts.

Best regards and wishes
