Usually, plant phenols are best extracted with solvents like methanol and ethanol. But I would like to know if the extraction is carried out with water, how much usually is the efficiency of that extraction??
It depends on the composition of the plant material that you are using. Extraction is simply determined by the polarity of the substance that you are aiming to extract.
Phenolic compounds extracted from plant act as secondary metabolites which have strong Phytochemical and Pharmacological actions.
For analysis of efficiency of extraction, polarity is the matter of that substance.
I thing their are several methods of extraction of plant phenol i.e. liquid liquid extraction,ultrasound assisted extraction,microwave assisted extraction,supercritical fluid extraction.
As per my opinion you can goes to microwave technology in which water is used as solvent for to increase the speed and efficiency of extraction of phenolic compound from plant materials.
In this subject, according to the different type of secondary metabolites, published reports, available standards and the techniques of isolation and identification of the various types of possible phenolic compounds should be commented and interpratated.
In this experiment to isolate phenol I thing better to isolate by dry the aqueous extract then take phenolic component wth ethyl acetate solvent and then purify using coloumn chromatography
alcohols like methanol and ethanol are the best solvents to extract phenolic compounds. but these can also be extracted with water but it depends on the part of the plant drug used (leaves, flowers, roots ........) you must also do a bibliographic research on the optimization of the various extracts used on your plant in order to obtain the best yield in polyphenols. good luck
