2.4. Investigation of suitable method for extracting of S. collinsiae root
Different extraction methods were performed by accurately
weighing of dried powder of S. collinsiae roots and exhaustively
extracted with 70% ethanol, which was found to be the appropriate
solvent, by maceration, sonication, percolation, reflux, and Soxhlet
extraction. Maceration, sonication and percolation were performed
at room temperature (30–35 ◦C) under relative humidity of 73±6%.
