The reflux method was found to be better than the decoction method and the highest yields of baicalin and puerarin were obtained from the reflux method with 60% ethanol as the extraction solvent fig 5. Reflux method of extraction. Reflux this is the original eden labs extraction method known as “coldfinger” extractiona basket of herb is suspended beneath an inverted condenser which is designed to have multiple drip points so that condensed solvent rains evenly across the basket for even extractionsolvent is placed in the bottom of the distiller and is vaporized through heat and/or vacuum.
reflux method of extraction
Check for the best solvent as either method would work, but extraction efficiency is more dependendet on solvent i would advise you to use water as a solvent and use a reflux condenser or a. The kettle has a capacity of 50-100 kg. flowers per batch and takes about 6-8 hours to complete the distillation. after distillation is over the receiver is removed and oil is separated. this method gives a recovery of 0.01-0.015% which is significantly lower than the other methods described below. 2..
