Microwave Assisted Extraction of Phyllanthus amarus

چکیده
2. Soxhlation: Soxhlet extraction is only required where the desired compound has a limited solubility in the solvent, and the impurity is insoluble in that solvent. If the desired compound has a high solubility in a solvent then a simple filtration can be used to separate the compound from the insoluble substance [1]. In a conventional soxhlet system plant material is placed in thimble-holder, and filled with condensed fresh solvent from distillation flask. When the liquid reaches the overflow level, a siphon aspirates the solution of the thimble-holder and unloads it back into the distillation flask, carrying extracted solutes in to the bulk liquid. In the solvent flask, solute is separated from the solvent using distillation. Solute is left in the flask and fresh solvent passes back in to the plant solid bed. The operation is repeated until complete extraction is achieved. This method cannot be used for thermolabile compounds as prolonged heating may lead to degradation of compounds [3].
