The study was aimed to investigate the use of microwave assisted extraction (MAE) to improve the extraction efficiency of the Polyphones from crude drugs. Classical solvent extraction techniques have several limitation especially low yield and time consumption; hence the present study was designed to provide an effective alternative method of extraction which can be adopted at industrial level. In this study poly-phenol were extracted from Harda (Terminalia chebula) using Soxhlet and microwave apparatus, and effectiveness of the both process was evaluated by determining tannin concentration. The method selected for tannin estimation was Folien-ciocalteu method. Result of the study clearly demonstrated that microwave is better method. Study had also undertaken the task of optimization of parameters such as solvent type, microwave power, extraction time and temperature. Results had revealed that the best possible combination parameter for fast and highest extraction by this method was found to be 2 Power of microwave, 50°C temperature, 4 min. time and alcohol as solvent.
