#### Abstract

During the preparation of Ssang Wha tea it was observed that the highest yield was obtained when it was extracted with 50% ethanol, of which guantity was added 10 times more then that of Sample. The most effective extraction temperature and time was $90^{\circ}C$ and 8hours on the water bath, which was resulted in saving of production cost. From the HPLC Analysis, it was also observed that product extracted with 50% ethanol give higher yield than that of exfrac ted with water.
