Jookrhyuk (Bambusae Caulis in Liqamen) was extracted at low temperature (100℃ - 160℃) and purified by adsorption and distillation and their physicochemical properties were compared. In case of colour among all Jookrhyuk samples the L value appeared to be higher in the purified Jookrhyuk,and the b value appeared to be higher in crude Jookrhyuk. Purified Jookrhyuk showed much lower level of total sugar and tar contents than crude Jookrhyuk. A considerable reduction in concentration of methanol and phenolic compounds was achieved by purification process, whereas the content of acetic acid was increased. Therefore it was suggested that adsoption and distillation could be used as one of effective purification methods of various Joockrhyuk samples.
