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.

Jookrhyuk (Bambusae Caulis in Liqamen) is one of the most important ingredients for treating Diabetes mellitus. Various aspects of quality of Jookrhyuk produced in Korea depending on carbonization process were compared. The pH Value was the highest in Jinyoungsangsa Jookrhyuk(pH 3.17) among the three different Jookrhyuk samples. Damyangsan Jookrhyuk that contains high level of total sugars(8.0 Brix, %) show incresed level of tar contents, it exhibited positive realationship between total sugar and tar contents. Concentration of methanol and phenolic compounds which are related to toxicity were the highest in Damyangsan Jookrhyuk(1.34㎎/㎖, 3.84㎎/㎖ respectively). The harmful heavy elements were not found in the evaluated Jookrhyuk samples. In coclusion, it was suggested that Bambusae Caulis in Liqamen should be further puryfied for using as main oral medicines for treating Diabetes mellitus.
