| Abstract: |
| In this paper，two-phase separation principle of gutta percha was introduced: organic solvent could dissolve the gutta silk in plant fiber after mixing of organic solvent and comminuted eucommia ulmodies，the two-phase liquid could be obtained by using hot water to wash organic solution，in which the water phase took away the impurity of plant tissue. The following addition of ice-water to the organic phase after separation could get the settled gutta percha. Compared the petroleum ether and chloroform as organic solvents in the extraction process，the results showed that chloroform was more suitable for the extraction of gutta percha than petroleum ether. The gutta percha extraction device was designed based on the two-phase separation method，which also was improved according to the problems in use. |
