| 中文摘要: |
| 介绍杜仲橡胶的两相提取分离原理：将有机溶剂与粉碎的杜仲植物混合后，有机溶剂溶解植物纤维中的杜仲胶丝，使用热水洗涤有机溶液可得到两相液体；水相带走植物组织杂质，在分离后的有机相中加入冰水可沉降杜仲橡胶。对比石油醚和氯仿作为有机溶剂在杜仲橡胶提取过程中的优缺点，认为氯仿更适合用于两相法提取杜仲橡胶。以两相分离法为基础设计了杜仲橡胶提取装置，并针对该装置使用中发现的问题对其进行了改进。 |
| 英文摘要: |
| 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. |
