【摘要】 目的 确定杜仲叶、皮、壳提取杜仲胶的优化生产工艺。方法 采用杜仲胶纯度测定法测定优化对比实验。结果 杜仲叶、皮、壳提取杜仲胶优化生产工艺使杜仲胶得率得到提高，这使得其在生产过程中产生的非必须消耗与制作时间都有了一定的改善。结论 杜仲叶、皮、壳采用优化的亚临界生产工艺技术，这在保证质量的前提下减少了企业的成本投入。更多还原

【Abstract】 To determine t optimal production process for extracting gutta-percha from the leaves, barks and seed shells of Eucommia ulmoides,the optimized comparison experiment was conducted by the gutta-percha purity determination method.The optimized production process for extracting gutta-percha from leaves, barks and seed shells of eucommia ulmoides could increase the yield of gutta-percha, the unnecessary consumption and production time during the production process were improved. The subcritical production technology was used to extract gutta-percha from leaves, barks, and seed shells of Eucommia ulmoides to reduce the cost without sacrificing the quality.更多还原
