Optimization of Extraction Process for Oil and Gutta-percha from Key Fruit of Eucommia uimoides Oliv.
摘要
Abstract
[Objective] To obtain high - quality long silk gutta - pereha and seed oil from key fruit of Eucommia ulmoides Oliv.. [ Method] Treated with low concentration alkali and cellulase, the key fruits of Eucommia ulmoides Oliv. Were extracted with petroleum ether, petroleum e-ther combing with ultrasonic and conventional extracting method, respectively, optimizing the extracting process. [ Result] The Optimal pretreat-ment conditions for Key fruits of Eucommia ulmoides Oliv. Were: using 0.50% NaOH at 70 ℃ to remove cuticle and treating with cellulose with pH of 4 at 40℃. In comparison with conventional extracting method, extracted at room temperature and high temperature individually, Eucommia ulmoides Oliv. Increased 23.00% in oil yield and 58.00% in gutta - percha yield. In addition, extracted with ultrasonic extraction, it increased 42.00% in oil yield and 76.00% in gutta - pereha yield, while reduced 90.00% in extracting duration. [ Conclusion ] The suitable extracting process of seed oil and gutta - pereha from key fruit of Eucommia ulmoides Oliv. Could be selected in terms of actual conditions, which provided scientific basis for producing high-quality and high yield of seed oil and gutta - pereha from key fruit of Eucommia ulmoides Oliv..关键词
