A large number of herb materials contain essential oils with extensive bioactivities. In this work, an integrated simultaneous distillation-extraction (ISDE) apparatus was developed. To demonstrate its feasibility, the performance of ISDE was evaluated for the extraction of essential oil from Flos Magnoliae and compared with conventional techniques including steam distillation (SD) and simultaneous distillation-extraction (SDE). According to the product yield, the time consumed and the composition of oil, the essential oils isolated by ISDE were better than that obtained by SD and similar to those obtained by SDE. ISDE was also better than SDE due to its simple operation and lower consumption of energy and organic solvent.
大量草药原料含有具有广泛生物活性的精油。在本研究中，开发了一种集成同时蒸馏萃取（ISDE）装置。为证明其可行性，对ISDE从辛夷中提取精油的性能进行了评估，并与包括水蒸气蒸馏（SD）和同时蒸馏萃取（SDE）在内的传统技术进行了比较。根据产物收率、耗时和油的组成，ISDE分离得到的精油优于SD法得到的精油，与SDE法得到的精油相似。ISDE还因其操作简单、能量和有机溶剂消耗较低而优于SDE。
