摘　　要：中药挥发油膜富集过程绿色环保,切实可行,具有良好的应用前景。该文以丁香、荆芥、佩兰、石菖蒲、辛夷、野菊花、香附、青皮8种含油水体为试验体系,在统一条件[截留相对分子质量为14万的聚偏氟乙烯膜(PVDF-14W),温度40℃,压力0.1 MPa,膜面速度150 r·min-1]下对上述8种含油水体进行过膜,探索中药含油水体的溶液环境对膜时通量和收油率的影响规律。结果表明,pH较小的体系通量相对较低,对挥发油截油率未表现出明显趋势;表面张力与纯水的表面张力相差越大,其截油率越小;电导率对膜富集过程未有显著影响规律;浊度大的体系通量低,对挥发油截油率未表现出明显趋势;重油的通量低于轻油的,而截油率略高于轻油;黏度较大的体系通量要比黏度较小的低,除辛夷挥发油外,挥发油的截油率明显高于黏度大的体系。试验结果为膜富集挥发油技术产业化推广提供一定数据支持和理论依据。The membrane enrichment process of traditional Chinese medicine volatile oil is environmental friendly and practi- cal, with a good application prospect. In this article, oil-bearing solutions of eight traditional Chinese medicines, namely Caryophylli Flos, Schizonepetae Herba, Eupatorii Herb, Acori Talarinowii Rhizoma, Magnoliae Flos, Chrysanthemum indicum, Cyperi Rhizoma and Citri Reticulatae Pericarpium Viride, were taken as the experimental system. Under unified conditions （membrane： PVDF-14W, temperature： 40 ~C, pressure： 0. 1 MPa, membrane surface speed： 150 r ~ min-t ）, trans-membrane was conducted for above eight oil-bearing solutions to explore the effect of their oil-bearing solution environment on system flux and oil recovery rate. The results showed that systems with smaller pH had a lower flux, without significant effect on oil recovery rate. Greater differences between the surface tension of solutions and that of pure water contributed to a lower oil recovery rate. The conductivity had no notable effect on membrane enrichment process. Systems with high turbidity had a lower flux, without remarkable effect on oil recovery rat. Heavy oils showed lower flux than light ones, but with a slightly higher oil recovery rat. Systems with higher viscosity had a lower flux than those with lower viscosity. Except for Magnoliae Flos volatile oil, all of the remaining volatile oils showed a much higher oil recovery rat than systems with high viscosity. The above results could provide data support and theoretical basis for the industrialization of membrane en- richment volatile oil technology.
