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。该文以荆芥、青皮、香附、石菖蒲、佩兰、野菊花6味中药含油水体为试验体系,采用截留相对分子质量为7万的聚偏氟乙烯膜(PVDF-7万),在40℃,0.1 MPa,150 r·min-1下过膜,富集荆芥等6种挥发油,探索膜富集过程中的理化性质、原油和截留油指纹图谱相似度的共性规律,发现不同体系具有近似的规律,在富集过程至结束,荆芥等6种含油水体的pH逐渐降低至最低;电导率逐渐变大,后变小至为0;黏度逐渐增大至最大;表面张力逐渐减小至最小;浊度逐渐增大,后减小至最小;荆芥等含油水体的密度逐渐减小至最小,石菖蒲挥发油为重油,趋势相反;盐度均为0。到达终点,渗透液pH最大,密度最大(石菖蒲油水体系相反),其余均为最小。浓缩前后油的组成相似度均超过90%。该文结果为膜富集挥发油技术产业化推广提供了一定数据支持和理论依据。Membrane enrichment process of Chinese medicine volatile oil is green, practical and has a good application pros- pects. Schizonepetae Herba et al. six chinese medicine oily water were filtrated with polyvinylidene fluoride （PVDF） membrane with MWCO 70 000, at 40 ℃, 0. 1 MPa and 150 r · min^- 1, common laws of physicochemical property of six oily water and fingerprint simi- larity between original and preserved oil were studied during membrane enrichment. Results were as follows： pH was gradually reduced to the minimum ; conductivity firstly became larger, then smaller until 0 ; viscosity gradually increased to a maximum ; surface tension gradually decreased to a minimum; turbidity firstly gradually increased, then reduced to a minimum; density gradually decreased to a minimum, but the change trend was opposite for Acori Tatarinowii Rhizoma with heavy oil; salinity was 0. In the end, pH reached a maximum and density reached a maximum （ contrary for Acori Tatarinowii Rhizoma） and the other physicochemical property values reached a minimum for the last permeate. Fingerprint similarity between original and enriched volatile oil was above 90%. The above results provided data support and theoretical basis for the industrialization of membrane enrichment volatile oil technology.
