摘要： 目的比较传统水提醇沉工艺和超频震动薄膜过滤技术分离浓缩小叶榕叶提取液的效果。方法考察、分析不同孔径A，B，C，D膜的过滤稳定性、通量、有效成分收率及除杂，选择合适的膜及运行参数。结果B孔径膜最适合小叶榕叶有效成分的分离，配合D孔径膜，可使分离浓缩连续进行，工序少，周期短，效率高，成本低，能耗低，安全指数高，膜不易堵塞，膜的保存和再生工序简单。结论此法用于小叶榕叶提取液生产，可替代传统的醇沉分离和加热浓缩中总黄酮的分离、浓缩工艺。

Abstract：Objective To compare the effect of routine water extraction and alcohol precipitation method with vibratory shear enhanced membrane filtration from separating and concentrating aqueous extractives of Ficus microcarpa L.f.Methods Membranes of four different pore size were equipped for the filtration system to investigate the filtration flux, stability, yield of active ingredients and foreign matter removal ability.ResultsMembrane B showed the best performance in the separation of active ingredients of F. Microcarpace while membrane D could concentrate active ingredients. Vibratory shear enhanced membrane filtration made the separation and concentration consecutively done with a few processes, short cycle time, high efficiency, low cost, low energy expenditure and high reliable index.Conclusion Vibratory shear enhanced membrane filtration is a better technology than routine water extraction and alcohol precipitation method for the separation and concentration of aqueous extractives of Ficus microcarpa L.f.
Key words：vibratory shear enhanced membrane filtration; water extraction and alcohol precipitation; Ficus microcarpa L.f.
中药成分复杂，提取分离时要保留有效成分并尽可能地去除鞣质、蛋白质、淀粉、树脂等大分子杂质。蒸馏、醇沉等传统中药提取方法不易除尽杂质，有效成分损失大，而且消耗大量有机溶剂。膜分离技术可有效地去除杂质、保留有效成分，且对环境无污染。近年膜分离技术广泛用于制备中药注射剂、口服液、浸膏，取得了良好的效果[1] ，但目前主要是静态过滤，工艺过程中易堵塞膜孔，使通量锐减，缩短了膜的使用寿命 [2]。
本实验将超频震动膜过滤技术直接用于中药水提液的分离和浓缩 ......
