摘要
目的对无机陶瓷膜微滤技术精制何首乌水提液的效果进行初步评价。方法用孔径为0.2μm的无机陶瓷膜对何首乌水提液进行微滤,对提取液微滤前后在性状、总固体、二苯乙烯苷含量、膜通量等方面的变化进行对比分析。结果何首乌水提液微滤前为浑浊溶液,微滤后为澄清溶液,透过液固体去除率为67.9%、二苯乙烯苷含量是水提取液中的2.04倍,膜通量的衰减具有一定的规律性。结论无机陶瓷膜微滤技术对何首乌提取液有较好的精制效果。
Objective To evaluate the effect of microfiltration on the extract of polygonum multiflorum by inorganic ceramic membrane. Methods The extract of polygonum multiflorum was processed by inorganic ceramic membrane. The character, whole solid, content of stilbene glycoside and the flux of membrane were examined. Results The extract of polygonum multiflorum became clear after microfiltration. The decreasing rate of the whole solid was 67.9%, and the content of stilbene glycoside was 2.04 times that of the extract of polygonum multiflorum. The decay of flux of membrane had a certain regularity. Conclusion The microfiltration of inorganic ceramic membrane has good effect on the extract of polygonum multiflorum.
