摘 要:目的:研究栀子水提液超滤膜过滤后含量和相对黏度的变化。方法:利用乌氏黏度计测量栀子水提液在不同密度、通过不同截留相对分子质量超滤膜处理后相对黏度的变化,考察超滤对去乙酰基车叶草苷酸甲酯、京尼平-1-β-D龙胆双糖苷、栀子苷3个成分的影响。结果:随着滤膜孔径的减小及药液相对密度的增加,各成分的损失率均有增大的趋势;超滤后栀子提取液的相对黏度明显降低,随着滤膜孔径及提取液相对密度的减小,超滤液的相对黏度也有所降低。结论:栀子水提液超滤后能显著降低相对黏度。Objective:To study on the change of content and intrinsic viscosity from water extract of Gardeniae Fructus by ultrafiltration.Method:Different relatively density was determined by Ubbelohde viscometer.Investigated the change of intrinsic viscosity by dealed with ultrafiltration of different retention molecular weight,then study on the effect of deacetyl-asperulosidic acid methyl ester,genipin-1-β-D-gentiobioside and geniposide by ultrafiltration.Result:With the pore size decreased and relative density increased,the loss rate of components have a tendency to increase;Relative viscosity of extract from Gardeniae Fructus reduced significantly after ultrafiltration,with the membrane pore size and extract the relative density decreased,the relative viscosity of ultrafiltrate also decreased.Conclusion:Viscosity of water extract from Gardeniae Fructus decreased significantly after ultrafiltration.
