目的:研究不同条件下栀子水提液特性黏度在果胶酶处理后的变化。方法:利用乌氏黏度计测量栀子水提液在不同密度、果胶酶用量、温度、时间等条件处理后特性黏度的变化,同时测定了去乙酰基车叶草苷酸甲酯、京尼平-β-D-龙胆双糖苷、栀子苷3个成分的变化。结果与结论:溶液相对密度、加酶量能显著影响栀子水提液酶处理的特性黏度,同时果胶酶也能影响京尼平-β-D-龙胆双糖苷与栀子苷的含量。
Objective:This paper describes the intrinsic viscosity difference of Gardenia extract treated with pectinase.Method:The intrinsic viscosity analysis was carried out on an Ubbelohde viscometer to determine the change after treated with different relatively density,amount of pectinase,time,temperature,etc.And the changes of geniposide,genipin-1-β-D-gentiobioside and deacetyl-asperulosidic acid methyl ester were also detremined respectively.Conclusion:Pectinase brought about the change of content of geniposide,genipin-1-β-D-gentiobioside and deacetyl-asperulosidic acid methyl ester,the maximum change rate of them was genipin-1-β-D-gentiobioside.
