Study On The Extraction Of Pectin From Dried Beet Pellet And Effect Of Beet Pectin On Mice Suffering From Hyperlipemia

Objectives:It was studied to extract pectin from dried beet pellet and effect of beet pectin on hyperlipemia mice .Methods: Acid extraction and ethanol sedimentary method were used to extract pectin from dried beet pellet. Orthogonal design was used to optimize the better acid extraction conditions. 84 health mice, male, were divided into six groups on the base of the weight , 14 mice each group. The experimental control group was administrated with high cholesterol,while the groups of Oleanolic acid(OA) and Pectin were administrated with their own sample except high cholesterol .One week later , the contents of serum total cholesterol (TC), triglycerides(TG) and HDL were measured ;the livers were fixation with formaline. Results:The optimum acid extraction from dried beet pellet was 20 times volumn 0. 1M HC1,80℃ for 4 hours. The optimum ethanol sedimentary conditions : density of the liquor was 0.972, the volumn of 95% ethanol was 4 times. Beet Pectin showed the actions of decreasing the levels of TC and TG. OA also decreased the levels of TC and TG. Conclusions: Pectin can be extracted by acid extraction and ethanol sedimentary method. Beet Pectin is an effective agent for hyperlipemia.
