水提紫甘薯色素废渣促进小鼠通便作用的研究

Study on the Effect of Catharsis Function of Waste Residue from Extracting Pigment of Ipamoea batatas L.in Mice

本研究评价水提紫甘薯色素废渣通便保健功能,以2.5、5、10 g/kg.bw.d受试物经口给予小鼠10 d,结果表明:模型组与空白组相比,墨汁推进率、首粒排黑便时间、6 h排黑便粒数及黑便重量具有统计学差异(P<0.01),表明模型建立成功;高剂量组墨汁推进率高于模型组,墨汁推进率增加10.3%,而低、中剂量组墨汁推进率有增加的趋势。各剂量组首粒排黑便时间有降低趋势。中、高剂量组黑便粒数高于模型组,6 h内排黑便粒数分别增加5.9(63.4%)、4.4(47.3%)。各剂量组黑便重量和每粒黑便平均重量高于模型组,6 h内排黑便重量分别增加120.5 mg(89.4%)、226.4 mg(168.0%)、233.8 mg(173.5%),各剂量组每粒黑便平均重量较模型组分别增加4.9 mg(32.9%)、7.3 mg(49.0%)、12.3 mg(82.6%),因此水提紫甘薯色素废渣具有一定的通便功能。

In order to evaluate the Catharsis Function of remaining waste residue of purple sweet potato, the mice have been given respectively 2.5, 5 and 10 g/kg.bw.d from mouth filling in stomach for 10 days. The results showed that there were significant differences between model group and control group on following items： ink motional rate, the time of first defecate, the quantity and weight of 6 hours dejecta（P〈0.01）. These results proved the success of building model. The high dose level of ink motional rate of control group was higher than model group. The ink motional rate increased by 10.3 percent, the increase trend was found in low group and moderate group and the decrease trend of the time of first defecate was found in each dose level. The quantities of dejecta of high dose group and moderate dose group were higher than model group. The quantities of 6 hours dejecta of high dose group and moderate dose group respectively increased by 5.9 （63.4 percent） and 4.4 （47.3 percent）. The weights and the average weights of each dejecta of high does group, moderate group and low group were higher than model group. The weight of 6 hours dejecta respectively increased by 120.5 mg （89.4 percent）,226.4 mg （168.0 percent） and 233.8 mg （173.5 percent）. The average weights of each dejecta of high does group, moderate group and low group respectively increased by 4.9 mg （32.9 percent）, 7.3 mg （49.0 percent） and 12.3mg （82.6 percent） compared to the model group, The catharsis function of remaining waste residue of purple sweet potato was proved.
