| 摘 要： | 目的]揭示中草药提取过程对提取残渣常规营养成分的影响规律,为中草药提取残渣营养价值评定提供基础资料。方法]以黄芪、麦芽和甘草为研究对象,对其分别进行水煮和提取处理,分别测定3种原料经不同处理后的质量损失率及其处理后产物的常规营养成分。结果]黄芪、麦芽和甘草经水煮和提取处理的质量损失率分别为13.38%、11.62%、5.04%和37.34%、29.13%、21.36%;经2种处理后,产物CP含量呈无规律变化,其变化幅度均相对较小,Ash含量呈一定程度降低,CF、NDF、ADF含量均大幅度升高（P〈0.05）,NFE含量均不同程度降低。结论]中草药提取处理的质量损失率远大于水煮处理;在无特殊需求时,不必对中草药进行水煮处理;从潜在营养价值的角度来看,麦芽以及黄芪和甘草提取残渣分别具有作为优质精饲料和粗饲料的营养潜力。

Effects of Water Boiling and Extracting Treatments on Normal Nutritional Components of Chinese Herbal Medicine |
| |
| Abstract: | Objective]To uncover the influence of extraction process on the normal nutritional components of extracting residues from Chinese herbal medicine, and to provide basic data for the nutritional value evaluation of Chinese herbal medicine extracting residues. Methods] Three kinds of Chinese herbal medicine, including astragalus, malt and licorice were used as materials in this study, and they were subjected to the treatment of water boiling and extracting, respectively. The quality loss rate and the normal nutritional components content of the post-treatment products of three medicines were determined. Results]The quality loss rate of astragalus, malt and licorice after the treatment of water boiling and extracting was 13.38%, 11.62%, 5.04% and37.34%, 29.13%, 21.36%, respectively; the CP content of the product showed irregular changes after the two treatments and the changing amplitude of the three medicines was all relatively small; Ash content exhibited a decreasing trend to some extent; the contents of CF, NDF and ADF was increased significantly（P〈 0.05）; the NFE content was decreased in different degrees.Conclusion]The quality loss rate of Chinese herbal medicine after extracting treatment is largely higher than that after water boiling treatment; Chinese herbal medicine is not necessary to be subjected to water boiling treatment unless there are special requirements; from the perspective of potential nutritional value, the extracting resides of malt and astragalus has the nutritional potential as high-quality refined feed, and those of licorice has the nutritional potential as roughage feed. |
