Embodiment 1
[0045] Example 1 The preparation of the active part of the root of Yu grape
[0046] (1) Heat and reflux 1Kg of dried japonica root with 12L of 95% ethanol to extract twice, 1 hour each time, combine the extracts, concentrate and dry them, and obtain 50 g of jasmine root ethanol extract;
[0047] (2) A silica gel column with 200-300 meshes and 1000 g of silica gel is installed on the obtained grape root alcohol extract, and the column volume (the volume occupied by the silica gel filler) is about 2.5 liters;
[0048] (3) Use 12.5 liters of cyclohexane / ethyl acetate (volume ratio 93:7) to remove impurities;
[0049] (4) Use 12.5 liters of cyclohexane / ethyl acetate (volume ratio 86:14) for elution, collect the eluate, concentrate and dry to obtain the active part of the root of Grape japonica.

Abstract
The invention relates to the field of an application of an active part of a traditional Chinese medicine, and in particular relates to a method for preparing a delavay ampelopsis root active part by utilizing a silica gel chromatographic technique. The preparation method for the active part comprises the following steps: (1) extracting the delavay ampelopsis root with alcohol, to obtain a delavay ampelopsis root alcohol extract; (2) feeding the obtained delavay ampelopsis root alcohol extract on a silica gel column, removing impurities with an eluting agent A; and (3) eluting by an eluting agent B, collecting eluted parts, concentrating and drying, so as to obtain the delavay ampelopsis root active part. The delavay ampelopsis root active part prepared by using the preparation method provided by the invention has an excellent effect in dispelling the effects of the alcohol, not only is a novel application of the delavay ampelopsis root discovered, but also the alcohol effect dispelling active part is discovered from the delavay ampelopsis root by utilizing the traditional Chinese medicine together with the modern measures, the prepared delavay ampelopsis root active part can be used for producing novel medicine for dispelling the effects of the alcohol. In addition, the preparation method for the delavay ampelopsis root active part is simple and is suitable for industrialized production.
Description
technical field [0001] The invention relates to the technical field of extracts of traditional Chinese medicines, in particular to a method for preparing the active part of japonica root by using silica gelchromatography technology. Background technique [0002] Wine culture has a history of thousands of years in our country, and drinking is inseparable from most social activities and daily life. However, excessive drinking can cause headaches, dizziness, nausea and vomiting, memory loss, and even blurring. Excessive drinking will also bring adverse effects to the family and society, such as destroying public property after drinking, disturbing social order, and causing serious traffic accidents due to drunk driving.
