Embodiment 1

[0090] Example 1 Preparation of Acanthopanax effective components

[0091] Take 250 g of Acanthopanax senticosus, crush it, add ethyl acetate and ethanol (1:1), heat to reflux for 1 hour, extract twice, and combine the filtrates to obtain the extract. The extract is concentrated into extract to obtain 26.7g, the extract and silica gel are mixed as a sample, and the normal phase silica gel column is used for separation, at first using sherwood oil and ethyl acetate (50: 1) as mobile phase to obtain eluent I, Then, chloroform and methanol (10:1) were used as the mobile phase to obtain the eluent II, which was concentrated and dried to obtain 4.0 g of the sample. The separation of the resulting sample was continued by preparative liquid chromatography. Separation conditions for preparative chromatography: the chromatographic column is an Agient preparative column (Zorbax SB-C 18 ; 21.2mm × 250mm), the mobile phase is water (A) and acetonitrile (B), and the gradient elution proc...

[0094] Example 2 Analysis of Acanthopanax effective components

[0095] Combined HPLC-ELSD analysis of the effective components of Acanthopanax senticosus of Example 1

[0096] Chromatographic conditions Chromatographic column Agilent Zorbax SB-C18 column (4.6mm × 150mm, 5 μm); using gradient elution, mobile phase A is 0.2% glacial acetic acid aqueous solution, mobile phase B is acetonitrile solution containing 0.2% glacial acetic acid; gradient elution The procedure is as follows: at 0 minutes, mobile phase A is 90% 0.2% glacial acetic acid aqueous solution, mobile phase B is 10% 0.2% glacial acetic acid in acetonitrile solution; at 10 minutes, mobile phase A is 50% 0.2% glacial acetic acid Aqueous solution, mobile phase B is 50% 0.2% glacial acetic acid acetonitrile solution; 30 minutes, mobile phase A is 5% 0.2% glacial acetic acid aqueous solution, mobile phase B is 95% 0.2% glacial acetic acid acetonitrile solution; 35 In minutes, the mobile phase A was 5% 0.2% glaci...

Embodiment 3

[0099] Example 3 Acanthopanax effective component preparation

[0100] Take the active component 1 or 2 of Acanthopanax in Example 1, mix 0.5g with 10.5g polyethylene glycol-6000 evenly, heat and melt, after the material is changed, move it to drip irrigation, and drop the medicine liquid to 6-8°C In liquid paraffin, degreasing, made 400 dropping pills.

Abstract

The present invention relates to an effective component of acanthopanax root and the preparation method and usage. For the effective component of acanthopanax root of the present invention, the preparation process includes the following steps: step 1: the mixture of ethyl acetate and ethanol is used as a solvent to extract acanthopanax root; step 2: the extract goes through column chromatography to obtain elution; step 3: the mobile phase of the eluent obtained from the preparation of liquid chromatogram gradient elution is water and acetonitrile, the eluent is collected for 23.9 to 29.1min or 33.4 to 39.5min so as to obtain the effective components.

Description

technical field [0001] The invention relates to a traditional Chinese medicine extract for treating tumor diseases, in particular to an effective component extracted from Acanthopanax acanthopanax, a preparation and a preparation method and use thereof. Background technique [0002] Tumor is a common and frequently-occurring disease, among which malignant tumor is the most serious disease that endangers human health. At present, the treatment of malignant tumors in the industry is mainly based on surgery, radiotherapy, and chemotherapy. However, many chemical anticancer drugs often involve normal cells when they act on target cells, causing serious side effects. The genotoxicity of botanical medicine is not obvious, and Chinese herbal medicine has unique advantages and broad application prospects in anti-cancer and anti-mutation, and Chinese medicine also plays a role that cannot be ignored in the adjuvant treatment of tumors. Paclitaxel is a typical natural compound obtain...
