Embodiment 1

[0141] Embodiment 1 Preparation of effective components of Prunella vulgaris

[0142] Take 250 g of Prunella vulgaris, 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 16.6g, 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 5.0 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...

Embodiment 2

[0145] Example 2 HPLC-ELSD Analysis of the Effective Components of Prunella vulgaris

[0146] 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% glacial acetic acid in water, and the mobile phase B was 95% 0.2% glacial acetic acid in ...

Embodiment 3

[0149] Example 3 Prunella vulgaris active ingredient preparation

[0150] Take the effective component 1 or component 2 of Prunella vulgaris of Example 1, mix 0.5g with 10.5g polyethylene glycol-6000 evenly, heat and melt, and move to the drip irrigation after the material is changed, and the medicine liquid is dripped to 6-8 ℃ in liquid paraffin, degreasing, made 400 dropping pills.

Abstract

The invention relates to an effective component of prunella vulgaris, a preparation method and application thereof; the preparation process of the effective component of prunella vulgaris in the invention includes the following steps: step 1, the mixture of ethyl acetate and ethanol is used as solvent for extracting prunella vulgaris; step 2, the extract is processed with chromatographic column chromatography to obtain eluate; step3, the eluate obtained by elution in the preparation of liquid phase chromatographic gradient is adopted; the mobile phase is water and acetonitrile, and the eluateof 24.0-28.0 min or 28.0-32.0 min is collected to obtain the effective component.

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 Prunella vulgaris, 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 obtained from ...
