Embodiment 1

[0128] The preparation of the effective component of embodiment 1 fragrant tea

[0129] Take 250 g of fragrant tea and vegetables, crush it, add ethyl acetate and ethanol (1:1), heat and reflux for 1 hour, extract twice, and combine the filtrates to obtain the extract. The extract is concentrated into extract to obtain 25.5g, 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 6.6 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 gra...

Embodiment 2

[0132] The analysis of the effective component of embodiment 2 fragrant tea dish

[0133] The HPLC-ELSD joint analysis of the effective components of the fragrant tea dish of embodiment 1

[0134] 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...

Embodiment 3

[0137] Embodiment 3 Fragrant tea active ingredient preparation

[0138] Take the active ingredient 1 or 2 of the fragrant tea dish in Example 1, mix 0.5g with 10.5g polyethylene glycol-6000 evenly, heat and melt, move the material to the drip irrigation after the material is made, 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 rabdosia and the preparation method and usage. For the effective component of rabdosia 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 rabdosia; step 2: the extract goes through column chromatography to obtain the eluent; 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 20.0 to 24.0min or 24.0 to 28.0min so as 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 fragrant tea leaves, 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 fro...
