Embodiment 1

[0151] The preparation of the effective component of embodiment 1 Fangji

[0152] Take 250 g of Antichristia chinensis medicinal material, grind it, add ethyl acetate and ethanol (1:1), heat to reflux for 1 hour, extract twice, and combine the filtrates to obtain the extract. Concentrate the extract into extract to obtain 8.6g, dissolve and load the sample with ethanol, and pass through the ODS-C18 column. First, use 1250ml of 30% ethanol as the mobile phase to obtain the eluate, discard it, and then replace it with 1250ml of 95% ethanol as the mobile phase. phase, to obtain the eluent II, and the eluent II was concentrated and dried to obtain a sample; the sample obtained by further separation by preparative liquid chromatography; the separation conditions of preparative chromatography: the chromatographic column is a preparative column Zorbax SB-C18; 21.2mm×250mm , the mobile phase is water A and acetonitrile B, and the gradient elution procedure is as follows:

Abstract

The invention relates to an effective component of radix stephaniae tetrandrae, a preparation method and application thereof; the preparation process of the effective component of radix stephaniae tetrandrae in the invention includes the following steps: step 1, the mixture of ethyl acetate and ethanol is used as solvent for extracting radix stephaniae tetrandrae; 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 eluate of 8.0-16.0 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 Fangji, 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 plants with...
