Embodiment 1

[0077] Embodiment 1 Preparation of Imperatae effective components

[0078]The preparation method of the effective components of Imperatae Rhizome of the present invention comprises the following steps: adding ethyl acetate and ethanol (1:1) after pulverizing the Rhizoma Imperatae medicinal material, heating and refluxing for 1 hour, extracting twice, and combining the filtrates to obtain an extract; Concentrate into an extract, dissolve and load the sample with ethanol, and pass through the ODS-C18 column. First, use 30% EtOH (5BV; 1BV≈250ml) as the mobile phase to obtain eluent I, and then replace it with 95% EtOH (5BV) as the mobile phase phase, to obtain eluent II, and concentrate and dry the eluent II to obtain a sample; continue to separate the sample obtained by preparative liquid chromatography; separation conditions for preparative chromatography: the chromatographic column is a preparative column ZorbaxSB-C18; 21.2mm×250mm, The mobile phase is water A and acetonitrile...

Abstract

The invention relates to an effective component of cogongrass rhizome as well as a preparation method and an application thereof. The preparation process of the effective component comprises the following steps: (1) a mixture of ethyl acetate and ethanol is used as a solvent to extract the cogongrass rhizome; (2) an extracting solution is processed by chromatography through a chromatographic column to obtain an eluent; (3) the eluent is eluted by prepared liquid chromatogram gradient and is collected for 56.0-60.0 minutes to obtain the effective component by taking water and acetonitrile as flow phases.

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 the rhizome of Imperata coronata, a preparation, a preparation method and application 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 c...
