Embodiment 1

[0078] Example 1 Preparation of effective components of Schisandra chinensis

[0079] Take 250g of Schisandra chinensis, 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. 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 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 Zorbax SB-C18; 21.2mm×250mm , the mobile phase is water A and acetonitrile B, and the gradient elution procedure is as follows:

[0080]

[0081] The flow rate is 10ml / min...

Abstract

The invention relates to an effective composition of fructus schizandrae. The preparation process comprises the following: step one: a mixture of acetic ether and ethanol is used as a solvent and carries out extraction on the fructus schizandrae; step two: an extraction solution is subjected to column chromatography to obtain an eluant; and step three: the eluant prepared through liquid phase chromatographic gradient elution uses water and acetonitrile as a mobile phase; and the eluant is collected for 44.0 to 48.0 minutes to obtain the effective composition. The invention also provides a method for preparing the effective composition and application thereof. The effective composition is first obtained through the method and is first applied to the drug effect screening of various tumor cell strains; and as the effective composition is precise and has definite content, a convenient preparation process and good activity, the effective composition is suitable to be developed into a novel antitumor Chinese medicine.

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 schisandra chinensis, 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 fr...
