Embodiment 1

[0062] Example 1 Preparation of effective components of Schisandra chinensis

[0063] 250g schisandra chinensis is crushed, add 8 times the amount of ethyl acetate:ethanol=1:1, heat and reflux for 1 hour, extract twice, add 8 times the amount of 70% ethanol to the dregs, heat and reflux for 1 hour, extract twice, and combine the filtrates to obtain the extraction After concentrating the extract, dissolve the sample with 5% methanol, and pass it through the ODS-C18 column. First, use 5% ethanol as the mobile phase, and then replace it with 50% ethanol as the mobile phase to obtain the eluent, which is used to prepare the liquid phase Chromatography continues to separate the eluent, separation conditions: the chromatographic column is an Agilent 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 active component of schisandra fruit, and a preparation method and the application thereof. The preparation process comprises the following steps: step 1, the mixture of ethyl acetate and ethanol is taken as a solvent for extracting the schisandra fruit; step 2, the eluent is obtained from an extracting solution through chromatographic column chromatography; and step 3, the eluent is prepared by liquid chromatography gradient elution, the mobile phase includes water and acetonitrile, and the active component is obtained after the eluent is collected for 24.0-28.0 min, 28.0-32.0 min, 32.0-36.0 min, 48.0-52.0 min, 52.0-56.0 min and 60.0 -64.0 min.

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...
