Embodiment 1

[0100] Embodiment 1 Preparation of Artemisia argyi effective components

[0101] Artemisia argyi leaves are pulverized, passed through a 20-mesh sieve, added 8 times the amount of ethyl acetate:ethanol=1:1, heated and refluxed for 1 hour, extracted 2 times, added 8 times the amount of 70% ethanol to the dregs, heated and refluxed for 1 hour, extracted 2 times Once, the filtrate was combined to obtain the extract, after the extract was concentrated, the sample was dissolved with 5% ethanol, and the ODS-C18 column was crossed. At first, 1250ml of 5% ethanol was used as the mobile phase, and then 1250ml of 50% ethanol was replaced as the mobile phase to obtain a wash. Remove the liquid, and continue to separate the eluent by preparative liquid chromatography. 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 effective component of artemisia leaves as well as a preparation method and an application thereof. The preparation process of the effective component of the artemisia leaves comprises the following steps: (1) a mixture of ethyl acetate and ethanol is used as a solvent to extract the artemisia leaves; (2) dregs of a decoction are extracted with the ethanol so as to obtain an extracting solution; (3) the extracting solution is processed by chromatography through a chromatographic column to obtain an eluent; (4) the eluent is eluted by prepared liquid chromatogram gradient and is collected for 28.0-32.0 minutes, 36.0-40.0 minutes, 48.0-52.0 minutes, 52.0-56.0 minutes and 52.0-60.0 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 leaves of mugwort, 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 ...
