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 comprises the following steps: (1 )a mixture of ethyl acetate and ethanol is used as a solvent to extract the artemisia leaves; (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 4.0-8.0 minutes, 8.0-10.0 minutes, 16.0-20.0 minutes, 20.0-24.0 minutes, 24.0-28.0 minutes, 28.0-32.0 minutes and 36.0-40.0 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 fro...
