Abstract
The invention relates to a natural pharmaceutical composition, preparation method thereof and the usage in preparing an attenuated synergistic medicament in cancer chemotherapy, wherein the natural pharmaceutical composition consists of decoction condensed extract product of dried orange peel and yam, nobiletin, ethanol extract product of yam and yam polysaccharide in a proportion of (4-5):(2-8):(1-3):(5-9). The composition has good curative effect to cancer chemotherapy related diarrhoea and increases effect to cancer chemotherapy.
Description
Technical field
The present invention relates to a kind of natural drug composition, relate more specifically to a kind of natural drug composition of being made up of Pericarpium Citri Reticulatae Rhizoma Dioscoreae water boiling concentration extract, Nobiletin, Rhizoma Dioscoreae ethanol extraction and Chinese yam polysaccharide, the preparation method of this natural drug composition and this natural drug composition are being used for preparing the purposes that reduces cancer chemotherapy dependency diarrhoea and treatment of cancer is played the medicine of potentiation.
Background technology
Malignant tumor is current harm humans existence, one of healthy principal disease, and its treatment means comprises operation, chemotherapy, radiotherapy, Chinese medicine, and the effect of chemotherapeutic treatment tumor is particularly outstanding.Chemotherapeutic no matter singly with or unite with toxicity such as all can cause that the patient suffers from diarrhoea, diarrhoea makes the chemotherapy dependency suffer from diarrhoea again behind the chemotherapy of tumors.Emerging and applying along with chemotherapeutics such as 5-fluorouracil, taxanes, hydroxy camptothecin, irinotecan, xeloda etc. in recent years, chemotherapy dependency diarrheal incidence rate improves year by year, and if do not carry out active treatment, easily cause patient's dehydration, malnutrition, serum electrolyte disorder, acid base imbalance etc., it is unfavorable greatly not only the rehabilitation of body to be brought, therefore also bring certain difficulty, to the important component part of chemotherapy dependency diarrheal effective treatment having become tumor patient wholistic therapy to CC.
Chemotherapy dependency diarrhoea is with regard to its clinical manifestation, surely belongs to the Chinese medicine category of " having loose bowels ", and Chinese medicine attracts people's attention for the research of having loose bowels, but still unmatchful anticancer disease chemotherapy has the Chinese patent medicine of alleviating diarrhoea and potentiation at present.Therefore, research and develop a kind of high-efficiency low-toxicity, cheap, the natural Chinese medicine that can be used for alleviating cancer chemotherapy dependency diarrhoea and playing the chemotherapeutic sensitivity effect that is easy to promote becomes clinical problem demanding prompt solution.
Pericarpium Citri Reticulatae, the mature peel for rutaceae orange (Citrus reticulata Blanco) and variety thereof is used for lack of appetite and vomiting.Rhizoma Dioscoreae is perennial voluble herb, Chinese medicine, vegetable dual-purpose, and motherland's medical science thinks that Rhizoma Dioscoreae has therapeutical effect to diarrhea due to hypofunction of the spleen.In recent years, Pericarpium Citri Reticulatae and Rhizoma Dioscoreae antitumaous effect are confirmed, especially Nobiletin and Chinese yam polysaccharide, the inventor is through the research and the experiment of each a large amount of formula proportion, obtained optimal drug ratio compositions of the present invention at last, be the compositions of novelty, and proved that it has fabulous curative effect and can and cancer chemotherapy be played potentiation cancer chemotherapy dependency diarrhoea, has finished the present invention thus.
Summary of the invention
A kind of natural drug composition provided by the invention, by Pericarpium Citri Reticulatae Rhizoma Dioscoreae water boiling concentration extract, Nobiletin, Rhizoma Dioscoreae ethanol extraction and Chinese yam polysaccharide by weight in 4-5: the ratio of 2-8: 1-3: 5-9 is formed.
