Embodiment 1

[0041] Preparation of rushes ethanol extract and water extract: dry rushes material, crushed, 5-10 times the amount of 95% ethanol or water-cooled soaking extraction twice, each time 24h, combined extracts, filtered, concentrated under reduced pressure to obtain thick soaking paste, put it in an oven and dry it at 65°C to get it.

Embodiment 2

[0043] Preparation of rushes petroleum ether and ethyl acetate parts: dry rushes material, crushed, 5-10 times the amount of 95% ethanol for cold extraction twice, each time for 24 hours, combined extracts, filtered, concentrated under reduced pressure to obtain a thick extract , add water to suspend, sequentially extract with petroleum ether (60-90°C) and ethyl acetate. The petroleum ether layer and the ethyl acetate layer extract are recovered respectively to obtain the petroleum ether extract and the ethyl acetate extract. The yields are about 1% and 5%, respectively.

Abstract

The invention discloses application of Juncus effuses L. extract in preparing an anti-tumor or angiogenesis-inhibiting medicament. The invention discloses that the Juncus effuses L. extract has activities of inhibiting tumor and tumor angiogenesis for the first time, and the Juncus effuses L. extract can be used for treating or preventing diseases related to tumor and tumor angiogenesis, and also can be used in treatment for chemotherapy and / or adjuvant chemotherapy of tumor. The invention takes angiogenesis as the target spot for treating diseases, studies and explains the pharmaceutical curative effects and mechanism of the Juncus effuses L. extract, and provides a scientific basis and important information for the development of new use of the Juncus effuses L. extract and discovery of new target spots of drug action. The Juncus effuses L. extract can be applied to medicaments, health products and / or cosmetics and the like.

Description

technical field [0001] The invention belongs to the technical field of traditional Chinese medicine. It specifically relates to the application of a rush extract in the preparation of anti-tumor or angiogenesis-inhibiting drugs, health food or cosmetics. Background technique [0002] Tumor is a disease that seriously threatens human life and health. Statistics from the Ministry of Health show that the number of malignant tumor patients in China has reached 115-1.27‰, and the number of deaths due to malignant tumors ranks second among all causes of death. Although great progress has been made in the treatment of malignant tumors in the past half century, there is still a lack of ideal therapeutic drugs to meet clinical needs, and malignant tumors are still regarded as refractory diseases. Finding safe and effective anti-tumor drugs is still a hot and difficult point in the medical circles of various countries. [0003] Tumor growth and metastasis rely on new blood vessels t...
