Embodiment 1

[0025] Example 1: Preparation of Galla gall anti-tumor effective component extract

[0026] The medicinal material Galla chinensis is dried and pulverized. Take 400g of medicinal powder, add 250ml of petroleum ether, stir evenly for 5min, let it stand for 1h, filter to remove petroleum ether, repeat 3 times, take out the medicine and dry it. Divide the above sample into 4 parts, add 1L of water, reflux extraction for 2 hours, repeat the extraction of medicinal dregs 4 times, and collect the filtrate. Concentrate the filtrate to about 200ml with a rotary evaporator, add 450ml of 95% ethanol, stir, and let stand overnight. Filter, take the filtrate, and use a rotary evaporator to evaporate the ethanol until there is no ethanol smell to obtain 200ml of crude extract. The crude extract was extracted four times with ether (250 ml of ether each time), the ether layers were combined, and evaporated with a rotary evaporator until there was no ether smell, and a brown extract was o...

[0028] Example 2: Preparation of Galla gall anti-tumor effective component extract

[0029] The medicinal material Galla chinensis is dried and pulverized. Take 400g of medicinal powder, add 350ml of petroleum ether, let it stand overnight, filter to remove petroleum ether, take out the medicine and dry it in the air. Divide the above sample into 4 parts, add 1 L of water, reflux extraction for 3 hours, repeat the extraction of medicinal dregs twice, and collect the filtrate. Concentrate the filtrate to about 300ml with a rotary evaporator, add 600ml of 95% ethanol, stir, and let stand overnight. Filter, take the filtrate, and use a rotary evaporator to evaporate the ethanol until there is no ethanol smell to obtain 300ml of crude extract. The crude extract was extracted three times with the same volume of ether, the ether layers were combined, and evaporated with a rotary evaporator until there was no ether smell, and a brown extract was obtained, which was the antitumor ...

Embodiment 3

[0031] Example 3: Preparation of Solid Galla Galla Antitumor Active Component Extract

[0032] The medicinal material Galla chinensis is dried and pulverized. Take 80g of medicinal powder, add 80ml of petroleum ether, stir evenly, let stand overnight, filter to remove petroleum ether, take out the medicine and dry it. The above sample was added to 600ml of water, refluxed for 2 hours, and the dregs were extracted twice, and the filtrate was collected. Concentrate the filtrate to about 80ml with a rotary evaporator, add 95% ethanol at a ratio of 95% ethanol:medicine solution 6:1, stir for 10 minutes, let stand overnight, filter, take the filtrate, and steam the ethanol out with a rotary evaporator. Until there is no ethanol smell, 80ml of crude extract is obtained. Extract the crude extract with 100ml of ether, extract twice, about 10 min each time, take the ether layers and combine them, evaporate them with a rotary evaporator until there is no ether smell, and dry them to o...

Abstract

The invention provides an extract of effective components of antineoplastic gallnut. The extract is prepared from the following steps in sequence: drying the gallnut: crushing the dried gallnut; adding petroleum ether to remove the oil; drying in the air; carrying out water extraction and alcohol precipitation; evaporating to remove ethanol from the filtrate; extracting by diethyl ether; and concentrating the extractive liquid under diethyl ether, thus obtaining the extract of the effective components of antineoplastic gallnut. As the study shown, the extract of the effective components has the activity of inhibiting the growth of U251 (glioma cells) outside the body, so that the extract can be applied to preparation and development of antineoplastic medicines. The invention also discloses a preparation method of the extract.

Description

technical field [0001] The present invention relates to the extract of the anti-tumor effective part of Galla chinensis, the pharmaceutical composition containing it, its preparation method and application. Background technique [0002] Tumor is one of the most serious diseases that endanger human health in the world today. At present, tumor treatment includes surgery, radiotherapy, chemotherapy, intervention and other means, but the mortality rate is still high, and has now risen to the first [see: Xiao Zhenyu, He Shaozhong, Peng Weiwei. 2011, 22(23): 2204-2206]. Experts and scholars from all over the world are actively researching methods and drugs for treating tumors. Traditional Chinese medicine has a long history of treating difficult diseases such as cancer, and the active ingredients in medicinal plants can exert their biological effects through multiple channels and multiple targets. In particular, plant-derived drugs and their derivatives, such as vincristine, hyd...
