Problems solved by technology

In the invention patent "Extraction of Active Components of Xiaoaiping and Preparation of Dosage Forms" (Application No.: 92102027.9), it is believed that the polysaccharides extracted from Aegypti aegypti are its anti-tumor active components, and there are no reports of other active components.
Therefore, it is very unfavorable for quality control and clinical drug safety
[0005] In addition, traditional Chinese medicine extracts often have complex components. Therefore, further research on the active ingredients with anti-tumor activity in S. sinensis can not only reduce the waste of plant resources, but also provide industrial extraction and separation methods for finding a single compound with stronger anti-tumor activity. is very necessary

Embodiment 1

[0071] Preparation of glucoside B

[0072]Take 1000g of the dried cane of S. chinensis, add water to cover the medicinal materials, decoct three times for 1 hour each, combine the decoctions, filter, concentrate the filtrate to 400ml, and let it cool to obtain the extract of S. Dissolve the ointment in 500ml of water, add 500ml of absolute ethanol, shake to precipitate with alcohol, filter, extract the filtrate with chloroform, collect the orange-red clear liquid in the lower layer, and repeatedly extract until the lower layer is colorless. After combining the chloroform extracts, add about 100ml of anhydrous ether , shake the ether to sink, filter, and drain the filtrate. After the extract was dissolved in chloroform, it was separated through a silica gel column, washed with chloroform, and the eluate was collected, and the collected liquid was monitored by thin-layer chromatography. The developing solvent was n-butanol: ethyl acetate: water = 4: 1: 15, and the thin layers we...

[0074] Preparation of glucoside B

[0075] Take 1000g of the dried cane of S. chinensis, add water to cover the medicinal materials, decoct three times for 1 hour each, combine the decoctions, filter, concentrate the filtrate to 400ml, and let it cool to obtain the extract of S. Dissolve the ointment in 500ml of water, add 1000ml of absolute ethanol, shake to precipitate with alcohol, filter, extract the filtrate with chloroform, collect the orange-red clear liquid in the lower layer, and repeatedly extract until the lower layer is colorless. After combining the chloroform extracts, add about 200ml of anhydrous ether , shake the ether to sink, filter, and drain the filtrate. After the extract was dissolved in chloroform, it was separated through a silica gel column, rinsed with chloroform, collected the eluent, and monitored by thin-layer chromatography of the collected liquid. The developing solvent was n-butanol: ethyl acetate: water = 4:1:15, and the thin layers were combin...

[0077] Preparation of glucoside B

[0078] Take 1000g of the dried cane of S. chinensis, add water to cover the medicinal materials, decoct three times for 1 hour each, combine the decoctions, filter, concentrate the filtrate to 400ml, and let it cool to obtain the extract of S. Dissolve the ointment in 500ml of water, add 750ml of absolute ethanol, shake for alcohol precipitation, filter, and extract the filtrate with chloroform, collect the orange-red clear liquid in the lower layer, and repeatedly extract until the lower layer is colorless. After combining the chloroform extracts, add about 150ml of anhydrous ether , shake the ether to sink, filter, and drain the filtrate. After the extract was dissolved in chloroform, it was separated through a silica gel column, washed with chloroform, and the eluate was collected, and the collected liquid was monitored by thin-layer chromatography. The developing solvent was n-butanol: ethyl acetate: water = 4: 1: 15, and the thin layers...

Abstract

The invention relates to an application of a compound marsdenia tenacissima glycoside B which is extracted and separated from natural plant marsdenia tenacissima in the preparation of a drug for remedying tumour diseases including various malignant tumour diseases, such as ovary cancer, stomach cancer, liver cancer, leucocythemia, lung cancer, oral epidermoid carcinoma, rectal adenocarcinoma, breast cancer, malignant melanocarcinoma, colon adenocarcinoma, nasopharyngeal carcinoma, prostate cancer, etc. The invention also relates to a preparation technology of the marsdenia tenacissima glycoside B. After using water extraction and alcohol sedimentation, the invention uses an innovative chloroform extraction and aether sedimentation technology by chloroform extraction and also creatively adding aether, thereby reducing the content of impurity in extract obviously, and the marsdenia tenacissima glycoside B with high purity can be obtained just by silica gel column separation at a time. The method has high yield and simple operation, does not require a preparation type precision instrument of high performance liquid phase and other similar instruments and is closer to the requirement of the industrialized production.

Description

technical field [0001] The present invention relates to the application of the compound genus glucoside B extracted and separated from the natural plant Aegyptifolia in the preparation of medicines for treating tumor diseases, and an industrialized extraction and separation method thereof. Background technique [0002] Mersolenia tenocissima (Roxb) is a plant of the genus Milkweed in the family Romoaceae, and its scientific name is Mersolenia tenocissima (Roxb), also known as Tongguansan, Tongguanteng, Dakuteng, Xiamiliteng, etc. It is used as a medicine for treating bronchitis and anti-tumor in Yunnan plant. Since 1970, the 33970 troops of the People's Liberation Army have used the decoction of Wuguteng to treat various malignant tumors and achieved good results. [0003] However, there are few research reports on the anti-tumor active ingredients of Acacia sinensis at home and abroad. In the invention patent "Extraction of Active Components of Xiaoaiping and Preparation ...
