Preparation method of tripterine

Abstract

The invention relates to a preparation method of tripterine, and the method comprises the following steps: crushing triperygium wilfordii roots, adding 5-7 times amount of 85-90% alcohol, refluxing for 2-3 times, and decolorizing the extracting solution by virtue of active carbon; recycling the alcohol from the destaining solution until the alcohol concentration is 55-65%, standing the destaining solution to precipitate, filtering out precipitates, dissolving the precipitates in 5-7 times amount of an alkaline alcohol solution, filtering out insolubles, adjusting the pH value of the filtered solution to 3-5, standing the solution to precipitate, filtering out precipitates, dissolving the precipitates in 3-5 times amount of the alkaline alcohol solution, filtering insolubles, adjusting the pH value of the filtered solution to 7, standing the solution to precipitate, filtering out precipitates, adding ethyl acetate into the precipitates to reflux and dissolve the precipitates, filtering the dissolvent solution, standing the filtered solution to crystallize, filtering out the crystal, adding 90-95% alcohol into the crystal, refluxing and dissolving the crystal, decolorizing the crystal alcohol solution by the active carbon, insulating and crystallizing the decolorized solution, finally drying the obtained crystal to obtain the tripterine pure product. The preparation method of the tripterine is convenient and simple, the impurity of the obtained product is high, the toxicity of used reagents is small, and the preparation method of the tripterine is suitable for industrial production.

AI Technical Summary

Benefits of technology

This patented method uses ethylene glycol (EOG), an organic chemical called acetone that helps extract flavors from foods by breaking down certain molecules into smaller ones like water or carbon dioxide gas. It also reduces harmful side products such as formaldehyde during processing compared with traditional methods involving other solvents. Additionally, it allows for easier separation of impurities due to its ability to separate out these compounds easily at room temperature without losing their effectiveness over time. Overall, this technology makes better ways to produce tasteier beverages while reducing environmental impact.

Problems solved by technology

This patented technical problem addressed in this Patents describes how to efficiently produce triptorpinia (TTP) without causing harmful side effects such as inflammations caused by tissue damaging agents like nitrogen oxide gases released during chemotherapy treatments.
