Method for separating and purifying alpha-mangostin from garcinia mangostana

Abstract

The invention relates to a preparation method for plant extract, in particular to a method for separating and purifying alpha-mangostin from garcinia mangostana. According to the method, hydrophily-loaded organic carbon black is prepared and utilized for adsorbing garcinia mangostana bark powder, and the alpha-mangostin is extracted through the steps of acid precipitation, separating filtering and extracting. The method has the advantages that the extraction rate is high, and the purity of the extract reaches over 99.9%; the operation steps are simple, and the technological process is simplified; the needed cost is low.

Description

technical field [0001] The invention relates to a preparation method of a plant extract, in particular to a method for separating and purifying α-mangostin from mangosteen. Background technique [0002] Mangosteen, formerly known as mangosteen, is native to Southeast Asia. It usually starts to bear fruit after 10 years of planting. It is smooth but not greasy. It is as famous as durian and known as the "Queen of Fruits". Because mangosteen peel contains active ingredients such as α-mangostin, it is often used to treat abdominal pain, diarrhea, infectious trauma and other diseases. At the same time, when the concentration of mangostin in mangosteen is ≥0.40mg / ml, it has a good anti-ultraviolet sunscreen effect, and the anti-ultraviolet effect is also better than that of TiO at low concentrations (≤0.40mg / ml). 2 . [0003] At present, there are many methods for extracting α-mangostin from mangosteen, for example, the publication number CN101396101B, titled “A mangostin extra...

Problems solved by technology

[0004] The technical problem mainly solved by the present invention: Aiming at the drawbacks of the current production process of α-mangostin extracted from mangosteen, the content of the extract is low, and the operation steps are cumbersome and complicated, it provides a carbon black that is loaded with hydrophilic organic matter by preparing and utilizing , and through the steps of separation, filtration and extraction, α-mangostin is extracted. This method has simple operation steps, simplified process flow, high extraction content, and the purity of the extract reaches more than 99.9%.
