Embodiment Construction

[0022] First, take 8 to 10 freshly picked mangosteens, peel them, put the obtained mangosteen skins into an ultrasonic cleaner, add 3% sodium percarbonate, the liquid level is higher than the mangosteen skins, turn on the switch of the ultrasonic cleaner to wash for 3 to 5 minutes, and take out , cleaned with distilled water to obtain clean mangosteen bark; put the obtained mangosteen bark into a drying box, dry it at room temperature for 1 to 2 days, take it out, put it into a small ball mill and pulverize it, and pass through the mangosteen bark powder through a 250-mesh sieve; Add distilled water to the mangosteen bark powder until it is submerged 2 to 3 cm above the mangosteen bark powder, heat at a controlled temperature of 70 to 80 °C until the water boils, then add 5 to 7 g of carbon black loaded with hydrophilic organic matter to obtain adsorbed mangosteen bark powder loaded hydrophilic organic carbon black; take out the loaded hydrophilic organic carbon black adsorbed ...

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...
