Abstract

The invention relates to a method for extracting alpha-mangostin from a mangosteen fruit peel. The method comprises the following realization steps: (I) extracting the mangosteen fruit peel; (II) concentrating an extracting solution; mixing the extracting solution of every time and concentrating under reduced pressure to obtain a concentrated solution; (III) leaching the solution; (IV) carrying out silica gel column chromatography; (V) carrying out coarse crystallization; and (VI) carrying out recrystallization: adding a primary crystal into an organic solvent with the volume of 1 to 5 times to carry out thermal dissolution; placing the solution after finishing the thermal dissolution, reducing the temperature to a room temperature, carrying out recrystallization, and controlling the crystallization time to between 10 and 20 hours; and filtering and centrifugating a recrystallization liquid, drying the liquid in vacuum to obtain the 98 percent alpha-mangostin. The method has the advantages of simple process and short operation time.

Description

technical field

[0001] The invention relates to a method for extracting polyphenol compounds from plants, in particular to a method for extracting α-mangostin from mangosteen peel. Background technique

[0002] Mangosteen (Garcinia mangostana L.), also known as mangosteen, mangosteen, and phoenix fruit, is the fruit of the evergreen tree mangosteen of the genus Garcinia in the family Guttiferae. Because mangosteen peel contains α-mangostin, it is often used to treat abdominal pain, diarrhea, dysentery, infectious trauma, suppuration, chronic ulcer, leucorrhea, gonorrhea and other diseases. In recent years, α-mangostin in mangosteen peel has become a research hotspot. The extraction methods of α-mangostin include water extraction, alcohol extraction, and macroporous adsorption resin separation method.

[0003] Chinese patent 200610016501.4 published on September 20, 2006 discloses a "mangosteen peel extract and its extraction method and medicinal use". In this method, the ma...
