The present invention discloses a mangosteen pericarp extract and process for its preparation thereof. The mangosteen pericarp extract containing α-mangostin and γ-mangostin which obtains from preparation steps comprising fragmentation, organic solvent soaking, aqueous solution, or acidic solution soaking, concentration, spray drying and grinding steps from the rind of the mangosteen. The present invention has advantages of simple preparation process to address efficiency issue, no need to have heating under reflux in extraction steps and the solvents which used are friendly to human body and environment. The mangosteen pericarp extract (α-Xones Prime) can significantly decrease insulin resistance, and bodyweight gain induced by daily high fat diet intake. In addition, administration of the mangosteen pericarp ethanolic extract can reduce fat accumulation in the adipose and muscle tissue of rats with daily high fat diet intake. The α-Xones Prime could be used as a nutraceutical ingredient for weight control or weight loss, or even prevention of metabolic syndrome and diabetes, and developed into a candidate drug composition.

The present invention is directed to a method for preparing plant extracts comprising the steps of (i) preparing a soluble extract from (a) plants or parts thereof and (b) an aqueous, alcoholic or aqueous alcoholic mixed extractant; and removal of insoluble components, (ii) concentrating the extract to a dry substance content at which the contained lipids and lipoids form suspended and/or emulgated aggregates, (iii) separating the suspended and/or emulgated aggregates by microfiltration from the concentrated extract, and (iv) optionally removing the extractant. The invention further pertains to an extract and composition comprising said extract as prepared by this method.
