preparation example Construction

[0040] The preparation method of the piceatanol-containing composition of the present invention will be described below.

[0041]In the preparation method of the piceatanol-containing composition of the present invention, firstly, the passion fruit seeds are pulverized. Passion fruit seeds can be used raw or dried. In order to improve the extraction efficiency, the passion fruit seeds can also be properly subjected to acid or alkali decomposition, enzyme decomposition and other chemical treatments before extraction . The pulverization treatment can be performed using a general-purpose pulverizer. Also, since passion fruit seeds contain a lot of oil, they may be mushy when crushed.

[0042] Subsequently, at least one solvent selected from a water-containing alcohol-based solvent and a water-containing ketone-based solvent is added to the pulverized passion fruit seeds and stirred, and piceatanol is extracted from the solvent.

[0043] As the aqueous alcohol-based solvent, aq...

Abstract

A purpose of the present invention is to provide a high piceatannol content piceatannol-containing composition derived from natural materials, and a preparation method thereof. According to the present invention, the piceatannol-containing composition containing 0.0001-99.9% by mass of piceatannol is extracted from passion fruit seeds; and during extraction of the piceatannol, after the passion fruit seeds are crushed, at least a solvent selected from a water-containing alcohol solvent or a water-containing ketone solvent is added to stir, the piceatannol is extracted from the passion fruit seeds contained in the solvent, and stage extraction is performed by preferentially using the two solvents such as the water-containing alcohol solvent and the water-containing ketone solvent.

Description

technical field [0001] The present invention relates to a piceatanol-containing composition derived from passion fruit (passion fruit) seeds, and a food, drink, and cosmetic containing the piceatanol-containing composition. Background technique [0002] The following Non-Patent Document 1 describes that grape-derived polyphenolic compounds resveratrol and piceatannol have an action of inhibiting melanin-producing cells from producing melanin. However, a commercially available reagent was used in the confirmation test of the action and effect, and there is no description of obtaining a composition containing piceatanol or the like from natural products such as grapes. [0003] In addition, the following Patent Document 1 describes the selective and effective concentration and recovery of resveratrol from the root extract of Polygonum cuspidatum (Reynoutria japonica Houtt.var.japnica) at low cost; and the following Patent Document 2 describes A bilberry extract containing res...
