Benefits of technology

This patented technology allows creation of a pure chemical called picta seed oil (PTO) without harmful side effect on human body like carbamazepine. By adding certain substances during processing, PTO becomes more effective than other methods due to its ability to dissolve various compounds naturally found therein. Additionally, the use of these techniques makes manufacturing processes faster while also reducing environmental impact caused by waste generated through previous uses.

Problems solved by technology

This patents discuss different methods for producing concentrated forms of specific chemical components called pimutans, which include polygulose, hesperetins, chlorophyllene, quercitrin, cisplatin, tetrabenzoxazole, cycloartenamine, etc., while also addressing issues related to their ability to lower down certain ingredients without affecting beneficial effects on other ones.

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

The invention aims to provide a piceatannol-containing composition which comes from a natural product and contains piceatannol with high content and a method for preparing the piceatannol-containing composition. The piceatannol-containing composition which contains the piceatannol at a content of 0.0001-99.9 mass percent is extracted from passion fruit seeds. In addition, when the piceatannol is extracted, the passion fruit seeds are crushed, at least one solvent selected from a water-containing alcohol solvent and a water-containing acetone solvent is added into the seeds for stirring, and the piceatannol is extracted from the passion fruit seeds contained in the solvent. Thus, staged extraction is performed by using the two solvents best, namely the water-containing alcohol solvent and the water-containing acetone solvent.
