Definitions

  • polar non-lipid components such as sugars, sterol glucosides, water, proteins etc. may be co-micellised, ie • these components are accommodated in the polar core of the phospholipid micelles. Due to the formation of the micelles, the phospholipids become easily soluble in hexane
  • soyabean phospholipids also contain minor amounts of other compounds, eg Phosphatidyl Serine (PS), Gar iolipiii (CL), Sphingophosphatides (SP), and partially hydrolysed species which are generally called Lysophospholipids, eg Lysophosphatidyl Choline (LPC).
  • PS Phosphatidyl Serine
  • CL Gar iolipiii
  • SP Sphingophosphatides
  • Lysophospholipids eg Lysophosphatidyl Choline (LPC).
  • the membranes In carrying out the process of the invention, it may be necessary to subject the membranes to be used to treatment rendering it suitable for non-aqueous use.
  • an intermediate solvent and the diluent solvent to be used in the process Where the latter is hexane, isopropanol may be used as the intermediate solvent, but others will occur to those skilled in the art as suitable.
  • the intermediate solvent must be miscible, if only to a limited extent, both with water and the diluent solvent. It is preferable also to treat the membrane by a similar washing procedure after protracted use, to restore the effectiveness of the membrane.

Abstract

Procédé de fractionnement de composés, lesquels, dans des solvants essentiellement non-polaires forment des micelles fixes ou co-micelles, et par conséquent ne peuvent être fractionnées normalement au moyen d'une filtration par membranes. En dissolvant un mélange de ces composés dans un système de solvant dans lequel a lieu une formation sélective de micelles, et en mettant en contact la solution sous pression avec une membrane semi-perméable pour séparer le mélange en un perméat et en rétentat, on peut obtenir le fractionnement du mélange de composés, c'est-à-dire on peut récupérer du perméat et/ou du rétentat, par extraction du solvant, une fraction enrichie en l'un de ces composés. Le nouveau procédé est utile notamment pour le fractionnement de mélanges contenant des phosphatides en une fraction enrichie en phosphatidyl choline par ultrafiltration d'une solution du mélange dans un système de solvant comprenant un solvant essentiellement non-polaire et un solvant polaire, par exemple de l'hexane-éthanol, etc. au travers d'une membrane semi-perméable, et en récupérant du perméat une fraction enrichie en phosphatidyl choline. Une fraction enrichie en phosphatidyl inositol peut être extraite du rétentat.
