Preparation of gardenia jasminoides by macroporous adsorbing resin

Abstract

A process for preparing the extract from capejasmine fruit by use of macroreticular adsorption resin includes such steps as extracting in hydrophilic solvent to obtain coarse extract, membrane separation for removing impurities, adding water to become suspension, adsorbing by macroreticular resin, water washing for removing polar impurities, eluting with the aqueous solution of hydrophilic solvent, vacuum recovery of solvent, and vacuum concentrating.

Description

technical field

[0001] The invention relates to a green chemical preparation method for separating and purifying medicinal active ingredients from plants, and more particularly relates to a method for preparing gardenia jasmine extract by using a macroporous adsorption resin. Background technique
