| titleOfInvention | Process for extracting chalcone type ingredients from ashitaba |
| abstract | The invention belongs to the technical field of extracting chemical ingredients and specifically relates to a process for extracting chalcone type ingredients from ashitaba, which comprises the following steps: selecting dry stems and leaves of the ashitaba, smashing, carrying out hot dipping extraction with ethanol, merging extraction solution, decompressing, recovering the ethanol till having no alcohol smell and further getting liquid extract; and extracting with ethyl acetate after using water to dissolve the liquid extract, decompressing, recovering the ethyl acetate, getting an extract which is a chalcone crude product, adopting an AB-8 macroporous adsorption resin column to separate and purify the chalcone crude product, collecting eluant, further separating and purifying the eluant via a 100-mesh silica gel chromatography column and getting chalcone. The ethanol is adopted as an extraction solvent, thereby effectively reducing the activity of a chalcone enzyme, avoiding the decomposition of the chalcone during extraction and improving the extraction rate; and the process is simple, and the consumed time is short, thereby providing an industrial way for extraction of chalcone plants. |
