AN IMPROVED PROCESS FOR THE EXTRACTION OF CARTHAMIN DYE FROM SAFFLOWER (CARTHAMUS TINCTORIUS)

摘要

An improved process for the extraction of carthamin dye from safflower Carthamus tinctorius with polar solvents in a ratio 1:5 adjusting pH of extract between 4-5 by known method, concentrating the extract in vacuo at a o temperature in the range of 60-70 C, washing the above extract with non-polar solvent, concentrating the washed extract, preserving concentrated extract containing carthamin dye in a sterlized sealed container.
