Abstract
Powdered florets from dyer's saffron (Carthamus tinctorius L.) were suspended in a buffered solution containing KMnO4 or H2O2 and the mixtures oscillated with a supersound sonicator for 10 min at 25 ± 1°C. Carthamin yield in the floral pastes was determined and the data were compared with those of the floret pastes with no supersonic oscillation treatment. With short time sonication, carthamin yield could be increased by about 8% higher on average.
