carthamin solutions and safflower extract solutions. Each solution
was exposed to room conditions in the daylight and three samples
of each group were removed at days 0, 3, 7, 15 for HPLC analysis.
The effect of water content in NADES on the stability of carthamin
was investigated with two NADES (PMH and SuCH) at 4 C
and 20 C in the dark. PMH and SuCH were used with 0%, 25%,
50%, and 75% (v/v) water. All stability tests were done in triplicate.
