Crocin belongs to the carotenoids group and is found a lot in Gardenia jasminoides Ellis. It is not only capable of creating color for food, but also has a lot of pharmaceuticalologicaleffects such as improving memory, anti-convulsants, anti-depressants, anti-oxidation, anti-tumor, etc.…The Oobjectives of this study wereisto detemine the crocin extraction methodology from Gardenia jasminoides Ellis and the color durability stability in different conditions. Carotenoid content was determined as described by Kotikova et al., 2011. Crocin content was determined by the Ultraviolet-visible spectroscopy (UV - VIS) at 440 nm wavelength. The results indicated that Gardenia jasminoideswas is apotential material to provide theobtainlarge highcrocin at concentrations,up to 16.04mg/g,for fresh material and 14.63mg/g for driedymaterial. The crocin extraction efficiency reached the peak with ethanol: water solvent (40:60, 50:50, v/v). The best results foroptimalsolvent : raw materials ratioand;fresh and dry materials extracting conditions corresponding were20ml/1g at 40°C in 45 minutes; 25ml/g at 70°C in 60 minutes, respectively. Crocin is stable at the temperatures below 100°C withinduring140 minutes. Besides, crocin is also stable in weak acidand,neutral and alkaline conditions.
