Extraction and Determination of Crocin in Saffron Samples by Dispersive Liquid-Liquid Microextraction [PDF]

Zirā̒at va Fanāvarī-i Za̒farān, 2016
The main component responsible for color in saffron is crocin with the chemical formula of C44H64O24. Crocin is one of several carotenoids in nature that is soluble in water. This solubility is one of the reasons for its widespread usage as a colorant in
