dc.description.abstractThe aim of this study is to extract and characterize curcuminoids pigment from turmeric curcuma longa L. grown in Comoros. The extraction of curcuminoids from turmeric was carried out using a solvent extraction technique with dichloromethane as a solvent which followed by a recrystallization step with methanol. FT-IR spectroscopy, UV, melting point and TLC were used to characterize the isolated pigment. The IR analysisconfirmed the presence of the characteristics absorption peaks of curcuminoids. Two distinctive absorption bands were noticed in UV with maximum absorption peak at 420 nm. The melting point of the product was found to be equal to 173˚C. Three different overlapped-colored zones were observed in TLC using two different solvent systems (methanol/ethylacetate and ethylacetate/toluene).en_US
