Abstract

This study aims to determine the effect of extraction time (5,10,15 minutes) and the ratio of the aquadest solvent: ethyl acetate (1: 6.5, 1: 7, 1: 8 v / v) to the yield of pigment . The optimum condition was found on the ratio of solvent of distilled water: ethyl acetate (1: 7 v / v) extraction time for 15 minutes with low microwave power resulted in maximum pigment yield of 0.469%. The isolate compounds were analyzed using IR spectroscopy, mass spectroscopy, and High Performance Liquid Chromatography (HPLC) showed that the isolates were bixin pigments having molecular weight of 394 g / mol with wave numbers for OH groups, C = O carboxylate groups, CH bonds, duplicate C = C, and CO ester bonds. As well as showing the retention time of standard and standard pigments at minutes to 12.849 and 12.843
