Abstract

Reline DES was classified as a green solvent and compatible to be used for α-tocopherol (α-T) extraction from crude palm oil (CPO) due to its ability to form strong hydrogen bond with α-T molecule. The α-T concentration and yield was quantified using reverse phase high performance liquid chromatography (RP-HPLC). Two parameters were studied through utilization of five CPO: Reline DES ratio series (1:1, 1:2, 1:3, 1:4 and 1:5) at 2 and 3 hours extraction time in determining optimize α-T extraction condition. Concentration of α-T for all extracted samples was compared to the control (without reline DES) resulted towards CPO: Reline DES ratio of 1:2 with solvent viscosity of 5.7 ± 0.58 cP at 3 hours extraction time as the best condition to obtain the highest α-T concentration of 825.321 ± 74.27 mg/L with the yield of 0.1554 ± 0.0156 (%). It can be concluded that this condition is the most conducive for α-T molecules diffusion into free space of solvent structure in which molecules of α-T and reline DES interact through hydrogen bond. The strong hydrogen bond formed between –OH group of α-T and-NH2 group of reline DES is the factor enhancing the capability of reline DES to extract higher α-T compound from CPO.
