Abstract
Extraction of lutein from raw macroalgae Monostroma nitidum was conducted using a simple method employing dimethyl ether (DME) as a solvent. DME extraction enabled omission of conventional drying and cell wall disruption steps, yielding 0.30 mg/g dry lutein from wet M. nitidum. The yield of extracted lutein was higher than that by chloroform–methanol extraction from freeze-dried and cell-disrupted M. nitidum. DME extraction provides a safe, eco-friendly approach that combines high yields of lutein with unheated drying of wet macroalgae in a single step.
