Abstract : Vitamin D deficiency has been linked to various diseases, but could be rectified via fortified food stuffs or sup- plementation. In this study 39 different hydrophobic deep eutectic solvents were evaluated for green extraction of ergosterol from mushroom. Extraction parameters (e.g. time, solvent volume) were optimized using response surface methodology (RSM) and a maximum extraction yield of 6995.00 μg ergosterol/g dry weight mushroom was attained with menthol: pyruvic acid. The extracted ergosterol was purified using a novel methodology and the extraction solvent was reused for six cycles, while retaining extraction efficiency (up to 28%). The ergosterol was exposed to ultra-violet radiation for conversion to ergocalciferol (vitamin D2) resulting in a yield of ergocal- ciferol that was equivalent to 2142.01 μg/g dry weight mushroom. Keywords - Vitamin D2, Ergosterol, Hydrophobic Deep Eutectic Solvent, Menthol Pyruvic Acid, Extraction
