Abstract—Policosanol is a group of long chain primary aliphatic alcohols (20-36 carbon), which are constituents of plant epicuticular waxes. Policosanol enriched dietary supplements and functional foods are commercially available in the world market for their low density lipoprotein lowering properties. The presence of policosanol in the surfaces layer of wheat straw has been reported previously. The of this study was to examine the Policosanol extraction technique and composition from wheat straw by-product of Thai wheat varieties. This study show that the suitable solvent selection is the most important step in policosanol extraction and purification for optimizing recovery of aspiring to the main components from a complex mixture. Policosanol from wheat straw contain octadecanol, eicosanol, tetracosanol, hexacosanol and octacosanol. Specifically, wheat straw exhibit highest octacosanol content ratio in MJU 3, MJU 2 and Fahng 60 varieties, respectively. This study demonstrated that wheat varieties grown under identical growing conditions and management have differ significant effects on policosanol composition.
