This invention discloses a low-loss, high-yield extraction method for natural menthol, belonging to the field of menthol production technology. It addresses the technical problem of insufficient extraction yield and loss rate in existing natural menthol extraction processes, requiring further optimization. The method specifically includes the following steps: adding menthol extraction mother liquor to a crystallization vessel and stirring; slowly adding sodium chloride aqueous solution; maintaining the crystallization vessel in an ice bath at 0-5°C; allowing it to stand for 2-4 hours; and then post-processing to obtain natural menthol crystals. This invention synergistically extracts menthol with a modified polymer eutectic solvent and modified cyclodextrin in an aqueous phase with pulverized mint leaves to obtain an extraction mother liquor. Sodium chloride is added, and a low-temperature induced supramolecular system is used to destabilize the liquor, causing menthol to crystallize in a specific direction, resulting in natural menthol crystals. This achieves a synergistic unity of low volatility loss, efficient solubilization and transfer, and directional crystallization separation during the extraction process, significantly improving the extraction yield of the target product.
