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.

The present invention discloses a method for preparing a compound menthol ointment, comprising the following steps: preparing menthol and / or camphor microcrystals; coating the microcrystals with a wall material to obtain microcapsules; and then mixing the microcapsules with a matrix and other oil-soluble active ingredients to prepare the compound menthol ointment. Camphor and / or menthol crystals with an average particle size of 1 to 10 μm are obtained using a solvent displacement recrystallization method. These crystals serve as the core material for preparing microcapsules. After the microcapsules rupture, oil-soluble components of the matrix or skin oils slowly dissolve the crystals, allowing the camphor and / or menthol components to slowly come into contact with air, which helps slow their volatilization and thus prolongs the cooling effect on the skin.
