The invention relates to a preparation method and use of
Xanthoceras sobifoba kernel oil extracted from
supercritical fluid and a preparation of the
Xanthoceras sobifoba kernel oil. The preparation method comprises the steps of
grinding Xanthoceras sobifoba kernels, sieving by virtue of a 10-100-mesh
sieve, and carrying out
supercritical fluid extraction in an extraction kettle, so as to obtain the Xanthoceras sobifoba kernel oil and a kernel residue rich in proteins, wherein the kernel residue can be used for extracting total saponins and has an extremely high medical value. Compared with a traditional squeezing process, a CO2
supercritical fluid extraction method has the advantages that the process is simple, the
production cycle is short, the extraction efficiency is high, and the serious damage of
unsaturated fatty acid in
grease and the denaturationof the proteins in
medicine residues at the high temperature are avoided. Compared with a method for extracting by virtue of organic solvents such as
petroleum ether, the CO2
supercritical fluid extraction method has the advantages that the
residual solvent is avoided, operation condition are mild, and the production is safe, toxic free and
environmentally friendly. The oil extraction rate of the Xanthoceras sobifoba kernels is not lower than 50%, and GC-MS detection shows that the content of
unsaturated fatty acid reaches up to 75% or above. By adding medical auxiliary materials, the
dose forms of soft capsules, micro-capsules,
cyclodextrin coated preparations, dripping pills and the like can be prepared and can be used for developing health products for preventing and treating hypertension, hyperlipemia and diseases of cardiovascular systems.
