Problems solved by technology

[0007] In the extraction methods of star anise spices at present, the remaining solid slag after steam distillation of fennel oil is all abandoned, and what have also just carries out solvent extraction etc. to star anise, and the extraction rate of these methods is very low, causes the waste of star anise resource, has Supercritical CO 2 Fluid extraction of star anise, the extraction rate of this method is relatively high, but the cost is too high and it is not suitable for large-scale production

Abstract

The invention discloses an extraction method for illicium verum natural perfume. Illicium verum is dried, cut up and distilled with steam to obtain illicium verum oil, solid slag is obtained at the same time, the illicium verum oil is used for manufacturing high-grade perfume, a petroleum ether solution with the volume fraction ranging from 70% to 80% is then added in the solid slag raw material to soak the solid slag raw material, reflux extraction is conducted through a Soxhlet extractor three times, the mass of the petroleum ether solution added for the first time is 8 to 10 times of the mass of the solid slag raw material, the masses of the petroleum ether solutions added for the last two times are each 1 to 2 times of the mass of the solid slag raw material, the extracting solution is concentrated in a pressure reduction manner to obtain extract, the extract is dissolved in ethyl alcohol, activated carbon is added, stirring is conducted, the mixture is filtered after being placed at the normal temperature, the ethyl alcohol is recycled, the illicium verum natural perfume is obtained, and the perfume can be used as high-grade cosmetics. The method is simple in process, the production steps are simplified, the production cost is low, no environment problems are caused, and the extraction method is suitable for large-scale production. Compared with a traditional method, the extraction rate can be increased by 20%, and purity can be increased by 30%.
