Method for extracting peony essence from fresh peony flowers

ActiveCN103305344APreserve the spice ingredientsRetain activityEssential-oils/perfumesBiotechnologyOrganic solvent
The invention belongs to the field of extraction of plant essential oil and in particular discloses a method for extracting peony essence from fresh peony flowers. The method comprises the following steps: performing supercritical CO2 extraction on the fresh peony flowers as raw materials to prepare peony extract, and extracting the peony extract to obtain the peony essence by employing a molecular distillation method. According to the method, since the fresh peony petals are taken as the raw materials, the spice components, thermal-sensitive substances and other active ingredients in the peony petals are maintained to the greatest extent, desensitization treatment is performed in the extraction process of essential oil, the condition that some people have pollen allergy is avoided; since the peony essential oil is extracted through the supercritical CO2 extraction method, the phenomenon that the thermal-sensitive substances in the peony flowers are lost because of heating in the traditional method is avoided; and meanwhile, the residue problem of the harmful substances caused by extraction by employing an organic solvent and the treatment and recovery problems of the organic solvent are solved, the environmental pollution is reduced, and the energy consumption is reduced.
