Problems solved by technology

However, the activated carbon used for decolorization is discarded and cannot be reused
These activated carbons adsorb a large amount of pigments and essential oils, which will cause waste of resources if discarded, and also push up the extraction cost of rosemary

Embodiment 1

[0019] see figure 1 , the process is as follows:

[0020] 1) Extraction: Put 100 grams of decolorized activated carbon into the reactor, add 300 grams of n-hexane for extraction, extract once per hour, and extract twice in total;

[0021] 2) Filtration: Combine the two extracts and pass through a 500-mesh filter cloth;

[0022] 3) Molecular finishing: first, heat the filtrate to 40°C, feed at a rate of 1.8mL / min, and vacuum at 100pa; secondly, cool the filtrate to 1°C; thirdly, put the reactor into a device with a speed of 250r / min Carry out desolvation treatment; fourth, reheat the desolvated liquid to 70°C, feed rate 1.8mL / min, vacuum degree 100pa; fifth, cool the liquid to 1°C; sixth, reheat the reactor Put it into a device with a rotating speed of 250r / min to carry out essential oil purification treatment, collect the distillate to obtain the rosemary essential oil.

Abstract

The invention discloses a method for preparing rosemary essential oil in a rosemary extract decolorization technique. According to the method, activated carbon used in the rosemary extract decolorization technique is used as the raw material and used for extraction by using an organic solvent, and molecular distillation is performed to recover the solvent and purify the rosemary essential oil. The method comprises the following steps: extracting with the organic solvent, filtering, and carrying out molecular rearrangement. According to the method, the leftovers in the rosemary extract preparation process are fully utilized and subjected to the simple extraction and molecular distillation techniques to obtain the rosemary essential oil of which the purity is 95% or above and the yield is 0.12-0.15%. The method fully utilizes the resources and lowers the rosemary extraction cost. The rosemary essential oil prepared by the method has equivalent quality to the rosemary essential oil sold in the market.

Description

technical field [0001] The invention belongs to the technical field of plant component extraction, and in particular relates to a method for obtaining rosemary essential oil from a rosemary extract decolorization process. Background technique [0002] Rosemary, Lamiaceae shrub. Antioxidants with excellent antioxidant properties, rosemary essential oil and ursolic acid can be extracted from the flowers and leaves of rosemary. Rosemary is an antioxidant, widely used in medicine, fried food, oil-rich food and various oils and fats; Industrial Products. [0003] The main function of rosemary is anti-oxidation. The research results of the national 863 plan project undertaken by Tianjin University of Science and Technology, No. 2007AA100401 show that a dose of 3 mg / mL of rosemary extract can significantly improve the activity of SOD and CAT in Drosophila, reduce MDA content. Rosemary extract can improve the activity of antioxidant enzymes in Drosophila, inhibit lipid peroxidat...
