Abstract

The invention discloses an extraction method for rose essential oil. The extraction method for the rose essential oil includes the following steps: preparation of raw materials: namely a step of taking fresh rose petals, and drying the fresh rose petals for 3 h-4 h in a baking oven with the temperature of 105 DEG C-115 DEG C; extraction: namely a step of adding an extraction agent to the dried rose petals for performing microwave extraction, and collecting an extract liquor after centrifugation; and separation: namely a step of performing purification and separation on the extract liquor to obtain the rose essential oil. The extraction method for preparing the rose essential oil of the invention simply utilizes the rose petals as the raw materials, a source is single, and at the same time,a combined effect of atmospheric distillation and oil-water separation are utilized to prepare the rose essential oil, so that the problem of poor purity of current rose essential oil can be solved;and due to the particularity of a process, the effective utilization rate of rose petals can be improved, and the yield of the rose essential oil is increased to meet market demands.

Description

technical field [0001] The invention belongs to the technical field of plant extraction, and in particular relates to a method for extracting rose essential oil. Background technique [0002] With the continuous improvement of people's living standards, the requirements for quality life are getting higher and higher. As a pure natural essence, plant essential oils are more and more popular and loved by people. Essential oils are a kind of volatile, strong fragrance and smell. , The general term for oily liquids that can be distilled out with water vapor. Essential oils have active ingredients and have a wide range of applications, such as eliminating phlegm and relieving cough, dispelling wind and strengthening stomach, repelling insects, anti-wrinkle maintenance, etc. The essence of the most popular water therapy (SPA) is natural plant essential oils.
