Problems solved by technology

This method adopts the method of supercritical fluid extraction, the recovery rate is poor, the system pressure is high, and it is difficult to extract substances with strong polarity and large molecular mass
[0006] Although these methods in the above-mentioned prior art can obtain the tea tree essential oil, the purity of the tea tree essential oil is not high, and the process is loaded down with trivial details, so it is not suitable for mass production

Embodiment 1

[0023] Take 20 kg of tea tree raw material, crush it to 40 mesh, add 160 L of petroleum ether for percolation extraction, filter the extract, and combine the extract.

[0024] Add the above extract into the distillation tank under normal pressure, heat it, and recover the solvent at the same time, and end when the steam temperature is 40°C; then add it into the evaporating flask, heat it in a water bath at a constant temperature, the heating temperature is 50°C, and the speed of the evaporating flask is 55 revolutions in minutes, the vacuum is -0.095Mpa, and it ends when there is no liquid drop in the recovery bottle. At this time, the material in the evaporation bottle is tea tree extract. Tea tree extract is about 5.6% of medicinal material quality.

[0025] Add the above tea tree extract into a molecular still, feed temperature 40°C, system vacuum 15Pa, distillation column temperature 50°C, film wiper speed 250r / min, distillation speed 1ml / min to remove residual solvent, an...

Abstract

The invention discloses a method of extracting tea tree essential oil from tea trees. The method includes: 1, washing tea leaves, crushing them to 20 meshes to 80 meshes in particle size, adding organic solvent, performing percolation extracting, and filtering extract; 2, concentrating filtrate under normal pressure, recycling solvent, and performing vacuum concentration to obtain tea tree concrete; 3, subjecting the tea tree concrete to molecular distillation, and removing the solvent and polymer materials successively to obtain the tea tree essential oil. The tea tree essential oil is purified and extracted by means of molecular distillation, organic solvent percolation and molecular distillation are made full use, and the tea tree essential oil is extracted quickly and efficiently.

Description

technical field [0001] The invention belongs to the technical field of plant essential oil extraction, in particular to a method for extracting tea tree essential oil. Background technique [0002] Tea tree essential oil, also known as Melaleuca alternifolia oil, mainly comes from several plants of Myrtaceae and Melaleuca alternifolia, the most important one is called Melaleuca alternifolia, and Melaleuca alternifolia Native to Australia, it is mainly produced in the southeast coast of Australia, so this essential oil is also called "Australian tea tree oil". [0003] Tea tree essential oil is rich in pine oil, lemon olein, eucalyptol, sesame oil, anisole, etc. It has anti-bacterial and anti-inflammatory properties, shrinks pores, treats colds, coughs, rhinitis, asthma, improves dysmenorrhea, irregular menstruation and genital infections, etc. effect. Suitable for oily and acne-prone skin, treating purulent wounds and burns, sunburn, foot and dandruff. Clears the mind, re...
