Embodiment 1

[0015] 1. Extraction method of lavender essential oil:

[0016] Remove impurities and branches in the lavender grass material, accurately weigh 50g of lavender flower spikes, put it in a 1000ml three-necked flask, spray 50ml of acetone evenly on the surface of the lavender, connect a spherical condenser tube, and oscillate at a temperature of 30°C in an ultrasonic oscillator 60 minutes, ultrasonic power is 120W. After the ultrasound is completed, the solvent is distilled off under reduced pressure, and then the lavender is steam-distilled to extract the lavender oil in a steam device. The steam distillation time was 4 hours. One port of the three-neck flask is connected to the water vapor generator, the other port is connected to the water vapor balance tube, and the other port is connected to the straight condenser tube. At the same time, the condenser tube is connected to the oil-water separator to separate the oil phase and the water phase. The lower layer of water and the...

[0020] 1. Extraction method of lavender essential oil:

[0021] Remove impurities and branches in the lavender grass material, accurately weigh 50g of lavender flower spikes, put it in a 1000ml three-necked flask, measure 75ml of acetone and spray it evenly on the surface of the lavender, connect a spherical condenser tube on it, and oscillate at a temperature of 30°C in an ultrasonic oscillator 30 minutes, the ultrasonic power is 180W. After the sonication is completed, the solvent is removed by distillation under reduced pressure, and then the lavender is steam-distilled in a steam device to extract lavender oil. The steam distillation time was 4 hours. One port of the three-neck flask is connected to the water vapor generator, the other port is connected to the water vapor balance tube, and the other port is connected to the straight condenser tube. At the same time, the condenser tube is connected to the oil-water separator to separate the oil phase and the water phase. T...

[0025] 1. Extraction method of lavender essential oil:

[0026] Remove impurities and branches in the lavender grass material, accurately weigh 50g of lavender flower spikes, put them in a 1000ml three-necked flask, measure 100ml of n-hexane and spray evenly on the surface of the lavender, connect a spherical condenser tube on it, and place it in an ultrasonic oscillator at a temperature of 30°C Oscillate for 30 minutes, and the ultrasonic power is 120W. After the sonication is completed, the solvent is removed by distillation under reduced pressure, and then the lavender is steam-distilled in a steam device to extract lavender oil. The steam distillation time was 3 hours. One port of the three-neck flask is connected to the water vapor generator, the other port is connected to the water vapor balance tube, and the other port is connected to the straight condenser tube. At the same time, the condenser tube is connected to the oil-water separator to separate the oil phase and ...

Abstract

The present invention discloses a preparation method of lavender nano essential oil. Said method includes the following steps: a), using sprayer to spray acetone or n-hexane on the lavender surface uniformly according to solvent and raw material ratio of 1:1-3, utilizing ultrasonic technique to treat lavender; b), reduced pressure distillation to remove solvent, utilizing steam equipment to extract lavender oil; and c), utilizing ion condensation action of chitosan and sodium tripolyphosphate to prepare nano carrier for embedding lavender essential oil so as to obtain the lavender nano essential oil.

Description

technical field [0001] The present invention relates to a kind of preparation method of lavender essential oil, more specifically relate to a kind of preparation method of lavender nano essential oil with chitosan as carrier. Background technique [0002] Lavender contains complex chemical components, generally containing linalyl acetate, linalool, lavender acetate and other ingredients, and the higher the content, the better the quality. Steam distillation is the main method for producing lavender essential oil at present, but generally speaking, the extraction rate is very low, generally no more than 1%, and the utilization rate of aromatic components in plants is also very low. Due to the lack of finishing technology, most of the domestically produced lavender essential oils are sold in the form of crude oil. The quality is unstable, the specifications are not uniform, the quality is low, and it cannot be used in the field of beauty and health care due to poor absorption....
