Embodiment 1

[0031] Weigh 300g of freshly picked roses, put them into a steam distillation device, add 2.5% sodium chloride aqueous solution that is 3.5 times the weight of flowers, add pure water to the oil-water separator, add 0.14mL of protective agent, and heat it with a heating mantle in a distillation flask. When the solution boils, start to calculate the distillation time, adjust the cooling water flow, the cooling liquid with essential oil enters the oil-water separator, collect the upper oil layer, and the lower water layer is passed into the reflux distillation bottle, the distillation time is 3.5 hours, collect the essential oil, and calculate The oil yield of essential oil is 0.45‰, and the IC50 value of half scavenging concentration of DPPH free radical is 0.025mg / mL.

Embodiment 2

[0033] Weigh 350g of freshly picked roses, put them into a steam distillation device, add 4% sodium chloride aqueous solution that is 4 times the weight of fresh flowers, add 0.15mL of protective agent after adding pure water to the oil-water separator, heat with a heating mantle, and use it as a distillation flask When the medium solution boils, start to calculate the distillation time, adjust the cooling water flow, the cooling liquid with essential oil enters the oil-water separator, collect the upper oil layer, and return the lower water layer to the distillation bottle, the distillation time is 4 hours, collect the essential oil, and calculate the essential oil The oil yield is 0.40‰, and the half-scavenging concentration IC50 of DPPH free radicals is 0.030 mg / mL.

Embodiment 3

[0035] Weigh 400g of freshly picked roses, put them into a steam distillation device, add 5% sodium chloride aqueous solution that is 4.5 times the weight of flowers, add pure water to the oil-water separator, add 0.2mL of protective agent, heat with a heating mantle, and use it as a distillation bottle When the solution boils, start to calculate the distillation time, adjust the cooling water flow, the cooling liquid with the essential oil enters the oil-water separator, collect the upper oil layer part, and the lower water layer returns to the distillation bottle, the distillation time is 4.5 hours, collect the essential oil, and calculate the essential oil yield The oil rate is 0.43‰, and the half-scavenging concentration IC50 of DPPH free radicals is 0.035mg / mL.

Abstract

The invention provides a plant essential oil extraction device and a plant essential oil extraction method. The extraction device comprises a distillation flask, an oil-water separator, a condensation pipe and a protection gas connection pipe, wherein the oil-water separator comprises a main pipe, a side branch pipe and a lower branch pipe; the side branch pipe is arranged on the side surface of the main pipe; the lower branch pipe is arranged at the bottom of the main pipe; the condensation pipe is communicated to an upper opening of the main pipe; the distillation flask is communicated with the opening part of the side branch pipe; the protection gas connection pipe is arranged into the main pipe in a penetrating manner and extends into the lower branch pipe. The extraction method comprises the following steps: feeding plant petals and a solvent into the distillation flask, and an essential oil protecting agent is added into the oil-water separator and nitrogen is fed into the oil-water separator for distillation; an oil layer component is collected in the oil-water separator to obtain plant essential oil. Compared with the prior art, the plant essential oil extraction device provided by the invention has the following beneficial effects that fresh rose flowers picked before 10 o'clock in the morning are selected, and are distilled through a sodium chloride aqueous solution; the oil yield of the rose flowers and the quality of the essential oil can be improved.

Description

technical field [0001] The invention relates to a plant essential oil extraction device and a plant essential oil extraction method, belonging to the technical field of plant essential oil extraction. Background technique [0002] Rose essential oil is extracted from rose flowers. Rose essential oil is not only used in cosmetics, but also widely used in medicine and food. Rose flower essential oil can anti-inflammatory and sterilize, promote cell regeneration and wound healing, and prevent skin aging. [0003] At present, the main methods of extracting rose essential oil include steam distillation, organic solvent extraction, supercritical CO2 extraction and so on. The essential oil obtained by the traditional steam distillation method has low extraction rate, poor quality of essential oil, long distillation time, high power consumption, etc.; the essential oil obtained by the organic solvent extraction method, the solvent residue affects the quality of the essential oil a...
