Problems solved by technology

At present, there are many extraction methods for deep-sea chestnut seed oil. The traditional extraction methods include Soxhlet extraction, steam extraction, hydroenzyme extraction, and supercritical CO extraction. 2 Extraction, cold pressing extraction and other methods, these extraction methods take a long time, and the amount of solvent volatilization is large, resulting in waste of resources and environmental pollution. At the same time, the extraction efficiency is low, the residual amount of solvent is large, and the requirements for equipment are high.

Embodiment 1

[0027] A method for extracting high-purity deep-sea chestnut seed oil, comprising the steps of:

[0028] (1) Accurately weigh a certain amount of deep-sea chestnut seeds, place them in a configuration container, and add chloroform extractant for extraction. The amount of chloroform used is 10 times the weight of deep-sea chestnut seeds. Microwave frequency 3×10 5 Hz, the microwave power is 600W;

[0029] (2) The obtained mixture is filtered, and the obtained filtrate is subjected to rotary separation on a rotary evaporator, and after removing chloroform, the residue is deep-sea two-sectioned chestnut seed crude oil;

[0030] (3) Put the obtained deep-sea two-sectioned chestnut seed crude oil into a fixed container, add a certain amount of sodium hydroxide when heated to a certain temperature, and continue to heat up to about 110°C. At this time, a large number of bubbles are generated, and keep warm until the bubbles basically disappear. , stop heating, wash with warm water ...

Abstract

The invention belongs to the field of natural products extraction, and concretely relates to a method for extracting high-purity crambe abyssinica seed oil and a cream containing the crambe abyssinica seed oil. According to the invention, the crambe abyssinica seed oil can be extracted by using a microwave radiation method, the method comprises the following steps: 1) accurately weighing a certain amount of crambe abyssinica seeds and placing the crambe abyssinica seeds in a container, adding a certain amount of an extraction solvent, extracting the crambe abyssinica seeds under certain microwave power to obtain a mixture; 2) filtering the mixture, performing rotating separation on a filtrate on a rotary evaporator, removing the extraction solvent to obtain a residual substance crambe abyssinica seed crude oil; 3) placing the crude oil in a fixed container, adding sodium hydroxide for boiling the material, washing the material by warm water until the material presents neutrality; and 4) performing adsorption decoloring on the crambe abyssinica seed crude oil obtained in the step 3) and filtering the crambe abyssinica seed crude oil, and obtaining the filtrate which is the crambe abyssinica seed oil. The extraction technology is simple, and purity of the obtained crambe abyssinica seed oil is high. The invention also discloses an application of the crambe abyssinica seed oil in the cream.

Description

technical field [0001] The invention belongs to the field of natural product extraction, and in particular relates to a method for extracting high-purity deep-sea chestnut oil and a skin care cream containing it. Background technique [0002] Crambe Abyssinica Seed Oil (CRAMBEABYSSINICASEEDOIL) can be extracted from its seeds. The deep sea chestnut seed oil is rich in fatty acids omega3, omega6, omega9 and long carbon chain fatty acids, which can enhance the barrier function of natural liposomes. The rich omega9 can leave a thin protective film on the skin surface to reduce transepidermal water loss and repair damaged skin. Deep-sea chestnut seed oil can nourish and repair damaged or dry skin. In recent years, the demand for deep-sea chestnut oil has been increasing in the cosmetic industry. At present, there are many extraction methods for deep-sea chestnut seed oil. The traditional extraction methods include Soxhlet extraction, steam extraction, hydroenzyme extraction, a...
