Embodiment 1

[0019] 1) Remove impurities from the picked seaside mallow flowers, put them in an oven at 45°C for 5 hours, take them out, and crush them into 40-mesh powder with crushing equipment for later use.

[0020] 2) The powder prepared in (l) was subjected to supercritical CO 2 For extraction, set the extraction temperature to 40°C, the extraction pressure to 25Mpa, and the extraction time to 100min. Seashore mallow flower hair oil is obtained after removing the moisture in the extracted oil.

[0021] 3) Carry out the first molecular distillation of seaside mallow flower crude oil obtained in (2), set the scraping film speed to 330r / min, cooling water temperature to 15°C, distillation temperature to 60°C, distillation pressure to 0.21kPa, and material flow rate to 10mL / min. Finally, the primary seaside mallow essential oil is obtained in the heavy phase collection tank.

[0022] 4) Carry out the second molecular distillation of the primary seaside mallow flower essential oil obt...

Embodiment 2

[0024] 1) Remove impurities from the picked seashore mallow flowers, put them in an oven at 50°C for 4 hours, take them out, and crush them into 45-mesh powder with crushing equipment for later use.

[0025] 2) The powder prepared in (l) was subjected to supercritical CO 2 For extraction, set the extraction temperature to 40°C, the extraction pressure to 30Mpa, and the extraction time to 120min. Seashore mallow flower hair oil is obtained after removing the moisture in the extracted oil.

[0026] 3) Carry out the first molecular distillation of seaside mallow flower crude oil obtained in (2), set the speed of scraping film to 260r / min, cooling water temperature to 20°C, distillation temperature to 55°C, distillation pressure to 0.11kPa, and material flow rate to 12mL / min. Finally, the primary seaside mallow essential oil is obtained in the heavy phase collection tank.

[0027] 4) Carry out the second molecular distillation of the primary seaside mallow flower essential oil...

Abstract

The invention discloses a method for carrying out supercritical CO2 extraction on kosteletzkya virginica L. flower essential oil. The kosteletzkya virginica L. flower essential oil is collected by adopting the methods of drying and grinding, supercritical CO2 extraction and two-time molecular distillation. By carrying out supercritical CO2 extraction on kosteletzkya virginica L. flower essential oil, the method is simple, is easy to operate and has the advantages of low cost, high extraction efficiency and no organic solvent residues.

Description

technical field [0001] The invention belongs to the field of biotechnology, in particular to a supercritical CO 2 Method for extracting seaside mallow essential oil. Background technique [0002] seaside mallow ( Kosteletzkyavginica L.) is a perennial perennial plant of Malvaceae, which is naturally distributed in the salt marsh coastal zone from Delaware to Texas along the eastern coast of the United States. Seashore mallow was introduced from the United States by Professor Admiration of Nanjing University in 1993, and has been widely promoted and planted in coastal areas of my country. Existing studies have shown that the whole plant of seaside mallow is rich in polysaccharides, saponins, flavonoids and other compounds, and has good biological activities such as anti-inflammatory, anti-tumor, lowering blood uric acid, anti-oxidative aging, and improving body immunity. At present, the development and utilization of seaside mallow mainly focus on the extraction of active ...
