Problems solved by technology

At present, most of the separation and analysis of plant branches, leaves and fruit essential oils use steam distillation. This method is relatively stable, but it also has certain shortcomings.
In the article "Study on the Extraction of Chemical Components of Kaempfera Volatile Oil by Supercritical CO2 Fluid Extraction and Steam Distillation", a comparative experiment between steam distillation and supercritical CO2 extraction was carried out. The results show that the steam distillation extraction process takes a long time and the temperature is high. , The system is open, the process is easy to cause thermal instability and the destruction and volatilization loss of easily oxidized components, and has a destructive effect on some components

Abstract

The invention aims to provide a method for extracting yellow cinnamon leaf essential oil by combination of steam distillation and supercritical CO2 extraction. The method comprises the following steps: distilling yellow cinnamon leaves with steam to remove impurity components dissolved in an aqueous phase, drying the extracted yellow cinnamon leaves, feeding the dried yellow cinnamon leaves into a supercritical extraction device, and extracting the yellow cinnamon leaf essential oil from the yellow cinnamon leaves in the presence of ethanol serving as an entrainer. According to the method, the yield of the yellow cinnamon leaf essential oil can be obviously improved and a high-quality essential oil product is obtained.

Description

technical field [0001] The invention belongs to an essential oil extraction method, in particular to an extraction method of camphor leaf essential oil. Background technique [0002] Essential oil is the general term for certain volatile oily components in plants, which have more biomedical activities, such as anti-inflammatory, analgesic, calming, insect repelling, expectorant, cough, wind, sweating, sterilization, skin care, etc. It is of great significance to improve the normal physiological activities of the human body, promote and protect the immune system. Studies have shown that different essential oils have beneficial effects on endocrine, metabolism, urinary system, sexually transmitted diseases, immune system, gynecological diseases, muscle and bone diseases, skin diseases, nervous system and mental diseases, eye, nose, oral cavity, dental diseases, respiratory system diseases, Diseases of the blood circulation system and diseases of the digestive system have good...
