Abstract

The invention discloses a method for extracting chrysanthemum indicum essential oil in an ultrasonic-assisted solvent-free microwave extraction manner, belongs to the technical field of chemical engineering. The method for extracting chrysanthemum indicum essential oil comprises the following steps: refrigerating, drying and crushing fresh chrysanthemum indicum, performing spraying treatment for keeping a certain humidity; performing pretreatment on crushed chrysanthemum indicum in an ultrasonic cell crusher; transferring the chrysanthemum indicum sample subjected to ultrasonic disruption into a solvent-free microwave-assisted extraction material bottle, extracting, cooling and leaving to stand to obtain the chrysanthemum indicum essential oil. According to the method for extracting chrysanthemum indicum essential oil in the ultrasonic-assisted solvent-free microwave extraction manner, the defects of a conventional extraction method are overcome, the extraction time is short, the temperature is low, and aroma components are prevented from being damaged by heat to the greatest extent; and besides, the extraction ratio and the quality of the obtained chrysanthemum indicum essential oil are all improved, so that the method is obviously superior to other conventional methods.

Description

technical field [0001] The invention relates to the technical field of extracting natural plant essential oils, in particular to a method for ultrasonic-assisted solvent-free microwave extraction of wild chrysanthemum essential oils. Background technique [0002] Wild chrysanthemum has vast resources and is a broad-spectrum antibiotic in Chinese herbal medicine. Its flowers have excellent medicinal health care effects and high drinking value. Studies have shown that wild chrysanthemum essential oil is rich in monoterpenes and sesquiterpenoids, and has various biological activities such as antibacterial, antiviral, anti-inflammatory and immune, and has broad development prospects. At the same time, wild chrysanthemum essential oil has a strong aroma and is widely used in the fragrance industry, and can also be used in cigarettes, cosmetics and other fields. Due to the backward extraction process at present, the extraction yield and purity of essential oils are low, the aroma...
