Abstract

The invention discloses a method for extracting chrysanthemum essential oil and the extracted essential oil, and aims at solving the problem that the Hangzhou white chrysanthemum is processed by the way of drying in the sun or stoving in the prior art, and water soluble effective components are simply dissolved by water, so that many functional components have not been well utilized, resulting in a tremendous waste. The method for extracting the chrysanthemum essential oil comprises the following steps: pretreatment, ultrasonic treatment, Soxhlet backflow extraction, concentration and water vapor distillation. The extraction method of the invention has the characteristics of simpleness, practicality, low cost and high extraction rate, and can meet the need of large-scale and factory production of chrysanthemum essential oil, especially the need of chrysanthemum essential oil extraction. The invention can change the current extensive use of chrysanthemum, realize the deep processing of chrysanthemum, effectively use functional components of Hangzhou white chrysanthemum, and increase the economic added value, and has broad market prospect.

Description

technical field [0001] The invention relates to the field of essential oil extraction, in particular to a method for extracting chrysanthemum essential oil and the extracted essential oil.
