Embodiment 1

[0019] A kind of wax plum essential oil extraction process, it comprises the following process steps:

[0020] A, collection: collect the wintersweet flower that just opened as raw material;

[0021] B. Transportation and storage: The wintersweet flowers collected in step A are sealed and transported at low temperature to a cold storage for storage at no more than minus 15 degrees Celsius, and set aside;

[0022] C, pretreatment: immerse 1 kilogram of wintersweet flowers preserved in step B in 10 liters of ethanol with a mass concentration of 62%, stir at 50° C. for 3 hours, and cool;

[0023] D, pulverization: the wintersweet petals pretreated in step C are placed in a high-speed pulverizer to pulverize, and the pulverized particle size is between 180 mesh and 200 mesh;

[0024] E, microwave extraction: place the petals of the wax plum flower pulverized in step D in 3 liters of ethanol with a mass concentration of 73% for microwave extraction, set the microwave output power ...

Embodiment 2

[0028] A kind of wax plum essential oil extraction process, it comprises the following process steps:

[0029] A. Collection: Collect the newly opened Yanling wintersweet flowers as raw materials. The flowering period of Yanling wintersweet is generally from the beginning of the twelfth lunar month to the beginning of the second lunar month of the next year. Among them, the wintersweet flowers whose flowering period is from the middle of the wax month to the late first month of the next lunar calendar are the best. , you can collect the just-opened wintersweet flowers during this period of time;

[0030]B. Transportation and storage: The wintersweet flowers collected in step A are sealed and transported at low temperature to a cold storage for storage at no more than minus 15 degrees Celsius, and set aside;

[0031] C, pretreatment: soak 2 kilograms of the wintersweet flowers preserved in step B in 30 liters of ethanol with a mass concentration of 68%, stir at 55° C. for 2 hou...

Abstract

The invention belongs to the technical field of essential oil extraction, and in particular relates to an extraction process for a Chimonanthus fragrans essential oil. Aiming at the characteristics of Chimonanthus fragrans, the extraction process employs the processes of collecting, transporting and storing, pretreating, pulverizing, microwave extracting, steam extracting and purifying in a proper order, thus improving the extraction rate of the Chimonanthus fragrans essential oil. The Chimonanthus fragrans essential oil is sampled and measured by gas phase chromatography to obtain that the organic solvent residue is zero. The extraction process provided by the invention can employ large-sized extraction equipment to carry out large-scale extraction of the Chimonanthus fragrans essential oil, can realize industrial production, and fills the blank of the extraction of the Chimonanthus fragrans essential oil at home and abroad.

Description

technical field [0001] The invention belongs to the technical field of essential oil extraction, and in particular relates to a process for extracting waxy plum essential oil. Background technique [0002] Wintersweet ( Calycanthaceae ) plants are divided into 4 genera in the world, namely the genus Wintersweet ( Chimonanthus lindley ), Wintersweet ( Sinocalycanthus ), American Wintersweet ( Calycanthus. L ), Lepidoptera ( Idiospermum Blake ), 10 varieties, 4 variants. Among them, Wintersweet and Wintersweet are special products in China, American Wintersweet is distributed in North America, and Chair Tree is distributed in Australia. Among them, Wintersweet is the most widely distributed and most cultivated, and many scientific researchers at home and abroad have carried out various researches on it. The data show that there are 9 species and 1 variety in the genus Wintersweet, which are Wintersweet ( Chimonanthus Praecox ), Southwestern Wintersweet ( C. camp...
