Problems solved by technology

Agarwood is the white wood that remains connected with agarwood after removing the balsam from the agarwood. It contains a very small amount of balsam, so the price of agarwood is expensive
[0007] The essential oil of agarwood is the volatile oil extract of agarwood. There are many methods for extracting agarwood essential oil, including steam distillation, supercritical extraction, solvent method and compound enzyme fermentation extraction method, etc., but these extraction methods have little effect on the extraction efficiency of agarwood. Not very high, easy to cause waste of raw materials

Embodiment 1

[0024] A method for extracting agarwood essential oil, comprising the following steps:

[0025] (1) raw material processing: crushing agarwood into agarwood powder, and spraying the agarwood powder so that the water content of the agarwood powder reaches 75%;

[0026] (2) The first microwave extraction: put the agarwood powder processed in step (1) into a physical bottle for solvent-free microwave extraction for the first microwave extraction, and the first microwave extraction method is intermittent The specific process of extraction is as follows: microwave output power is 400W, microwave extraction is 5 minutes, and the interval is 5 minutes, which is an extraction cycle, and this extraction cycle is repeated 6 times.

[0027] (3) The product obtained in step (2) was left to stand for 2 hours, and the oil layer was removed to obtain the first agarwood essential oil;

[0028] (4) The second microwave extraction: the agarwood powder after the first microwave extraction is pu...

Embodiment 2

[0034] A method for extracting agarwood essential oil, comprising the following steps:

[0035] (1) Raw material processing: crushing agarwood into agarwood powder, and spraying the agarwood powder so that the water content of the agarwood powder reaches 80%;

[0036] (2) The first microwave extraction: put the agarwood powder treated in step (1) into a physical bottle for solvent-free microwave extraction for the first microwave extraction, wherein the microwave output power is 200W, and the microwave extraction is 10min, and 10min is an extraction cycle, and this extraction cycle is repeated 6 times.

[0037] (3) The product obtained in step (2) was left to stand for 2 hours, and the oil layer was removed to obtain the first agarwood essential oil;

[0038] (4) The second microwave extraction: the agarwood powder after the first microwave extraction is put into an ethanol solution with a mass concentration of 90% and soaked for 3 to 5 hours. After the soaking is completed, ...

Abstract

The invention discloses an agilawood essential oil extraction method. According to the technical scheme, agilawood is extracted according to a microwave extraction method, and microwave extraction refers to that the extraction efficiency of a solvent is enhanced by using microwaves, and certain organic components in a solid or a semi-solid test sample are effectively separated from substrate substances; the microwave heating time is short, and thermal unstable substances can be prevented from decomposition reactions; due to microwave extraction, rapidness and energy conservation can be achieved, the solvent can be saved, the pollution is low, and multiple test samples can be simultaneously treated; according to the technical scheme, two times of microwave extraction are implemented, so that volatile oil components in the agilawood can be well extracted, waste of raw materials is reduced, and the extraction efficiency can be improved.

Description

technical field [0001] The technical solution belongs to the technical field of natural plant essential oil extraction, and in particular relates to an extraction method of agarwood essential oil. Background technique [0002] Essential oil is the general term for certain volatile oily components in plants. It has more biomedical activities, such as anti-inflammatory, analgesic, soothing, insect repellent, sterilization, skin care, sweating, etc., which can improve the normal physiological activities of the human body. It is of great significance to promote and protect the immune system. Studies have shown that different essential oils have good curative effects on endocrine, metabolism, gynecological diseases, nervous system and digestive system diseases. [0003] Agarwood is a resinous wood of Daphne chinensis, white wood, which is included in the "Chinese Pharmacopoeia", and is a commonly used qi-relieving medicine in clinical practice. Its taste is pungent, bitter, and...
