Abstract

The invention discloses an extraction method of agilawood essential oil. Ethanol is selected as an entrainer for supercritical carbon dioxide extraction of the agilawood essential oil, and a supercritical carbon dioxide extraction technology is combined with a rectification technology, so that the solubility and the dissolution range of an extracting solvent are effectively improved, and the extraction rate of the agilawood essential oil is increased. Therefore, the obtained agilawood essential oil is even and clear in color and luster, and strong in smell.

Description

technical field [0001] The invention belongs to an essential oil extraction method, in particular to a method for extracting agarwood essential oil by combining supercritical CO2 extraction and rectification technology. Background technique [0002] Agarwood Aquilaria sinensis (Lour)Gilg is resinous wood, which is listed in the "Chinese Pharmacopoeia", and is a commonly used medicine for regulating Qi in clinical practice. Its taste is pungent, bitter, and warm in nature, and it belongs to the spleen, stomach, and kidney channels. Indications of chest and abdomen distension and pain, stomach cold, vomiting and hiccups, kidney deficiency and dyspnea. Agarwood contains a high amount of volatile oil and has a strong aroma. It is the main component of the volatile medicinal effect of Agarwood. The amount of volatile oil contained in it is directly related to the quality of the medicinal material. [0003] Steam distillation is a common method to extract the volatile oil of ag...
