Embodiment

[0014] Example, an extraction method of agarwood essential oil, first cut down the agarwood incense tree, remove the agarwood, and carve into agarwood flakes; then crush the agarwood flakes into agarwood powder with a 40-mesh sieve; then add the agarwood powder to the extraction kettle with n-butane , using subcritical fluid extraction technology to directly extract agarwood essential oil, the extraction conditions: extraction time is 1 hour, analysis temperature is 60°C, extraction temperature is 50°C, extraction pressure is 0.4-0.5MPa; then the first extraction of agarwood essential oil The residue is added to the extraction kettle with 95% ethanol for the second extraction, and the extraction condition is as follows: the agarwood essential oil is extracted according to the same extraction condition as the first extraction of the agarwood essential oil.

[0015] One of the applications of extracting agarwood essential oil is to extract agarwood essential oil with ethanol, add...

Abstract

The invention relates to an extraction method of agilawood essential oil, which comprises the following steps: firstly, cutting down aquilaria sinensis trees, removing white wood and carving into agilawood slices; grinding the agilawood slices into agilawood powder with specification of 40 meshes; then adding the agilawood powder into an extraction kettle by normal butane and directly extracting agilawood essential oil by adopting a subcritical fluid extraction technology under the extraction conditions that extraction time is 0.5 to 1.5 hours, analysis temperature is 60 DEG C, extraction temperature is 50 DEG C and extraction pressure is 0.4 Mpa to 0.5MPa; and then adding slags obtained after extracting the agilawood essential oil for the first time into the extraction kettle by 95 percent of ethanol to carry out extraction for the second time under the same extraction conditions in the process of extracting the agilawood essential oil for the first time. The invention aims to provide the extraction method and application of the agilawood essential oil.

Description

technical field [0001] The invention relates to an extraction method, in particular to an extraction method of agarwood essential oil and the application of agarwood essential oil. Background technique [0002] Agarwood has the effects of promoting qi and relieving pain, warming the middle and relieving vomiting, nourishing qi and relieving asthma, nourishing the heart and calming the nerves, dredging the meridian and lowering qi, and has significant curative effects in the treatment and prevention of coronary heart disease, angina pectoris, myocardial ischemia, arrhythmia and other diseases. However, the traditional process only uses one extraction to extract agarwood essential oil, and the available agarwood oil is limited. Agarwood oil is very precious, how to obtain more agarwood oil has become the goal that everyone in this industry is vying for. Contents of the invention [0003] The purpose of the present invention is to provide a method for extracting agarwood ess...
