Embodiment 1

[0013] Agarwood is crushed into a coarse powder of 80 mesh sieve, 500g is taken, and a compound enzyme (mixed enzyme of cellulase, amylase and protease in a weight ratio of 0.6:0.2:0.2) equivalent to 1% of the agarwood coarse powder is sprayed on it. , wrapped and sealed with a film, fermented at 30°C for 1 day, dried the fermented raw materials at 60°C, added 10 times of distilled water, placed in a microwave extractor with a power of 200W for 90min, and centrifuged to obtain the extract The liquid was extracted, then extracted three times with cyclohexane, the filtrates were combined, dried over anhydrous sodium sulfate, and concentrated under reduced pressure at 50°C to obtain 4.6 g of agarwood volatile oil with a yield of 0.92%.

Embodiment 2

[0015] Agarwood is crushed into a coarse powder of 80 mesh sieve, 500g is taken, and a compound enzyme (mixed enzyme of cellulase, amylase and protease in a weight ratio of 0.6:0.2:0.2) equivalent to 1.5% of the agarwood coarse powder is sprayed on it. above, film wrapped and sealed, and fermented at 45°C for 3 days, and the fermented raw materials were dried at 60°C, added with 8 times of distilled water, extracted in a microwave extractor with a power of 400W for 30min, and centrifuged to obtain the extract The liquid was extracted, then extracted three times with ether, the filtrates were combined, dried over anhydrous sodium sulfate, and concentrated under reduced pressure at 20°C to obtain 5.3 g of agarwood volatile oil with a yield of 1.06%.

Embodiment 3

[0017] Agarwood is crushed into a coarse powder of 80 mesh sieve, 500g is taken, and a compound enzyme (mixed enzyme of cellulase, amylase and protease in a weight ratio of 0.6:0.2:0.2) equivalent to 2% of the agarwood coarse powder is sprayed on it. above, film wrapped and sealed, and fermented at 40°C for 5 days, and the fermented raw materials were dried at 60°C, added with 5 times of distilled water, placed in a microwave extractor with a power of 600W for 60min, centrifuged, and extracted The liquid was extracted, then extracted twice with n-hexane, the filtrates were combined, dried over anhydrous sodium sulfate, and concentrated under reduced pressure at 50°C to obtain 4.9 g of agarwood volatile oil with a yield of 0.98%.

Abstract

The invention relates to an extraction method of volatile oil of agilawood, and in particular relates to a method for extracting volatile oil of agilawood with microwave assisting. The method is characterized by comprising the following steps: crushing agilawood into coarse powder sieved with 80-mesh sieve; fermenting with compound enzyme; drying the fermented raw materials under 60 DEG C; adding distilled water with the amount being 5 to 10 times that of the raw materials; adding into a microwave extractor to extract; centrifuging to obtain leaching liquor; extracting with an organic solvent for once to three times; mixing the filtrates; drying with anhydrous sodium sulfate; and then performing pressure-reduced concentration under 30 to 50 DEG C to obtain the volatile oil of agilawood. The method is simple to operate, obvious in technical effect, and low in cost; the extracted volatile oil is high in yield and high in quality and applicable to industrial production.

Description

technical field [0001] The invention relates to a method for extracting agarwood volatile oil, in particular to a microwave-assisted extraction method for agarwood volatile oil, which belongs to the technical field of vegetable oil extraction. Background technique [0002] Agarwood is the resinous wood of Agarwood, a plant in the family Daphneaceae. It tastes pungent, bitter, and warm. It returns to the spleen, stomach, and kidney channels. Hiccups, kidney deficiency, Qi inversion and dyspnea embolism. Agarwood volatile oil is the main component of the volatile medicinal effect of agarwood, which contains sesquiterpene components such as agarwood helicol, white wood acid, white wood aldehyde, and aromatic components such as benzyl acetone and p-methoxybenzyl acetone. Pharmacological studies have found that some sesquiterpene components in the volatile oil of agarwood, agarwood helixol, have chlorpromazine-like stabilizing effects, and agaric acid has certain hypnotic anesth...
