Embodiment 1

[0016] Dried notopterygium in the sun and pulverized it, passed through a 20-mesh sieve, added cellulase with 1% of the raw material mass, mixed evenly, sprayed acetic acid / sodium acetate buffer solution with pH 4.0, and held it in a ball, wrapped and sealed with a film, and dried at 40 Ferment for 3 days at a temperature of ℃; add 5 times of 20% ethanol to the fermented raw materials, place in an ultrasonic-microwave extractor for extraction, control ultrasonic 600W, and microwave power 400W for continuous extraction for 2 hours, filter, and reduce the filtrate at 50 °C Concentrate under reduced pressure to obtain a concentrated solution; extract the concentrated solution with petroleum ether, dry over anhydrous sodium sulfate, concentrate under reduced pressure at 50°C to evaporate the organic solvent, and obtain notopterygium volatile oil with a yield of 2.6%.

Embodiment 2

[0018] Dried notopterygium and crushed, passed through a 20-mesh sieve, added cellulase with a mass of 1.5% of the raw material, mixed evenly, and sprayed with acetic acid / sodium acetate buffer solution with pH 4.5 until it could be held into a ball, wrapped and sealed with a film, and dried at 45 Ferment at ℃ for 5 days; add 6 times of 50% ethanol to the fermented raw material, put it in an ultrasonic-microwave extractor for extraction, control ultrasonic 600W, and microwave power 500W to extract continuously for 1.5h, filter, and store the filtrate at 30℃ Concentrate under reduced pressure to obtain a concentrated solution; extract the concentrated solution with ether, dry over anhydrous sodium sulfate, concentrate under reduced pressure at 50°C to evaporate the organic solvent, and obtain notopterygium volatile oil with a yield of 2.9%.

Embodiment 3

[0020] Dried notopterygium in the sun and pulverized, passed through a 20-mesh sieve, added cellulase with 2% raw material quality, mixed evenly, sprayed acetic acid / sodium acetate buffer solution with pH5. Ferment for 7 days at a temperature of ℃; add 7 times of 40% ethanol to the fermented raw materials, place in an ultrasonic-microwave extractor for extraction, control ultrasonic 600W, microwave power 600W for continuous extraction for 1 hour, filter, and reduce the filtrate at 40 ℃ Concentrate under reduced pressure to obtain a concentrated solution; extract the concentrated solution with petroleum ether, dry over anhydrous sodium sulfate, concentrate under reduced pressure at 50°C to evaporate the organic solvent, and obtain notopterygium volatile oil with a yield of 2.3%.

Abstract

The invention relates to a method for extracting notopterygium root volatile oil. The method is characterized by comprising the following steps: airing and grinding notopterygium root, allowing the notopterygium root to pass through a sieve with the granularity of 20 meshes, performing cellulase fermentation, adding 20-50% ethanol which is in an amount of 5-7 times that of the raw materials into the fermented raw materials, extracting in an ultrasonic-microwave extractor, filtering, performing vacuum concentration on the filtrate at the temperature of 30-50 DEG C, extracting the concentrated solution by using an organic solvent, drying by using anhydrous sodium sulfate, and performing vacuum concentration at the temperature of 50 DEG C to remove the organic solvent, thereby preparing the notopterygium root volatile oil. The method is easy to operate and obvious in technical effect, and damage to structures of the volatile oil components can be reduced.

Description

technical field [0001] The invention relates to a method for extracting notopterygium volatile oil, belonging to the technical field of vegetable oil extraction. Background technique [0002] Notopterygium is the dried rhizome of notopterygium or notopterygii of Umbelliferae, warm in nature, pungent and bitter in taste. It has the effects of relieving exterior cold, expelling wind and dampness, and relieving pain. It is mainly used to treat colds, headaches, rheumatic arthralgia, shoulder pain and other diseases. Notopterygium contains about 2%~3% volatile oil, which mainly contains hexanal, heptanal, heptane, α - pinene, β - pinene, α- Compositions such as arborvitene, octanoic acid, malebenyl acetate, thymol, piperonene and other components have a strong inhibitory effect on Brucella and Staphylococcus aureus, and have sedative, hypnotic, analgesic and anti-inflammatory effects . [0003] Volatile oils are usually unstable, easily denatured and invalidated, and choosi...
