Problems solved by technology

However, the disadvantage of the steam distillation method is that the extraction temperature is high and the time-consuming is long, and it is easy to decompose the chemical components in the volatile oil that are unstable to humidity and heat and easy to oxidize.

Embodiment 1

[0015] Use dried Senecio sagenifolia as raw material, pulverize, pass through a 20-mesh sieve, take 1kg of powder, add 2% of raw material biological enzyme (the mass ratio of cellulase to hemicellulase is 2:1, and its activity is 40u / mg), mix well, spray the same amount of acetic acid / sodium acetate buffer solution with a pH of 4.5 as the raw material, wrap it in film, and ferment at 50°C for 3 days; add 3 times the 70% ethanol solution to the fermented raw material, use Double-frequency ultrasonic extraction, ultrasonic frequency 20KHz, 40KHz, power 500W, continuous extraction at 60 ° C for 2 hours, filtered, the filtrate was concentrated in a rotary evaporator to no alcohol, extracted twice with petroleum ether, combined filtrate, anhydrous sulfuric acid Sodium drying, dehydration, and concentration under reduced pressure yielded 19.1 mL of light yellow Senecio volatile oil.

Embodiment 2

[0017] Use dried Senecio sagenifolia as raw material, crush it, pass through a 20-mesh sieve, take 1kg of powder, add 2.5% of raw material biological enzyme (the mass ratio of cellulase to hemicellulase is 2:1, and its activity is 60u / mg), mix evenly, spray the same amount of acetic acid / sodium acetate buffer solution with a pH of 5.0 as the raw material, wrap it in film, and ferment at 60°C for 5 days; add 5 times the 75% ethanol solution to the fermented raw material, use Double-frequency ultrasonic extraction, ultrasonic frequency 20KHz, 40KHz, power 600W, continuous extraction at 70 ° C for 3 hours, filtered, the filtrate was concentrated in a rotary evaporator until there was no alcohol smell, extracted 3 times with ether, combined filtrate, anhydrous sodium sulfate Dry and dehydrate, and concentrate under reduced pressure to obtain 22.4 mL of light yellow Senecio volatile oil.

Embodiment 3

[0019] Use the dry Senecio shuanghua as raw material, crush it, pass through a 20-mesh sieve, take 1kg of powder, add 3% of the raw material biological enzyme (the mass ratio of cellulase to hemicellulase is 2:1, and its activity is 50u / mg), mix well, spray the same amount of acetic acid / sodium acetate buffer solution with a pH of 5.5 as the raw material, wrap it in film, and ferment at 55°C for 4 days; add 4 times the 80% ethanol solution to the fermented raw material, and use Double-frequency ultrasonic extraction, ultrasonic frequency 20KHz, 40KHz, power 600W, continuous extraction at 65 ° C for 3 hours, filtered, the filtrate was concentrated in a rotary evaporator until no alcohol smell, extracted 3 times with cyclohexane, combined filtrate, anhydrous Dry and dehydrate with sodium sulfate, and concentrate under reduced pressure to obtain 18.3 mL of light yellow volatile oil of Senecio bisflora.

Abstract

The invention discloses a method for extracting senecio dianthus volatile oil. The method comprises the following steps: crushing dried senecio dianthus as a raw material, screening by using a 20-mesh screen, fermenting for 3-5 days by using biological enzyme, adding the fermented raw material into 3-5 times of 70-80% ethanol solution, extracting by using double-frequency ultrasonic wave, continuously extracting for 2-3 hours at 60-70 DEG C, filtering, concentrating the filtrate in a rotation evaporator till no alcohol odor is completed eliminated, extracting for 2-3 times by using an organic solvent, combining the filtrate, drying to dehydrate by using anhydrous sodium sulfate, and performing vacuum concentration, thereby obtaining the senecio dianthus volatile oil, wherein the ultrasonic wave frequency is 20KHz and 40KHz, and the power is 500-600W. According to the method, biological enzyme fermentation pretreatment and a double-frequency ultrasonic method are combined to extract the senecio dianthus volatile oil, the process is simple, the extraction time is short, the energy consumption is small, the yield of the volatile oil is remarkably higher than that of a conventional extraction method, and the method is applicable to industrialization production.

Description

technical field [0001] The invention relates to a method for extracting the volatile oil of Senecio sagelicense, in particular to a method for extracting the volatile oil of Senecio shuanghua assisted by biological enzyme fermentation with dual-frequency ultrasound. Background technique [0002] The Tibetan medicinal plant Senecio biflora is a perennial herb of the genus Senecio in the Asteraceae family, which has special effects of clearing away heat and detoxifying. In recent years, some Tibetan compatriots have used Shuanghua Senecio as a beauty treatment, and the effect is good. There are many species of plants in the genus Senecio, and the literature shows that the current research on them mainly focuses on sesquiterpenes and water-soluble alkaloids, as well as the chemical components of their volatile oils, but there are few studies on the extraction methods of their volatile oils. The essential oil of Senecio double flower contains more chemical components, mainly mo...
