Embodiment 1

[0024] A method for extracting essential oil from Chongqing Fengjie Yunyan 87 flower buds as raw materials, which is obtained by the following steps: adding distilled water to the crushed Chongqing Fengjie Yunyan 87 flower buds at a material-to-liquid ratio of 1:15 to 1:25; Add cellulase at 5% to 7% of the total mass, add sodium chloride at 10% to 14% of the total mass, ultrasonically treat for 10 to 25 minutes, and then use steam distillation for 4 hours. After cooling, open the lower piston of the separator to make the water slowly flow out. Collect the oil layer with a pipette, rinse the extractor three times with dichloromethane, combine the washing liquid with the oil layer, add anhydrous sodium sulfate overnight, remove the water, and rotate it at low temperature to remove the dichloromethane to obtain tobacco bud essential oil.

[0025] Through a five-level single factor test, the effects of four factors, namely sodium chloride concentration A, cellulase addition amount...

Embodiment 2

[0034] A method for extracting essential oil from Chongqing Fengjie Yunyan 87 flower buds, which is obtained by the following steps:

[0035] Add distilled water to crushed Chongqing Fengjie Yunyan 87 flower buds at a material-liquid ratio of 1:20, add cellulase according to 6% of the mass of tobacco flower buds, add sodium chloride according to 10% of the total mass, ultrasonically treat for 15 minutes, and then use Steam distillation for 4 hours, after cooling, open the lower piston of the separator to let the water flow out slowly. Collect the oil layer with a pipette, rinse the extractor three times with dichloromethane, combine the washing liquid with the oil layer, add anhydrous sodium sulfate overnight, remove the water, and rotate it at low temperature to remove the dichloromethane to obtain tobacco bud essential oil.

Embodiment 3

[0036] Application test: Antioxidative study of Chongqing Fengjie Yunyan 87 tobacco flower buds

[0037] 1) Determination of OH free radical scavenging rate of tobacco flower bud essential oil:

[0038] Tobacco flower bud essential oil and BHT solution with concentrations of 0.5, 1.0, 1.5, and 2.0 mg / mL were respectively prepared with 50% absolute ethanol as sample solutions (BHT was a positive control). Take 0.5mL of sample solution, add 50μL Tween 80, 1mL PBS buffer solution (pH=7.4), 1mL o-phenanthroline solution with a concentration of 7.5mmol / L, 1mL ferrous sulfate solution with a concentration of 3.25mmol / L, 2mL The hydrogen peroxide with a concentration of 1.5% was mixed thoroughly and placed at 37°C for 1 hour, and the absorbance A was measured at 536nm. The control group replaced each sample with distilled water, repeated the above operation, and measured the absorbance A at 536nm 1 , the blank group replaced o-phenanthroline, ferrous sulfate solution and hydrogen p...

Abstract

The invention discloses a process using Chongqing Fengjie Yunyan 87 flower buds as raw materials to extract essential oil and application of the essential oil. The process includes: adding distilled water into smashed Chongqing Fengjie Yunyan 87 flower buds according to the material-liquid ratio of 1:10-1:30, adding cellulase accounting for 2-10% of the weight of the tobacco flower buds, adding sodium chloride accounting for 5-25% of total weight, performing ultrasonic treatment for 10-40 minutes, and distilling with steam for 2-6 hours to prepare the flower bud essential oil. The flower bud essential oil prepared by the process has the advantages that the essential oil is capable of well eliminating OH free radicals and O2- free radicals and is a good antioxidant substance; meanwhile, the essential oil has certain antibacterial activity against escherichia coli, bacillus subtilis and paenibacillus polymyxa and is a good antibacterial agent. The Chongqing Fengjie Yunyan 87 flower bud essential oil prepared by the process can be used as an antioxidant agent and the antibacterial agent.

Description

technical field [0001] The invention belongs to the technical field of tobacco leaf products, in particular to a process for extracting essential oil from Chongqing Fengjie Yunyan 87 flower buds and its application as an antioxidant and antibacterial agent Background technique [0002] For plant essential oils, there are too many studies at home and abroad. Ling Yuzhao studied the steam distillation method to extract essential oils from citrus peels, and found that this method not only reduces energy consumption, but also has the advantages of simple installation and operation, saving reagents, and reducing pollution. Wang Hong et al. use CO 2 As an extractant to extract cocklebur seed oil, and compared with the material extracted by steam distillation, it is found that this method can not completely replace steam distillation. Vian et al. used microwave-assisted water diffusion gravity method to extract peppermint essential oil. The method has the advantages of rapidity,...
