Embodiment 1

[0018] Accurately weigh 10 kg of washed and dried osmanthus samples, add 30 L of food-grade petroleum ether, extract on a shaking table for 1 hour, and extract twice. Collect the filtrate, distill under reduced pressure to recover petroleum ether, add 100 times of absolute ethanol to the remaining filtrate, reflux at 50°C for 1 hour, collect the liquid at -20°C overnight, freeze and suction filter, evaporate the solvent, and obtain a bright yellow liquid, which is Osmanthus essential oil.

[0019] After detection and analysis, the quality of the obtained osmanthus essential oil is: clear brown-yellow flowing liquid, with the aroma of natural osmanthus; ) was not detected, the arsenic content (As) was not detected, and the characteristic components were 4.0% dihydro-β-ionone and 1.0% ionone.

Embodiment 2

[0021] Accurately weigh 10 kg of washed and dried osmanthus samples, add to 30 L of water, condense and reflux for extraction for 6 hours, and extract twice. Collect the filtrate, extract it with food-grade petroleum ether, and dry it overnight with anhydrous sodium sulfate to obtain a bright yellow liquid, which is osmanthus essential oil.

[0022] After detection and analysis, the quality of the obtained osmanthus essential oil is: clear brown yellow flowing liquid, with the aroma of natural osmanthus; relative density (25 / 25°C) 0.900, refractive index (20°C) 1.440, ester value 25, heavy metal (calculated as Pb) ) was not detected, the arsenic content (As) was not detected, and the characteristic components were 2.5% dihydro-β-ionone and 0.5% ionone.

Embodiment 3

[0024] Accurately weigh 10 kg of washed and dried osmanthus samples, add 30 ml of an aqueous solution containing β-glucosidase, control the pH value at 5.0, and perform enzymatic hydrolysis at 50°C for two hours. After washing with water, dry, add 400 times absolute ethanol, condense and reflux at 55°C for 1 hour, collect the liquid at -20°C overnight, freeze and suction filter, evaporate the solvent, and obtain a bright yellow liquid, which is osmanthus essential oil.

[0025] After detection and analysis, the quality of the obtained osmanthus essential oil is: clear brown yellow flowing liquid, with the aroma of natural osmanthus; ) was not detected, the arsenic content (As) was not detected, and the characteristic components were 0.5% dihydro-β-ionone and 0.06% ionone.

[0026] Therefore, the quality requirements of the osmanthus essential oil used in this example are: clear brownish-yellow flowing liquid with natural osmanthus fragrance; relative density (25 / 25°C) 0.900-0....

Abstract

The invention discloses an application of a sweet osmanthus essential oil in resisting a decayed tooth. The sweet osmanthus essential oil adopts a sweet osmanthus essential oil as an effective component and is assisted by other auxiliary materials, the addition amount of the sweet osmanthus essential oil is 0.25%-6% by mass, and preferably, the range is 0.25%-4%; the sweet osmanthus essential oil has the quality requirements that the sweet osmanthus essential oil is a clear brown-yellow flowing liquid and has a natural sweet osmanthus aroma, the relative density (25 / 25 DEG C) is 0.900-0.986, the refractive index (20 DEG C) is 1.440-1.496, the ester value is more than or equal to 25, the content of a heavy metal (calculated according to Pb) is less than or equal to 40 mg / kg, the content of arsenic (As) is less than or equal to 3 mg / kg, the content of a characteristic component dihydro-beta-ionone is more than or equal to 0.5%, and the content of a characteristic component ionone is more than or equal to 0.06%. The sweet osmanthus essential oil can be developed as a decayed tooth resisting product, has good treatment effect on the decayed tooth, moreover, has significant sweet osmanthus fragrance, has no any toxic side effects, and easily realizes industrialized production. The prominent problems that a conventional decayed tooth resisting product has no obvious bacteriostatic effect or has side effects or is easy to volatilize are solved, and popularization, application, economic benefits and social benefits are quite remarkable.

Description

technical field [0001] The invention relates to the application of osmanthus essential oil, especially the application of osmanthus essential oil in anti-caries. Background technique [0002] Dental caries is a common and frequently-occurring disease in the oral cavity, and it is the main cause of toothache. The World Health Organization has listed dental caries, tumors, and cardiovascular diseases as three key human diseases. Dental caries is that after sugary food enters the oral cavity, it is fermented by cariogenic bacteria in the dental plaque to produce acid. These acidic substances soften the tooth tissue and accelerate the dissolution of calcium, resulting in dental caries. The occurrence of dental caries requires the following four conditions: ① cariogenic bacteria; ② the material basis (sugar) for bacteria to carry out metabolic activities; ③ the ecological environment for bacteria to metabolize and cause disease on the tooth surface; ④ susceptible teeth. These f...
