| Usage | absorption, bathing, indoor fragrance, massage and many other uses, can be used to cold or boiling water plus a few drops to treat Head Pain of the deviation of Head Pain, a warm towel, will eliminate the spirit of fatigue, and the evening of a Osmanthus bath helps to treat Sleep Initiation and Maintenance Disorders. |

| Use | as a food spice, widely used in osmanthus fragrance of various types of food flavor |
| production method | is distributed in Guizhou, Guangxi, Zhejiang, Fujian, jiangsu and other places of osmanthus fragrans flowers as raw material, at room temperature per kilogram of flower with 3L of petroleum ether in the drum extractor (6r/min) extraction of 90min. And petroleum ether washing 2 times, each time 20min. The leaching solution was distilled at atmospheric pressure to recover petroleum ether, and then distilled under reduced pressure at 40 ℃ and 80kPa to further recover petroleum ether to obtain crude jasmine extract. To the crude extract, 5% absolute ethanol was added, and the mixture was stirred and dissolved by heating. And 55 ℃, 92. 2kpa under reduced pressure distillation, as far as possible to remove ethanol-petroleum ether azeotrope, that is, jasmine extract yield of about 1.1% ~ 1.7%. A certain amount of petroleum ether and essential oil can also be recovered by direct distillation of flower residue with steam. |
