摘 要：桂花屬于木犀科、木犀屬植物，不僅有許多食用價值和藥用價值，而且還被廣范用于化工等行業。桂花精油為深黃色或棕色蠟狀半固體，具有甜清花香，能凈化空氣，有散寒祛風濕, 療牙痛,咳嗽,美容美白肌膚,排解體內毒素及通便等功效。本論文通過研究超臨CO2流體P-V-T原理、相平衡原理與模型的探討和計算，得出超臨界CO2萃取在香料萃取及桂花香料萃取中的優越性。課題還通過石油醚回流浸提及正交試驗探討了從銀桂中提取桂花精油的最佳工藝條件。回流溫度：75℃，回流時間：80分鐘，桂花與石油醚體積比：1：2，精油含量：1.5%。

The Study on the Technology of Extracting
Osmanthus Fragrance Spice
Abstract: Osmanthus, belong to Oleaceae Osmanthus, which extracts not only has many edible and medicinal value, but also wide used in chemical industry. Osmanthus Essential oil is a kind of wax for deep yellow or brown semi-solid, with clear sweet floral, slightly sweet and clear sense, having  effectiveness such as cold-dispelling rheumatism, toothache, cough, skin whitening beauty, troubleshooting, and purge toxins from the body. This article, back through the discussion and calculating of the supercritical CO2 P-V-T principles,the phase equilibrium and the models,coming to the superiority of extracting spices and the advantages of extracting Osmanthus fragrans. And the study back through the petroleum ether extraction reflowing and orthogonal test of extracting from the Osmanthus fragrans，extract the optimum conditions. Temperature of extraction 75℃，extracting time 80min，Osmanthus and petroleum ether volume ratio 1：2，Total extract content 1.5%.
