加南加油具有很高的经济价值，可用作香料和食品香精。采用水蒸气蒸馏法和有机溶剂萃取法从香加兰（Cananga odorata Hook.）文件et Thomson，forma macrophylla.氯仿和己烷被用作具有不同极性的溶剂。挥发油及其分组化合物（倍半萜，倍半萜烃和HOC）的产率作为时间的函数进行了研究。HOC由含氧单萜和其它轻含氧化合物组成，而HOC包括含氧倍半萜和其它重含氧化合物。用氯仿（8 h）、己烷（8 h）和水蒸气蒸馏（16 h）分别获得5.1、3.8和2.5%干物质的油产率。分离速率符合一级动力学方程。水蒸气蒸馏法提取率最低，正己烷提取法次之，氯仿提取法最好。通过气相色谱-质谱联用分析油的组成。水蒸气蒸馏油和氯仿油具有相似的组成，具有高含量的含氧化合物（61.7%和58.3%），而己烷油富含倍半萜烃（66.5%）。
Cananga oil has high economical value because of its utilisation as fragrance and food flavour. In the present work, the oil was isolated by steam distillation and organic solvent extraction from dry mature flowers of Cananga odorata Hook. fil. et Thomson, forma macrophylla. Chloroform and hexane were used as solvents with different polarities. The yield of volatile oil and its grouped compounds (LOC, sesquiterpenes hydrocarbons and HOC) was investigated as a function of time. LOC consists of oxygenated monoterpenes and other light oxygenated compounds whereas HOC comprises oxygenated sesquiterpenes and other heavy oxygenated compounds. The oil yields of 5.1, 3.8 and 2.5 % dry matter were obtained with chloroform (8 h), hexane (8 h) and steam distillation (16 h), respectively. The isolation rate was described by a first-order kinetics equation. The rate was lowest with steam distillation, intermediate with hexane extraction and best with chloroform extraction. The oil composition was analyzed by gas chromatography coupled to mass spectrometry. The steam-distilled oil and chloroform oil had a similar composition, with a high content of oxygenated compounds (61.7% and 58.3%), while hexane oil was rich in sesquiterpenes hydrocarbons (66.5%).
