| 摘要: |
| 目的 对比鸡蛋花不同干燥方法对其挥发油成分的影响。方法 采用水蒸汽蒸馏法进行挥发油提取，并用气相色谱质谱联用技术对挥发油进行了分离和鉴定，采用面积归一化法确定各成分的相对百分含量。结果 挥发油提取率：鲜品0.15%、阴干0.05%、晒干0.02%。气相色谱鉴定出58种成分，最后确定28种，主要为橙花叔醇、金合欢醛、苯甲酸苄酯、水杨酸苯甲酯、苯甲酸香叶酯、橙花基芳樟醇异构体、α-异戊酸松油酯等。结论 鸡蛋花的干燥方法阴干优于晒干，既保存了挥发油的含量也降低了毒性成分。鸡蛋花挥发油易受日照、温度、放置时间的影响，因此加工过程中应严格按照规范操作。 |

| Abstract: |
| OBJECTIVE To evaluate the effects of different drying methods on the essential oil from Plumeria rubra L. var. actifolia Bailey. METHODS To extract the essential oil by steam distillation, separate and identify by GC-MS. The relative contents in percentage were calculated with area normalization method. RESULTS Essential oil extraction rates were 0.15%, 0.05% and 0.02% for fresh, drying in the shade and drying in the sun samples, respectively. In 58 substances, 28 were identified from Plumeria rubra L. var. actifolia Bailey, such as d-nerolidol, farnesol, benzyl benzoate, geranyl benzoate, neryl linalool isomer and α-terpinyl isovalerate. CONCLUSION The Plumeria rubra L. var. actifolia Bailey drying in the shade is better than drying in the sun. It is favorable to keep the content of the essential oil and reduce toxicity. The essential oil of Plumeria rubra L. var. actifolia Bailey is easily affected by sunshine, temperature and storage time. Standard operation is very important in production. |
