The essential oils (EOs) was extracted from Persian lime (Citrus latifolia) peels collected in Hau Giang province, Vietnam. Volatile compositions of EOs obtained by three extraction methods of hydrodistillation (HD), steam distillation (SD) and microwave extraction (ME) were analyzed and compared. The volatile compounds in EOs were analyzed based on gas chromatography-mass spectrometry (GC-MS). An amount of 3 ml/g, 2.3 ml/g and 4 ml/g of EOs was obtained from HD, SD and ME with twenty-one compounds were identified, accounting for 99% -100% of the total oil content. Limonene, β-pinene, α-pinene, γ-Terpinene, α-citral, β-citral and Sabinene are the major compound in essential oil. However, there were qualitative and quantitative differences between oil samples obtained by the three extraction methods. The difference is probably due to the influence of different environmental factors and specific characteristics of each extraction method. The results of this study will provide information on the content and chemical composition of Lemon peels. C. latifolia and serve as a stepping stone for further research into the applications of the compound to cosmetic, food and pharmaceutical products.
