Essential oils (EOs) are a complex element consisting of dozens to hundreds of compounds different. The essential characteristics of essential oils are governed by the main components of essential oils including oxygen monoterpen, hydrocarbon monoterpene, oxygen sesquiterpene, carbonylic compound, phenol, fatty acids and esters, which determine the primary aroma of essential oil. Kaffir lime EOs (Citrus hystrix DC; Rutaceae) is increasingly being used as a flavoring in perfume, cosmetic industries and food. Therefore, the purpose of this study is to extract essential oils from Kaffir lime to determine the components that create this fragrance. Kaffir lime EOs is obtained from 100g of fresh citrus peels of Citrus hystrix DC by microwave extraction method in 60 minutes and 450W power. The quality of Kaffir lime peel oil is assessed based on the chromatography of the compound present by the gas chromatography–mass spectrometry (GC-MS). Shell analysis led to the identification of twenty-six compounds that make up 100% of the essential oil and yield is 6%. The main compounds in kaffir lime shells such as β-pinene (45.206%), α-pinene (2.365%), D-limonene (18.358%), citronellal (17.745%), terpinen-4-ol (4.9964%).
