The volatile components of 20 mango cultivars were investigated by means of simultaneous distillation-extraction, GC, and GC-MS. Three hundred and seventy-two compounds were identified, of which 180 were found for the first time in mango fruit. The total concentration of volatiles was approximately 18-123 mg/kg of fresh fruit. Terpene hydrocarbons were the major volatiles of all cultivars, the dominant terpenes being delta-3-carene (cvs. Haden, Manga amarilla, Macho, Manga blanca, San Diego, Manzano, Smith, Florida, Keitt, and Kent), limonene (cvs. Delicioso, Super Haden, Ordonez, Filipino, and La Paz), both terpenes (cv. Delicia), terpinolene (cvs. Obispo, Corazon, and Huevo de toro), and alpha-phellandrene (cv. Minin). Other qualitative and quantitative differences among the cultivars could be demonstrated.

The chemical composition of cold-pressed mandarin peel oil from Cuba was studied by GC and GC/MS. Eigthy-five compounds of the oil were identified of which limonene (78.3 %) and γ-terpinene (7.2 %) were the major constituents. The composition of the peel oil is characterized by higher percentages of monoterpene and sesquiterpene hydrocarbons and the presence of many aliphatic saturated and unsaturated aldehydes at lower concentrations.
