Comparison of Free and Glycosidically Linked Volatile Components from Polyembryonic and Monoembryonic Mango (<i>Mangifera </i><i>i</i><i>ndica</i> L.) Cultivars

Abstract

Free and glycosidically linked volatile components of four mango cultivars of polyembryonic (M'Bingué and Tête de Chat) and monoembryonic (Amélie and Palmer) seed origins were examined. Eighty-five free volatile components were identified in the four cultivars, of which 33 are newly described as mango volatile compounds. Terpene hydrocarbons (104, 139, 26, and 35 mg/kg of fresh pulp, respectively) were the major volatiles of all four cultivars (>90% of the total volatiles), the dominant terpenes being ( Z,E )-ocimenes (70%) in Amélie and car-3-ene (80%) in the other cultivars. Free oxygenated volatiles, mainly represented by monoterpenoids, and C 13 norisoprenoids were present in all cultivars, the African Tête de Chat cultivar being by far the richest (12.3 mg/kg). Of the 29 aglycons characterized, 12 were identified for the first time as mango bound volatiles. Again, the Tête de Chat cultivar was the richest (2.1 mg/kg) with monoterpenoids and C 13 norisoprenoids as the main glycosidically linked volatile compounds.
