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 C13 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 C13 norisoprenoids as the main glycosidically linked volatile compounds.
