Ouricuri (<i>Syagrus coronata</i>) triacylglycerol analysis using HPLC and positive ion electrospray tandem MS

Abstract

Abstract Among tropical oil sources in Brazil, the ouricuri ( Syagrus coronata ) tree is nearly ubiquitous. The exact TAG composition of oil from ouricuri fruits was elucidated with electrospray ionization/tandem MS. The oil contains the following FA: caprylic (Cy), capric (Ca), lauric (La), myristic (M), palmitic, stearic, oleic, and linoleic. An estimate of the relative TAG composition based on the neak areas using an ELSD indicated that the four primary TAG—CyLaLa, CaLaLa, CaLaM, and LaLaM—corresponded to 24.3, 19.8, 13.6, and 10.9%, respectively, of the total TAG content.
