This work reports the first attempt for detection and identification of chemical compounds in the fruit kernel of the ‘Lodoicea Maldivica’ coco nucifera palm. The analysis was performed by GC-MS technique to determine phytosterol and fatty acid composition profiles in internal and external pulp. Total phytosterol content was almost constant in both kernel coconut (24.6 μg/g for the external, and 22.5 μg/g for the internal portion). The fatty acid pattern has been determined. The composition was characterised by seven saturated acids ranged from C14:0 (myristic) to C20:0 (arachidic) and two monounsaturated acids, the palmitoleic (C16:1, ω7) and the oleic (C18:1, ω9). Palmitic acid (C16:0) was the predominant one with contribution of about 49% followed by pentadecanoic, stearic (C18:0) and myristic acids (C14:0) in all two examined kernel parts.

Abstract
This work reports the first attempt for detection and identification of chemical compounds in the fruit kernel of the ‘Lodoicea Maldivica’ coco nucifera palm. The analysis was performed by GC-MS technique to determine phytosterol and fatty acid composition profiles in internal and external pulp. Total phytosterol content was almost constant in both kernel coconut (24.6 μg/g for the external, and 22.5 μg/g for the internal portion). The fatty acid pattern has been determined. The composition was characterised by seven saturated acids ranged from C14:0 (myristic) to C20:0 (arachidic) and two monounsaturated acids, the palmitoleic (C16:1, ω7) and the oleic (C18:1, ω9). Palmitic acid (C16:0) was the predominant one with contribution of about 49% followed by pentadecanoic, stearic (C18:0) and myristic acids (C14:0) in all two examined kernel parts.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
