Fatty acid, vitamina E and sterols composition of seed oils from nine different pomegranate (Punica granatum L) cultivars grown in Spain
[EN] The present study was conducted to determine the major bioactive lipid components of the seed oils of
nine pomegranate (Punica granatum L.) cultivars grown in Spain, namely fatty acids, vitamin E and sterol
compositions. The seeds yielded oil contents ranging from 4.44% to 13.70% of dry matter and showed
high contents of polyunsaturated fatty acids (86.7.2–90.3%). The predominant fatty acid was 9,11,
13-octadeca-trienoic acid (punicic acid), a conjugated linolenic acid characteristic from pomegranate
seeds, with contents between 3523 and 10,586 mg/100 g of seeds. Total tocopherol contents ranged
from 135 to 525 mg/100 g of oil, with g-tocopherol as the main component, and with different
compositional ratios between varieties. Concerning sterols in the oil, total amounts ranged from 364 to
553 mg/100 g, with a predominance of b-sitosterol. After performing principal component analysis,
intercultivar differences were found, a potential tool for cultivar authenticity purposes. Moreover, the
ingestion of pomegranate arils, with their seeds, increases their beneficial health properties.Authors are grateful to POCTEP - Programa de Cooperacao Transfronteiriga Espanha - Portugal for financial support (Project "RED/AGROTEC-Experimentation network and transfer for development of agricultural and agro industrial sectors between Spain and Portugal) as well as to the European Union (FEDER funds through COMPETE) and National Funds (FCT, Fundacao para a Ciencia e Tecnologia) through project Pest-C/EQB/LA0006/2013.Fernandes, L.; Pereira, JA.; López Cortés, I.; Salazar Hernández, DM.; Ramalhosa, E.; Casal, S.

Determination of geographical origin Turkish hazelnuts according to fatty acid composition
This study focuses on detecting geographical origin of round type hazelnut (Corylus avellena L.) in Turkey using fatty acid (FA) composition. The samples were collected from Western, Central, and Eastern Black Sea regions between 2015 and 2016. FA profiles were determined by gas chromatography (GC), and most abundant fatty acid was oleic acid (C18:1) followed by linoleic acid (C18:2), palmitic acid (C16:0), and stearic acid (C18:1). The effect of geographical origin on the fatty acid profile of hazelnut oils was statistically analyzed by one‐way ANOVA and linear discriminant analysis (LDA). The results showed that the Central Black Sea region had high content of total saturated fatty acids (%8.45), total monounsaturated fatty acids (%83.54), low content of total polyunsaturated fatty acids (%7.85), and Eastern Black Sea region had high content of linoleic (%9.10) and linolenic acid (%0.096). Six fatty acids (C16:1, C18:1, C18:2, C18:3, C20:0, and C20:1) identified by LDA provide 86.2% of correct predictions
