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 (86.7–90.3%). 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 diferente 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.
