“…Similar relations were observed previously in kernels recovered from sixteen different apricot varieties (P. armeniaca) [28]. Much more comparable concentrations of the tocochromanols were reported in kernels of different sweet cherry cultivars [30]. In the plum kernels of the species P. cerasifera and its crossbreeds were noted on average ~20 % lower amount of individual and total tocochromanols, with the exception of δ-T, for which the content was even 50 % lower in comparison with the samples of species P. domestica.…”

“…The same observation was reported in previous studies in kernel oils recovered from plum pits [21][22][23]. In fruit kernels and seeds of plants belonging to the Rosaceae family, the γ-T constitutes in average 87 % in pears (Pyrus communis L.), 88 % in sweet cherry (Prunus avium L.) and up to 93 % in apricots (Prunus armeniaca L.) [28][29][30]. However, the exceptions can be noted, for instance, the apple (Malus domestica Borkh.)…”

“…'Liesma,' respectively. The concentration of α-T and α-T3 found in plum kernels was higher than that reported in pears, sweet cherry and apricots [28][29][30]. Multiple of the lowest in relation to the highest value, of each tocochromanol, was inversely proportional to the concentration and estimated approximately 13-fold for β-T, sixfold for α-T3 and δ-T, threefold for α-T and twofold for γ-T.…”

“…The pear fruits, like many others of Rosaceae family, contain an exceptionally small quantity of seeds (about ten tiny seeds per fruit) which can furnish 15%–31% oleaginous attributes. The profile of bioactive compounds in the oils is affected by species and variety (genotype) of the Rosaceae family (Górnaś, Mišina, Ruisa, et al, ; Górnaś, Rudzińska, et al, ; Rudzińska, Górnaś, Raczyk, & Soliven, ). The most fascinating oleaginous compounds in different species of the pear seed oil include unsaturated fatty acids, tocochromanols, and phytosterols.…”

The high demands for the consumption of edible oils have caused scientists to struggle in assessing wild plants as a new source of seed oils. Therefore, in this study, the oil yield, fatty acid and tocopherol compositions, antioxidant and antibacterial activities of the oils obtained from Iran's two endemic plants (Pyrus glabra and Pyrus syriaca) were investigated. The obtained oil yields from the P. glabra and P. syriaca seeds were 33 ± 0.51 and 26 ± 0.28 w/w%, respectively. Oleic acid (C18:1) with the amount of 49.51 ± 1.05% was the major fatty acid in the P. glabra oil, while the main fatty acids in the P. syriaca seed oil belonged to linoleic acid (C18:2) and oleic acid (C18:1) with the amounts of 46.99 ± 0.37 and 41.43 ± 0.23%, respectively. The analysis of tocopherols was done by HPLC, and the results indicated that the P. glabra and P. syriaca seed oils were rich in α‐tocopherol (69.80 ± 1.91 and 45.50 ± 1.86 mg/100 g oil, respectively), constituting 86.24 and 89.01% of total detected tocopherols, respectively. The study on the reducing capacity of the oils indicated that the P. glabra oil had more reducing capacity than the P. syriaca oil. Moreover, the antioxidant activity of the P. glabra seed oil (43.4 ± 0.7 µg/ml) was higher than the P. syriaca seed oil (46.3 ± 1.2 µg/ml). Also, the investigation of the antibacterial activities indicated that the P. glabra and P. syriaca oils have an inhibitory effect on the studied bacteria. The results indicate that the oils of these plants can be appropriate sources of plant oils which can act as natural antibacterial agents.

A simplified, rapid, and accurate method for sample preparation and determination of tocopherols and tocotrienols (vitamin E) in margarine was developed. For this purpose, 28 margarines with different amounts of fat (20, 39, 60, 70, 75, and 80%) and of two types (spreads and cooking fats) were used. Sample preparation was reduced to a limited number of rapid steps: weighting, melting, diluting, vortexing, and centrifugation, following which the samples were directly injected to the HPLC system. The developed method prevented analyte losses and was characterized by good repeatability and reproducibility (1.4-5.5% and 2.9-9.9%, respectively) and accuracy range (97.9-101.2%) as well as recovery of tocopherols and tocotrienols when compared to the saponification method (89.4-104.4%), without any interference of other compounds from the margarine matrix and thus reduced the risk of potential measurement errors. Fat content in margarine samples did not have any negative impact on precision, accuracy or recovery of tocopherols and tocotrienols. Concentrations of tocopherol (T) and tocotrienol (T3) homologues in margarine samples depended on the fat content and ranged from 2.65-26.27 (a-T), 0.02-0.70 (b-T), 4.23-23.60 (g-T), 0.08-2.34 (d-T), 0.39-15.05 (a-T3), 0.00-1.36 (b-T3), 0.49-20.08 (g-T3), and 0.00-5.28 mg/100 g (d-T3).Practical applications: The necessity to ensure high quality and nutritional value of food products results in the need to develop new high quality analytical methods. This paper describes a simple, rapid and accurate method of sample preparation, preventing analyte losses, and facilitating fast determination of all tocopherol and tocotrienol homologues by RP-HPLC/FLD in margarines containing different amounts of fat (20, 39, 60, 70, 75, and 80%). Margarines are a significant source of vitamin E in our daily diet; therefore, the developed method could be implemented in industry both in routine control and to improve nutrition information about the product provided on the label and also as the first screening test to assess the possible origin of the fat used for margarine production (with tocopherols and tocotrienols as quality markers).
