“…The impact of Japanese quince genotype on the seed oil yield was not studied previously, nevertheless, a similar oil extractability from Japanese quince seeds, as obtained in the present study, by the ultrasound‐assisted and cold‐press extraction methods were reported previously . The importance of the genotype of plants belonging to the Rosaceae family for potential oil extraction from seeds and kernels has been underlined as an important economic factor …”

The impact of the extraction technique and genotype on the oil yield and profile/concentration of fatty acids, tocopherols, sterols, and squalene in oil obtained from the seeds of three Japanese quince (Chaenomeles japonica) cultivars (“Rondo,” “Darius,” and “Rasa”) are studied. The oil recovery from Japanese quince seeds is affected by two factors; extraction technique, and genotype. The lowest oil recovery is recorded for the cold‐press method and cv. “Rondo,” and the highest for ultrasonic extractions and cv. “Rasa.” The profile of fatty acids in Japanese quince seed oil is dominated by three fatty acids C18:2, C18:1, and C16:0. The extraction method does not impact fatty acid and tocopherol composition as well as squalene content, as opposed to genotype, which has a statistically significant impact. The composition of tocopherols in the Japanese quince seed oil is dominated by the α‐T (97%), while the β‐T and γ‐T constituted only minor level (below 2% of each). The extraction type and genotype have a significant impact on the composition of the most of sterols. Regardless of the type of extraction and genotype, the β‐sitosterol consists of over 80% of total sterols in Japanese quince seed oil. The plant genotype is the key factor, which determines the profile of the fatty acids and the concentration of bioactive compounds in the extracted oil from Japanese quince seed, while the extraction technique plays a secondary role. Practical Applications: The agro‐industrial by‐products generated by the fruit industry, for example, seeds, continue to rise year to year. One of the more popular processed fruit crop is Japanese quince (Chaenomeles japonica). This study demonstrates the impact of the extraction technique (four methods of extractions: cold‐pressing, supercritical CO2 fluid, ultrasound‐assisted, and Soxhlet) and genotype (three cultivars “Rondo,” “Darius,” and “Rasa”) on oil yield, fatty acid profile, and concentration of tocopherols, sterols, and squalene. Provided information can help with more efficient utilization of the tonnes of seeds generated by the fruit industry and consequently contributing to the more effective use of harvested plant material as well as health, economic, and environmental benefits.

“…There is no significant influence of the debitterizing treatment on the contents of oils in the apricot kernels (data not shown), so only the composition of the fatty acids was investigated in this research. Although some other bioactive compounds such as tocopherols, sterols, squalene, and carotenoids are also included in the oils of apricot kernels, yet the contents are significantly lower than those of sugars, proteins, and phenols (Górnaś et al, ; Rudzińska, Górnaś, Raczyk, & Soliven, ); therefore, these lipophilic compounds will be investigated in future. The profiles of fatty acids in the apricot kernels were conducted by the GC–MS; one of the typical total ion chromatograms is presented in Figure , and the main fatty acids compositions and their relative contents are listed in Table .…”

In this article, the conventional debitterizing treatment of apricot kernels in industrial processing was investigated to study its effect on the quality of the kernels including the amygdalin, protein, sugars, and phenols dissolved in the debitterized water, as well as fatty acids, peroxide value (PV), and acid value (AV) in the kernels. The results indicate that the debitterizing temperature and time positively correlated with the contents of those detected components in debitterized water.Furthermore, the most changes of PV, AV, and fatty acids' composition are significant, which suggest that the debitterizing caused the oxidation and rancidity in the apricot kernels oil. Overall, the debitterizing not only decreased the toxicity of the apricot kernels to make it suitable for consumption but also caused a great loss of quality of apricot kernels, as well the problem of environment pollution, which has been a serious issue to be urgently solved for the apricot kernels processing industry. Practical applicationsThis report mainly focused on the debitterizing treatment on the quality of apricot kernels, in addition, some suggestions were made to improve the debitterizing efficiency and lower the discharge of wastewater. These results and suggestions are very useful to control and produce the high quality apricot kernels with minimal waste, especially under the new situations of requiring lower carbon emission, lower pollution, and full utilization of resources.

“…α‐T, δ‐T, γ‐T3, α‐T3, and β‐T constituted small percentages: 4.2, 2.0, 1.1, 0.4, and 0.1%, respectively. A predominance of γ‐T (on the levels 90% of total tocopherols) was reported also in the seed oils recovered from plants such as watermelon ( C. lanatus ), pomegranate ( Punica granatum ), gooseberry (Górnaś et al, ), pear ( Pyrus communis ) (Górnaś et al, ), and apricot ( Prunus armeniaca ) (Górnaś et al, ).…”

The beneficial and potentially harmful bioactive components in the seeds and seed oil of Trichodesma indicum L. (Boraginaceae) were investigated in the present study. The T. indicum seeds were rich in oil (29.0%), phenolic compounds (PC, 1881.2 mg per 100 g), and pyrrolizidine alkaloids (PA, 2,702,338 ng g −1 ). Seven PC were identified in T. indicum seeds by liquid chromatographyquadrupole-time-of-flight mass spectrometry system (LC-Q-TOF-MS). Rosmarinic acid (67%) and isomers of salvianolic acid B/E/L (26%) were the main phenolics, while melitric acid A and sebestenoid C/D constituted 6% and 1%, respectively. Only a minor part of the total PC and PA was transferred from the seeds into the oil fraction during the extraction procedure (<0.03%). The T. indicum seed oil was predominated by the following polyunsaturated fatty acids (PUFA):linoleic (23.2%), γ-linolenic (6.0%), α-linolenic (26.8%), and stearidonic (5.9%). High levels were also observed for oleic (26.7%) and palmitic (7.4%) acids. Additionally, notable amounts of γ-tocopherol (92% of total tocochromanols) and β-sitosterol (53% of total sterols) were found in T. indicum seed oil. The total content of tocochromanols, sterols, and carotenoids in T. indicum seed oil was 102.7, 236.0, and 0.6 mg per 100 g oil, respectively. Among 10 detected hepatotoxic PA in T. indicum seeds, intermedine/lycopsamine/indicine (90.9%), intermedine N-oxide (4.9%), and lycopsamine N-oxide (4.1%) consisted 99.9% of the total PA concentration. The T. indicum seeds should be used carefully due to the presence of PA.
