    In the study, the impact of harvest time on total phenolic content, antioxidant activity, and phenolic compounds of prickly pear (Opuntia ficus-barbarica A. Berger) fruit pulp and the oil content and fatty acids profile of the seed were investigated. The highest total phenolic content was determined as 156.77 mg/100 g in July 1 harvest, while the maximum antioxidant activity and total oil content were found as 9.81% and 6.80% at the last stage of maturation (15 August), respectively. The highest oleic (28.51%), palmitic (22.61%) and stearic acid contents (9.20%) in seed oil were observed in June 15 harvest. The highest value for linoleic acid (57.50%) was detected in August 15 harvest. Prickly pear is a vital source of bioactive constituents such as phenolic and antioxidant substances in terms of being useful for human health and the optimum harvesting time to retain high quantities of most phenolic compounds is 1st July.

    Effect of some plant species on fatty acid composition and mineral contents of Ferulago, Prangos, Ferula, and Marrubium seed and oils
    (WILEY, 2019) Ghafoor, Kashif; Doğu, Süleyman; Ahmed, Isam A. Mohamed; Fadimu, Gbemisola J.; Geçgel, Ümit; Al Juhaimi, Fahad; Babiker, Elfadil E.; Özcan, Mehmet Musa
    The oil contents of seeds were between 4.92% (Ferulago aucheri) and 16.47% (Ferula parva). The highest oleic acid contents were detected in Ferulago syraea (67.15%), Ferulago pauciradiata (67.15%), Ferulago pachyloba (68.82%), Ferulago syriaca (66.16%), Prangos uechtritzii (60.37%), Ferula tingitana (77.26%), and Ferula szowitsiana (58.81%) seed oils. Oleic acid contents of Ferulago spp. (except F. aucheri) oils were found higher than those of other plant seed oils used in experiment (except F. tingitana). The behenic acid content (75.38%) of F. aucheri were significantly higher than other samples. The K contents of plants ranged between 2,888.41mg/kg (F. aucheri Boiss.) and 21,601.26mg/kg (Ferula lycia Boiss.); Ca contents of plants ranged between 5,041.86 (Marrubium catariifolium Desr.) and 39,858.36mg/kg (F. tingitana L.). In addition, the P contents of plants remained between 299.25 (M. catariifolium Desr.) and 4,674.64mg/kg (Marrubium trachyticum Boiss.). The protein contents of plant seeds ranged between 1.75 (F. aucheri Boiss.) and 5.40% (M. trachyticum Boiss.). Practical applicationsPlant seed oils have been used for centuries by rural communities in foods, medicines, cosmetics, and fuel. They have been observed to carry excellent nutritional, nutraceutical, and pharmaceutical values. They are provided with good quantities of different nutrients and important fatty acids. The study will help to understand the differences in fatty acid and mineral composition of different plants from Apiaceae and Lamiaceae families.
