Values, we detected negative or negligible not considerable values for both ABTS (-0.155) and FRAP (0.098). While pumpkins are viewed as a superb supply of carotenoids, the outcomes obtained within this study apparently look to indicate that carotenoids do not play a significant part within the antioxidant capacity in the accessions chosen. It’s well-known that carotenoids are typically incredibly unstable molecules. As a result, storage, sample preparation, along with other unidentified aspects could account for these not considerable correlation values [23,45]. However, it can be doable that the diverse phytocompounds as discerned by the discriminant terpenoids identified by the VIP strategy reported in Tables 1 and two, on both the origin with the pumpkin accessions and on the two pumpkin species, respectively, could contribute towards the in vitro antioxidant capacity values reported. Notwithstanding the results obtained, carotenoids are regarded as effective Nitrocefin Protocol antioxidants and as such can contribute towards the prevention of aging plus the development of some diseases including atherosclerosis along with other cardiovascular illnesses [42,44,46]. They can also safeguard the eye and macula from degradation, with zeaxanthin getting the predominant carotenoid from the macula pigment and for that reason crucial for eye health [47]. In our study, the outcomes of carotenoid quantification on the pumpkin accessions show that they decreased in the following order of concentration: -carotene -carotene zeaxanthin lutein. These 4 carotenoids were selected considering that they may be probably the most widespread amongst the Cucurbitaceae loved ones [48]. The total carotenoids located in the present study are similar to these reported within the literature for pumpkin merchandise from C. maxima and C. moschata, for example in pumpkin pulp flour [23,49]. Interestingly, on comparing the pumpkin samples based on their origin, we noticed that, normally, these of Serbian origin were characterized by the presence of each -carotene and -carotene, though in those of non-Serbian origin, the presence of -carotene and zeaxanthin was dominant. The results demonstrate that there is certainly high diversity in carotenoid form and concentration within the different Cucurbitaceae species and cultivars, and this can be in accordance with numerous literature reports. For example, Kulczynski and Gramza-Michalowska [27] identified that lutein was the most abundant carotenoid amongst 11 C. maxima cultivars, contrary to our benefits, where it was detected inside the lowest amount, whereas -carotene was by far the most abundant among the C. maxima cultivars in our study. In a earlier study by Kulaitiene et al. [50] on cultivars of the C. maxima species, lutein and zeaxanthin had been essentially the most abundant carotenoids. Azevedo-Meleiro and Rodriguez-Amaya [10] also discovered diverse carotenoids, based on the pumpkin species and cultivar, with C. moschata cultivars possessing greater contents of -carotene too as -carotene and smaller sized amounts of lutein and neoxanthin. On cultivars of C. moschata species, each Norshazila et al. [51] and de Carvalho et al. [52] observed that -carotene was the predominant carotenoid. Nonetheless, a study by Murkovic et al. [28]Antioxidants 2021, 10,13 ofshowed that -carotene was the most dominant carotenoid in most tested pumpkin varieties in both C. maxima and C. moschata fruits from Austria. The above discrepancies may possibly rely on the environmental and developing conditions (Fmoc-Gly-Gly-OH medchemexpress climate, soil, sowing, harvesting, storage). Nevertheless, when such aspects are limited as within the present study, the g.
