“…Trace amount of the fatty acids were also identified and these data are similar to those reported by Kostadinovic Velickovska et al, 2015. On the other hand, there are insignificant differences in fatty acid profiles between these results and those reported by Nederal et al, (2014). The differences in profile and amount of certain fatty acids depended on the origin of specific pumpkin (Cucurbita pepo L.) seed oil cultivars, climatic conditions, and post-harvest management (Rabrenovic et al, 2014).…”

“…Based on the position of the double bond in the ring, phytosterols could be classified as ∆5-and ∆7-sterols. Most species contain dominant ∆5-sterols, while ∆7-sterols are characteristic of only a few plant species and are specific bioactive compounds to pumpkin seed (Cucurbitaceae) oil (Rabrenovic et al, 2014). The phytosterol profile of the PSOs is given in Table 2 and regression analyses were also performed.…”

SUMMARY:There is a growing interest in cold-pressed oils because they present high contents of bioactive compounds. These oils have the characteristic properties of seeds and are specific products of their regions. The aim of this study was to determine the compositions and contents of fatty acids, phytosterols, squalene, tocols, phenolic acids, carotenoids and phenolic bioactives, and the free radical scavenging as well as antioxidant activities of coldpressed pumpkin (Cucurbita pepo L.) seed oils. Oil samples from raw pumpkin seeds cultivated in four different central Anatolia regions of Turkey were prepared using a laboratory screw-pressing machine. The results indicate that coldpressed pumpkin seed oils (PSO) have excellent quality with high contents of polyunsaturated fatty acids (%∑PUFAs) (53.60 ±0.06−53.73 ±0.05), total phytosterols (782.1±9.7-805.2 ±11.3 mg/100 g oil), squalene (591.3±10.6-632.5±11.4 mg/100 g oil), tocols (97.79 ±0.76−94.29 ±0.34 mg/100 g oil), phenolic acids (22.73 ±0.41-23.98 ±0.46 mg/100 g oil), carotenoids (6.95 ±0.03-7.60 ±0.03 mg/100 g oil), total phenolics (3.96 ±0.13 -5.82±0.15 mg GAE/100 g), free radicalscavenging activity (5.70 ±0.13−7.35 ±0.15 mg GAE/100 g) and total antioxidant activity (26.67±0.97−38.89±1.41 mg GAE/100 g) values. Thus, this study demonstrates that the cold-pressed PSOs from the central Anatolia regions of Turkey are an excellent source of natural bioactive compounds, free of chemical contaminants and nutritious.KEYWORDS: Antioxidant activity; Bioactive compound; Cold-pressed oil; Cucurbita pepo L.; Phenolic acid; Tocol profile RESUMEN: Aceites de semillas de calabaza prensados en frío (Cucurbita pepo L.) de la región central de Anatolia en Turquía: Caracterización de fitosteroles, escualeno, tocoles, ácidos fenólicos, carotenoides y compuestos bioactivos de ácidos grasos. Existe un interés creciente en los aceites prensados en frío, ya que presentan altos contenidos de compuestos bioactivos. Estos aceites tienen las propiedades características de las semillas y son productos específicos de las regiones. El objetivo de este estudio fue determinar las composiciones y contenidos de ácidos grasos, fitoesteroles, escualeno, tocoles, ácidos fenólicos, carotenoides y bioactivos fenólicos, la actividad de eliminación de radicales libres, así como las actividades antioxidantes de aceites de semillas de calabaza prensados en frío (Cucurbita pepo L.). Las muestras de aceite de semillas de calabaza cultivadas en cuatro regiones diferentes de Anatolia central de Turquía se prepararon utilizando una máquina de laboratorio de prensado mediante tornillo. Los resultados indican que los aceites de semilla de calabaza prensados en frío (PSO) tienen una excelente calidad, con altos contenidos de ácidos grasos poliinsaturados (%ΣPUFA) (53,60±0,06-53,73±0,05), fitoesteroles totales (782,1±9,7-805,2±11,3 mg/100 g de aceite), escualeno (591,3 ± 10,6-632,5 ± 11,4 mg/100 g de aceite), tocols (97,79±0,76-94,29±0,34 mg/100 g de aceite), ácidos fenólicos (22,73 ± 0,41-23,98 ± 0.46 mg/10...

Pumpkin seed oil (PSO) with carnauba wax and beeswax was used to develop nanostructured lipid carriers (NLC) loaded with a UV filter, Uvinul ® A Plus B. The aims of the study were to optimize the concentration of PSO to develop a stable NLC formulation, determine storage stability of the NLC with and without PSO, and the synergistic effect of PSO-NLC with UV filter for photoprotective properties. The physical properties of NLC were optimized based on the mean particle size, polydispersity index, and storage stability. The optimized NLC consisted 10% lipid phase (3.5% carnauba wax, 3.5% beeswax, and 3.0% PSO) and 90% aqueous phase. After optimization, Uvinul ® A Plus B was added in the optimized PSO-NLC to produce a photoprotective formulation. Uvinul ® A Plus B consisted of both UVA (Diethylamino Hydroxybenzoyl Hexyl Benzoate) and UVB (Ethylhexyl Methoxycinnamate) filters. The NLC produced with PSO and Uvinul ® A Plus B had mean particle size of 135 AE 2 nm and showed good physical stability under storage time. Besides that, the NLC produced also proven to have positive effect in enhancing the entrapment efficiency and drug loading, which were 82.86 AE 0.15% and 55.41 AE 0.04%, respectively, and showed sun protection factor value of 16.61 AE 3.45. The results indicated the presence of synergistic effect among the PSO-NLC with Uvinul ® A Plus B.

The photoprotective skincare products are in high demand to meet the consumer market with concern on skin health. Seed oils are commonly used as ingredients in many cosmetic products due to their natural antioxidants and now being increasingly recognized for their effects on skin health and photoprotection. This article briefly reviews the application of seed oils in sunscreen development focusing on the antioxidants that contribute to photoprotection, thus preventing UV-induced erythema and photoaging. The addition of seed oils that contain specific natural bioactive compounds was discussed in the review. Besides that, seed oils acting in molecular pathways that benefit photoprotection were also summarized. Seed oils (pomegranate seed oil, castor oil, cocoa butter, jojoba oil, rosehip oil, grapeseed oil, kenaf seed oil, and pumpkin seed oil) utilization have high potential to act as natural UV filters and at the same time help in skin repairing. The seed oils contributed beneficial properties to the sunscreen formulation due to their synergistic effect with antioxidants, antiaging properties, anti-inflammatory effect, and potential hormetic effect. The finding of specific bioactive compound from seed oils provides a better understanding of the contribution of seed oils in sunscreen formulation.
