“…The results showed that sunflower exhibited a higher value (11.98 ± 0.36 mg·TE/g) than rapeseed (7.73 ± 0.61 mg·TE/g). The authors in [ 59 ] worked on the antioxidant activity content of seven sunflower seed lines grown in Sudan and reported that the ABTS and FRAP values ranged from 19.46 to 30.70 mg·TE/g and from 29.65 ± 0.87 to 66.06 mg·TE/g, which were consistent with the values found in our study. However, the results of our study did not correlate with [ 60 ], who revealed average values of 15.1 and 26.9 mg·TE/g in ABTS and FRAP, respectively.…”

“…However, the results of our study did not correlate with [60], who revealed average values of 15.1 and 26.9 mg•TE/g in ABTS and FRAP, respectively. According to Abdalla et al (2021) [59], the antioxidant activity of sunflower seed would be assigned to the presence of the enzymatic antioxidants, phenolic compounds, carotenoids, l-ascorbic acid, and peptides, and, according to Mehmood et al [61], the difference between the tested seeds occurred due to variation in the sample, variety, and experimental conditions.…”

We investigate and compare the nutritional and physicochemical properties of rapeseed and sunflower grown in Morocco. In order to examine a complete physicochemical characterization, various parameters such as mineral profile, fatty acid composition, sterols contents, total flavonoids content (TFC), total polyphenols content (TPC), and quality oil parameters were evaluated. The results showed a relatively small difference in the physicochemical composition of the seeds, as sunflower seeds recorded higher amounts of protein and oil content (22.98 ± 0.01 g/100 g and 41.30 ± 0.50 g/100 g) than rapeseed (22.98 ± 0.01 and 38.80 ± 0.50), while mineral elements profile was observed to be statistically different. Nevertheless, both seeds were rich in K, Ca, P, Mg, and Na and they were relatively poor in Na, Fe, Mn, Cu, and Zn. The most represented macroelement was K with the amount of 7936.53 ± 63.87 mg/Kg in rapeseed and 7739.22 ± 59.50 mg/Kg in sunflower. On the other hand, Cu was present in the analyzed samples the least, mostly below 20 mg/kg. For TPC and TFC, the sunflower recorded higher values (49.73 ± 0.50 and 25.37 ± 0.39 mg GAE/g) than rapeseed (38.49 ± 0.24 and 22.55 ± 1.76 mg QE/g). The fatty acid composition showed that both extracted oils have beneficial proprieties, as they are rich in unsaturated fatty acids; namely, rapeseed oil contains a high level of oleic acid (C18 : 1) (62.19%), while sunflower oil was richer in linoleic acid (C18 : 2) (55.7%). As a result, we conclude that the studied varieties have major importance in terms of both nutritional and seed improvement potentials.

“…It's worth to mention that this was the first detailed evaluation of the enzyme inhibitory capacity of the sunflower oil. By comparing these results with previous ones obtained from the seed methanolic extract of the same sunflower lines, it was clear that the oil exerted low enzyme inhibitory potential (Abdalla et al 2021). Moreover, a previous study was performed on the acetone extract of the seed to evaluate its property as α-amylase and α-glucosidase inhibitors (Sonkamble et al, 2018).…”

This study was aimed to evaluate the physicochemical properties and chemical profile of seeds oil obtained from new seven sunflower (Helianthus annuus L.) lines as well as their antioxidant and enzyme inhibition activity. The seeds powder was extracted by maceration in n-hexane. The oil content of the seven lines was ranged from 20.04% to 36.65% and was either yellow or pale yellow in color. No significant variations were observed on the refractive index (1.46 unit) of the oil. Oils of the seven lines were significantly (p ˂ 0.05) different in their saponification values (32.13-282.66 mg KOH/g oil), peroxide values (1.76-13.26 mg KOH/g-oil), acid values (0.016-1.766 mg KOH/g oil) and free fatty acids content (6.26-72.23 mg KOH/g-oil). The chemical profile of the oil revealed that line APO42 contained the highest amount of monounsaturated fatty acids (55.9%). All the seven lines contained a considerable amount of linoleic acid (27.5%-42.5%), and it represented the major compound in lines BOH3 (42.5%) and H1733 (39.8%). The variation was remarkable in their oleic acid content where the highest amount was observed in lines APO42 (55.4%) and APO43 (42.2%), respectively. Lines BOH3, APO43, APO41, and H1733 exerted the best total antioxidant activity in addition to their capacity to reduce Cu 2+ and Fe 3+ , while lines H1733 and APO43 had a metal chelating activity as well. All oils showed weak acetylcholinesterase, butyrylcholinesterase, α-glucosidase and α-amylase inhibitory activities. Only four lines showed considerable enzyme inhibitory activity against tyrosinase enzymes. Multivariance analysis suggested that linoleic acid participated in the observed biological activity of the oils. In conclusion, these new lines might contribute to the nutritional and phytotherapeutic properties of sunflower oil in addition to other industrial applications.

“…Logo, a polaridade do solvente demonstra ser um fator de extrema importância no processo de extração de compostos vegetais, devido à discrepância entre os resultados de rendimento dos solventes mais polares dos mais apolares. Outros estudos também demonstram variação nos rendimentos de extratos brutos, de acordo com o tipo de solvente e parte da planta (VIEIRA et al, 2020;ZHAO et al, 2022), pois cada parte possui maior ou menor concentração de compostos hidrofóbicos ou hidrofílicos, como cascas, que costumam ser ricas em proteínas e carboidratos (GRABEZ et al, 2020;MAYASANKARAVALLI et al, 2020;SHEHATA et al, 2021), e as sementes, que possuem maior conteúdo lipídico (ABDALLA et al, 2021;SONG et al, 2021).…”

Avaliação De Diferentes Extratos Da Casca De Annona Squamosa Para Potencial Analgésico

et al. 2022

Plantas medicinais são cada vez mais investigadas no intuito de encontrar compostos de interesse biotecnológico. Nesse contexto, partes pouco utilizadas de plantas reportadas como medicinais são de alto interesse para bioprospecção e sustentabilidade. Pinha, Annona squamosa, é uma planta frutífera bem utilizada no Brasil e se enquadra nesse perfil. Com isso, o objetivo deste estudo foi comparar a extração de compostos da casca da pinha por diversos solventes e avaliar qual possui melhor atividade analgésica. Pinhas foram coletadas no município de Recife, PE, e o pó da casca foi submetido a extração por água, metanol, acetato de etila, clorofórmio e ciclohexano. Foi realizada triagem para identificação de vários metabólitos primários e secundários e foi realizado teste de analgésico para confirmação do potencial biológico. O rendimento foi de acordo com o grau de polaridade do extrato, extratos com maior polaridade apresentaram maior rendimento. Além disso, os extratos aquoso e metanólico apresentaram maior variedade de constituintes e maior potencial analgésico, pouco mais de 50 %. Água e Metanol se mostraram eficientes na extração de compostos de interesse medicinal da casca da pinha. Destes, a água é tida como o solvente de melhor escolha, tendo em vista o risco de toxicidade causada pelo metanol.
