Chemical Composition and Antioxidant Capacity of Brazilian Passiflora Seed Oils

Abstract

The seed oils of different varieties of 4 Passiflora species cultivated in Brazil were analyzed and compared regarding their physicochemical parameters, fatty acid composition and the presence of minor components, such as phytosterols, tocopherols, total carotenoids, and phenolic compounds. The antioxidant capacities of the oil extracts were determined using the 2,2'azinobis [3-ethylbenzothiazoline-6-sulfonic acid] and oxygen radical absorbance capacity methods. The results revealed that all studied Passiflora seed oils possessed similar physicochemical characteristics, except for color, and predominantly contained polyunsaturated fatty acids with a high percentage of linolenic acid (68.75% to 71.54%). Other than the total phytosterol content, the extracted oil from Passiflora setacea BRS Pérola do Cerrado seeds had higher quantities (% times higher than the average of all samples), of carotenoids (44%), phenolic compounds (282%) and vitamin E (215%, 56%, 398%, and 100% for the α-tocopherol, β-tocopherol, γ-tocopherol, and δ-tocopherol isomers, respectively). The methanolic extracts from Passiflora setacea BRS Pérola do Cerrado seed oil also showed higher antioxidant activity, which was positively correlated with the total phenolic, δ-tocopherol, and vitamin E contents. For the first time, these results indicate that Passiflora species have strong potential regarding the use of their seeds for oil extraction. Due to their interesting composition, the seed oils may be used as a raw material in manufacturing industries in addition to other widely used vegetable oils.

Assessment of chemical, nutritional and bioactive properties of Annona crassiflora and Annona muricata wastes

“…Dther fruits and seeds from Cerrado exhibited higher carotenoid concentration than soursop and marolo seeds. According to Silva et al (2014a), jatobá-do-cerrado flour contains 17000 µg β-carotene kg -1 ; Santana et al (2015) analyzed the seeds of sweet passionfruit (Passiflora alata) and found 129260 µg β-carotene kg -1 (d.b. ); Dliveira et al (2017) reported 6921 µg β-carotene kg -1 of oil for pequi (Caryocar brasiliense) almond.…”

Contractile function recovery in severely injured gastrocnemius muscle of rats treated with either oleic or linoleic acid

“…The composition of fatty acids in gastrocnemius muscle (100 mg) was determined by gas chromatography, according methods previously described (Feldsine et al 2002;Ratnayake et al 2002). A similar procedure has been used in our studies (Afonso et al 2013;Hirabara et al 2013;Fariña et al 2014;de Santana et al 2015). The results are presented as the mean ± SD of four animals per group.…”

Acute Effects of the Consumption of Passiflora setacea Juice on Metabolic Risk Factors and Gene Expression Profile in Humans

“…PS pulp and seeds have recently been identified as rich in BC, particularly in C-glycosides of flavonoids [18], and also homoorientin, vitexin, isovitexin, and orientin at higher contents than those found in Passiflora edulis, açaí (Eurydema oleracea), and orange juice [19]. They have also revealed antioxidant and antimicrobial properties in vitro [20,21]. These effects are potentially due to the presence of vitamin E and BC such as terpenoids, polyamines, and polyphenols, especially orientin, isoorientin, vitexin, and isovitexin [17][18][19]21].…”
