Carotenoids, Polyphenols, and Ascorbic Acid in Organic Rosehips (Rosa spp.) Cultivated in Lithuania

Abstract

Carotenoids, polyphenols, and ascorbic acid are valuable and important biologically active compounds that contribute to the health benefits of different foods, and rosehips are known for their high biologically active substance contents. The aim of this research is to identify and compare the contents of carotenoids, polyphenols, and ascorbic acid in the flesh and seeds of different rosehip species grown organically. A field experiment was conducted during the period 2017–2018 on an organic farm in Lithuania. Rose fruits were collected at full ripening in September. The quantitative and qualitative determinations of polyphenols and carotenoids in rosehips flesh and seeds were conducted by HPLC methods. The following polyphenolic compounds were identified: five different flavonoids (rutin, kaempferol-3-O-glucoside, luteolin, quercetin, and quercetin-3-O-glucoside) and five phenolic acids (gallic, chlorogenic, caffeic, p-coumaric, and ferulic) from different rose fruit fleshes and seeds species. In addition, six carotenoids (β-carotene, α-carotene, lutein, zeaxanthin, cis-lycopene, and trans-lycopene) in rosehip flesh and five different carotenoids in rosehip seeds (α-carotene, lutein, zeaxanthin, cis-lycopene, and trans-lycopene) were identified. Overall, the results of this study demonstrate that the highest content of total phenolic acid is in rosehip seeds, while higher concentrations of carotenoids, flavonoids, and ascorbic acid are present in rosehip flesh.

Rosehip Extract-Functionalized Magnesium Hydroxide Nanoparticles and Its Effect on Osteoblastic and Osteoclastic Cells

“…Additionally, the presence of phytochemicals in the particles, as confirmed on the ATR–FTIR spectrum ( Figure 1 ), is also expected to play a role. Rosehip bears high levels of bioactive molecules such as flavonoids, carotenoids, and ascorbic acid [ 32 , 54 , 55 , 56 ]. These compounds have been reported to preserve bone health and prevent metabolic-related bone loss conditions [ 32 , 57 , 58 , 59 , 60 ], improving osteoblastogenesis by reducing the effects of oxidative stress or chronic low-grade inflammation [ 57 , 59 ].…”

Morphological and Biochemical Diversity in Fruits of Unsprayed Rosa canina and Rosa dumalis Ecotypes Found in Different Agroecological Conditions

“…Flavonoids impact the aroma and color of fruits and against biotic and abiotic stressors [45]. Medveckiene et al [46] reported that total flavonoid content is species dependent in Rosa, and the highest total flavonoid content found as 41.59 mg/100 g DW. Rosehips accumulated a higher amount of total flavonoids ranged from 52 mg/100 g to 56 mg/100 g [20,47].…”

“…Koczka et al [52] reported 150-299 mg/100 g DW total polyphenols in fruit flesh of rosehips. Medveckiene et al [46] used several species of Rosa and reported that total polyphenol content in flesh varied from 150 to 299 mg/100 g DW. Fascella et al [53] showed between 4057 and 6784 mg GAE/100 g DW total phenolic content among Rosa species.…”

Rose Hips, a Valuable Source of Antioxidants to Improve Gingerbread Characteristics

“…The all-trans-lycopene level was rather high [29]. Medveckiene et al (2020) researched the chemical structure of carotenoids in the pulp of five varieties of rose hip fruits and found that lutein and zeaxanthin range between 12.89 and 20.53%, β-carotene between 45.56 and 70.34%, α-carotene between 6.97 and 13.51%, and lycopene between 9.29 and 24.68% of the total amount of carotenoids [30]. Al-Yafeai et al (2018) studied the profile of carotenoid compounds in saponified extracts of rose hip fruits at different stages of maturation, and identified the following xanthophylls: violaxanthin, lutein, zeaxanthin and rubixanthin, as well as β-carotene and lycopene [31].…”
