Assessment of Chemical and Antioxidant Properties of Fresh and Dried Rosehip (Rosa canina L.)

Abstract

This work aimed to evaluate the nutritional and functional properties of rosehip from Serbia. In respect to that, the content of twenty-three elements in the rosehip along with the soil were determined by inductively coupled plasma-optical emission spectroscopy and the bioaccumulation factor (BAF) was calculated. The total dry matter, water activity, and the contents of vitamin C, total phenolics and flavonoids were determined. The antioxidant ability of fresh and dried samples was evaluated using 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging assay. The obtained extracts were analyzed by gas chromatography with flame ionization detection and gas chromatography – mass spectrometry techniques. In addition, assessment of the impact of thermal treatment on the chemical composition of rosehip was observed. The study revealed that the most abundant elements in rosehip were K, Ca, Mg, P and S with 2963.0, 1820.0, 709.0, 495.0 and 289.8 mg/kg, respectively. The highest BAF values in the system rosehip/soil were for S, K and P. Contents of ascorbic acid, total phenolics, total flavonoids and the antioxidant activity were reduced after the drying process by 56.3%, 20.4%, 31.3%, 21.9%, respectively. Nevertheless, dried rosehip was still a rich source of bioactive compounds with significant antioxidant activity. The presented results support traditional use of rosehip as food with health and nutritional benefits.

Phytochemical Screening and Antioxidant Analysis of the Ethanolic Extract of Rosehip Seed Press Cake

“…The TPC recorded in this study for the pressed rosehip seeds was much higher than that of the rosehip fruits in Paunovic et al (2019). The rosehip seeds constitute a larger portion of the rosehip fruits, hence the TPC of the pressed seeds in our study is greater.…”

“…The TFC of the ethanolic extract of the pressed rosehip seeds in this study was found to be higher than that of all the extracts from rosehips reported by [24]. Similarly, Paunovic et al (2019) also reported the TFC of the ethanolic extracts of fresh and dried rosehips [25]. The TFC of the fresh and dried fruits was found to be 38.52±0.82 and 26.47±1.03 mg QE/g DW, respectively [25].…”

“…This suggested that, the nature of plant materials and the solvents used are the major contributing factors in the measurement of TPC. Paunovic et al (2019) also reported the TPC of the ethanolic extracts of fresh and dried rose hips in which 70% ethanol was used to effect extraction [25]. The TPC of the fresh and dried fruits was found to be 90.51±0.53 and 72.09±1.08 mg GAE/g DW, respectively [25].…”

Fruit phytochemical composition and color parameters of 21 accessions of five Rosa species grown in North West Iran

“…6,7,[14][15][16][17][18] Recently, breeding programs of different Rosa species have been focused on the quality and quantity of phytochemical compounds such as vitamin C and the phenolic composition in rosehips. [19][20][21][22] In recent years, global trends show that the use of rosehips and their products is increasing. 23 The inclusion of wild species that have valuable compounds is important and necessary in breeding programs.…”

“…Several studies have shown the genetic diversity of different Rosa species based on phytochemical diversity . Recently, breeding programs of different Rosa species have been focused on the quality and quantity of phytochemical compounds such as vitamin C and the phenolic composition in rosehips . In recent years, global trends show that the use of rosehips and their products is increasing .…”
