Relatıonshıp Between Vıtamın and Antıoxıdant Actıvıtıes of Rosehıp Specıes Grown in the same Ecologıcal Condıtıons

Abstract

The realisation of the high chemical potential of the fruits of Rosa species, which were initially used for seasonal consumption and in the treatment of a wide range of ailments, led to an increase in consumption and research into the possibilities for use. In order to determine the usage possibilities of these fruits and their various chemical properties, it is necessary to know about the antioxidant activity, the amount of vitamins, phenolic and flavonoid substances within rose species. In this study, naturally growing ecological friendly fruits of Rosa villosa L. subsp. mollis (R1), Rosa villosa L. subp. villosa L. (R2), Rosa pimpinellifolia (R3), Rosa iberica (R4), Rosa pisiformis (R5) and Rosa canina (R6) were investigated with respect to their vitamin values (A, E and C vitamins), total phenolic (TPC), flavonoid (TFC) content, and antioxidant potentials. The correlation ratios of these properties were also checked during this study. The recent study showed that the highest amount of TPC and TFC were 142.08±2.16 mg GAE/g, 8.04±0.47 mg QE/g, respectively in R1, and the highest vitamin values were determined which were vitamin A at 397.17±13.58 µg/mL in R5, Vitamin E at 19.52±0.82 µg/mL in R4 and vitamin C at 606.53±0.38 µg/mL in R1. DPPH, FRAP and CUPRAC methods, which are reliable methods, were used to determine the antioxidant potential. The highest antioxidant potential was measured in R1 by DPPH and FRAP methods. In R3, it was found that the Cu2+ reduction antioxidant activity was the highest with the CUPRAC method. In addition, it was understood that the correlation analysis among the determined characteristics of the species was statistically significant. There was a high positive correlation between TFC and vitamin E value in R1 while this postive relationship was also found between TPC and E in R2. As a result, although significant quantitative differences were detected between Roseship species in this study, it was determined that the antioxidant potentials and vitamin values of all species were high. The results showed that the important the fruits of these species would be used for human nutrition and health. In addition, the antioxidant potential and vitamin C value of Rosa villosa L. subsp. mollis (R1) were found to be very high and it was concluded that the fruits of this species would be more suitable for use in the pharmaceutical, functional food and cosmetic industries. It can be suggested that the further studies should be conducted in order to spread the consumption of fruits belonging to these species. © 2024, Pakistan Agricultural Scientists Forum.
