Abstract

Humans maintain their health by consuming a variety of vegetables and fruits that contain antioxidants, both enzymatic and no enzymatic. Raspberry is one of the most diverse genus of true dicotyledonous plants, which includes 12 subspecies and about 429 species. Raspberry fruit is rich in antioxidant compounds, especially polyphenols. Two species of raspberry were studied to determine the amount of antioxidants and phenolic and flavonoid compounds in their fruits at three different stages of fruit ripening immature, semi-ripe and mature. Natural samples of Rubus idaeus and Rubus strigosus were collected. In this study, the fruit extracts of two species were stored at -23 °C for about six months. Free radical cleansing and Ferric reducing antioxidant power methods were used to determine the antioxidant activities of the extracts. The antioxidant activity of both methods revealed a higher mean value in extracts from fully matured fruits compared with immature and semi-ripe fruits. The results showed that the antioxidant activity of Rubus strigosus is 9%, 10%, and 8% higher than Rubus idaeus in the stages of immature, semi-ripe, and full maturity, respectively.

Highlights

Raspberry is one of the most diverse genus of true dicotyledonous plants, which includes 12 subspecies and about 429 species (Beekwilder et al, 2005; Chen et al, 2020)
Due to the fact that sufficient studies on antioxidant activity have not been performed at present, the aim of this study was to investigate the protective effects of raspberry fruit extract on antioxidant activity and mineral performance
The results related to the Mineral, Antioxidant, And Bioactive contents of Raspberry Varieties are investigated for the determination of the Antioxidant and Mineral contents

Summary

Introduction

Raspberry is one of the most diverse genus of true dicotyledonous plants, which includes 12 subspecies and about 429 species (Beekwilder et al, 2005; Chen et al, 2020). Its four species have the highest economic value as fruit species (Wang & Lin, 2000). This diversity is due to the wide types of fruits and pigments, such as anthocyanins in this genus, which cause red, blue, and purple colors in this genus (Sitpayeva et al, 2021). Raspberry fruit is a complex type and after pollination in the form of a small fruit called a buck to the national existence (Yang et al, 2019). Raspberry species are widely distributed worldwide and have wild, cultivated species and different genotypes that are distributed from the North Pole to Australia (Vukoja et al, 2021)
