Bioactive compounds and antioxidant activity of Rosa canina L.biotypes from spontaneous flora of Transylvania

Abstract

BackgroundThe theoretical, but especially the practical values of identifying the biochemical compounds from the Rosa canina L. fruits are of present interest, this aspect being illustrated by the numerous researches. It was reported that the Rosa canina L. fruit, with its high ascorbic acid, phenolics and flavonoids contents, have antioxidant, antimutagenic and anticarcinogenic effects.This study was performed on order to evaluate the amount of the main phytochemicals (vitamin C, total polyphenols, and total flavonoids) content and their antioxidant activity.ResultsThe results obtained revealed that the average amounts of vitamin C within the studied genotypes were: 360.22 mg/100 g frozen pulp (var. transitoria f. ramosissima, altitude 1250 m) and 112.20 mg/100 g frozen pulp (var. assiensis, altitude 440 m), giving a good correlation between the vitamin C content of the rosehip and the altitude. The total polyphenols content varied from 575 mg/100 g frozen pulp (var. transitoria f. ramosissima) to 326 mg/100 g frozen pulp (var. lutetiana f. fallens). The total flavonoids content showed the highest value for var. assiensis variant 163.3 mg/100 g frozen pulp and the lowest value attributed to var. transitoria f. montivaga 101.3 mg/100 g frozen pulp. The antioxidant activity of eight rose hip extracts from wild Transylvania populations was investigated through DPPH method. The antioxidant activity revealed a good correlation only with vitamin C content and total polyphenols.ConclusionEight Rose hip fruit species were compared taking into consideration the ascorbic acid, total polyphenols, total flavonoids contents and their antioxidant activity. Based on these results, two of the rosehip genotypes that were analysed could be of perspective for these species’ amelioration, due to their content of phytochemicals mentioned above. These varieties are var. transitoria f. ramosissima (Bistrita-Nasaud, Agiesel) and var. transitoria f. montivaga (Bistrita-Nasaud, Salva) which can be used as a potential source of natural antioxidants.

Biochemical and Technological Properties of Rosa Canina L. Fruits from Spontaneous Flora of Oltenia, Romania

“…Some authors said that Rosa canina fruits are rich in vitamin C and presents benefic effect on human health (Haas, 1995;Demir and Özcan, 2001;Mabellini et al, 2011;Roman et al, 2013).…”

“…Mn, Zn, Na, B, flavonoids and carotenoids such as lycopene, the pigment that gives the redorange (Demir and Özcan, 2001; Kazaz et al, 2009), polyphenols (Roman et al, 2013). The oil of dog rose seed contains fatty acids like oleic, linoleic, palmitic, stearic, and arachidonic (Özcan, 2002;Kazaz et al, 2009).…”

Thermal degradation kinetics of ascorbic acid, thiamine and riboflavin in rosehip (Rosa canina L) nectar

“…The main importance of rosehip is its high composition of vitamin C and rutin (vitamin P) and high content of pectins, fatty acids, sugars, organic acids, phenolic components, lycopene, carotene with activity of vitamin A and group B vitamins, tannins, carotenoids, minerals (particularly K and P) macro-and microelements (Tuer & Russel, 1989;Demir & Özcan, 2001;Kadakal et al, 2002;Roman et al, 2013;Abacı et al, 2016). In addition to vitamin C, rosehip contains thiamine, riboflavin, E and K vitamins (Stundzhya & Shnaidman, 1972;Yamankaradeniz, 1983;Tuer & Russel, 1989).…”

Farklı Test Sistemleri ile Somatik Hücrelerde Profenofos Genotoksisitesine Karşı Kuşburnu (Rosa canina L.) Ekstrelerinin Doğal Bir Antigenotoksik Ajan Olarak Kullanılması

“…Araştırıcılar elde ettikleri verilerin sonucunda kuşburnunun sadece besin olarak düşünülemeyeceğini, tedavi edici potansiyelinden dolayı biyoaktif moleküllerin de önemli bir kaynağı olduğunu dile getirmişlerdir. Roman et al [42], çalıştığı diğer kuşburnu türlerine göre R.canina'nın biyoaktif bileşikler yönü ile daha zengin olduğunu belirlemiştir. Kuşburnu tohumu ile beslenen farelerde plazma kolesterol ve trigliserit oranının önemli derecede azaldığı dolayısı ile kuşburnunun diyet gıdalarda kullanılabileceği ifade edilmiştir [43].…”
