“…This lack of a relationship is in agreement with other reports [48] that also obtained negative correlation. In other studies, a low correlation was obtained [45,51,52], pointing out that flavonoids did not contribute to the antioxidant activity of some fruits.…”

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.

“…In previous studies dealing with correlations of the phenolics compounds to DPPH, the scavenging activity showed that the polyphenols were involved with a very different coefficient of determination R 2 = 0.723 [41]; R 2 = 0.411 [48]; R 2 = 0.086 [36]. …”

“…Findings obtained from 80% ethanol extract demonstrated the cytoprotective effects against human lung carcinoma and rat adrenal medulla cancer cells [ 13 ]. Such activities were essentially related to free radical scavenging capacities, as that has been demonstrated in many works [ 13 , 14 ]. In addition, fruit extracts from L. europaeum are characterized by high content of flavonoids, anthocyanins, carotenoids, lycopene, and tannin [ 13 ]; these constituents have indicated potential biological activities.…”

This study was designed to assess the protective effects of Lycium europaeum methanol extract (LEM) on liver and kidney injuries induced by cisplatin. The phytochemical composition, the antioxidant activity, and hepatorenal injury biomarkers were investigated. Results revealed that LEM exhibited a significant antioxidant activity in vitro on DPPH radical and H2O2 scavenging assays. In the animal studies, treatment with LEM significantly reduced the effects of cisplatin intoxication on serum liver biomarkers and serum renal biomarkers. Meanwhile, LEM diminishes significantly the effect of cisplatin on the level of lipid peroxidation in liver and kidney tissues. The activities of the antioxidant enzymes (reduced glutathione, glutathione peroxidase, superoxide dismutase, and catalase) were increased in groups pretreated with LEM and quercetin. Additionally, the normal histological structures of the liver and kidney were restored after treatment with LEM. This work clearly demonstrated that L. europaeum may be useful as a drug with hepato-nephroprotective potentials.

“…Our finding partially agrees with the CTCs of Algerian (74.22-394.27 mg CE/100g), Tunisian (41.85-102.37 mg CE/100g), and Moroccan (57.56-92.14 mg CE/100g (dw)) date fruits at Tamr stage (Arem et al, 2013;Benmeddour et al, 2013;Bouhlali et al, 2016;Souli et al, 2018). Total amount of condensed tannins in date palm fruit is lower than hawthorn (920-4110 mg CE/100g) and higher than strawberry (2.93-31.55 mg CE/100g), rosehip (2.02-2.34 mg CE/100g), blackberry (14.28-16.59 mg CE/100g), and blackthorn (9.53-10.50 mg CE/100g) (Dou, Leng, Li, Zeng and Sun, 2015;Turker, Kizilkaya, Cevik and Gonuz, 2012).…”

In the present study, it was aimed to produce free-flowing date powders using various levels of inulin as dryingaid agent (10, 20, 30, 40, and 50%) through hot-air drying at 60°C for 24 h. Effects of different inulin ratios on physicochemical properties of date powders were investigated. This is the first report which evaluated the suitability of this prebiotic carbohydrate as drying-aid agent to fabricate date powders. Inulin addition yielded date powders with high flowability. On the other hand, contents of bioactive compounds including total phenolics, flavonoids, and condensed tannins of date powders decreased significantly (P<0.05) as the inulin concentration increased from 10% to 50% Accordingly, DPPH-radical inhibition capacities reduced in date powders containing higher levels of inulin. Furthermore, significant correlations were detected between bioactives contents and antioxidant activity of date samples. The results showed that free-flowing date powders with improved prebiotic content may be produced by incorporating inulin up to ratio of 50% and used as sugar substitute in different food products.
