“…The trends were in agreement with those exhibited by the results of DPPH radical scavenging test, confirming that particle size has an important influence on extract antioxidant activity. It can be also noticed that IC50 values obtained with ABTS assay were lower than DPPH assay, this difference between these two tests is consistent with the study of Czyzowska et al (2015).…”

This work evaluated the effect of grinding and sieving process of green tea leaves on particle size distribution and antioxidant activity. Granulometric classes ranging from 20 μm to 500 μm were studied. Hydroalcoholic extracts of green tea powders (GTPs) were analysed for total phenolic, total flavonoid, and catechin contents. The fraction of 100-180 μm ground at 6000 rpm showed the maximum catechin content with 33.5 mg/g dry matter (DM) and, the best antioxidant activity with IC50 values of 0.28 μg/mL and 0.13 μg/mL using DPPH and ABTS radical scavenging assays, respectively. However, antioxidant properties and catechin content decreased for particle of sizes less than 50 μm. Catechin content was higher for those ground at 6000 rpm as compared to at 18,000 rpm. The best grinding conditions and particle size were 6000 rpm and 100-180 μm.

“…The positive effect of this herb on the incidence of UTI can be due to the presence of 880 mg/100 mL of vitamin C (Ercisli, ), or ascorbic acid, that can prevent UTI through its antioxidant properties. The antioxidant effect of this herb was proved in a study by Czyzowska et al () from the Netherlands.…”

“…The antioxidant effect of this herb was proved in a study by Czyzowska et al (2015) from the Netherlands. saprophyticus were assessed in a study conducted in Sweden, and concurrent use of nitrite and vitamin C was found to have a significant effect on inhibiting these UTI-causing bacteria (Carlsson, Wiklund, Engstrand, Weitzberg, & Lundberg, 2001).…”

“…This plant contains about 880 mg/100 mL of vitamin C (Ercisli, 2007) as well as various minerals such as calcium (18 mg/kg), magnesium (1909 mg/kg), iron (267 mg/kg), aluminum (157 mg/kg), manganese (244 mg/kg), zinc (22 mg/kg), and copper (5 mg/kg; Basgel & Erdemoglu, 2006). The antioxidant property of this herb, due to vitamin C (Czyzowska, Klewicka, Pogorzelski, & Nowak, 2015) and antibacterial activity of this herb, due to Flavonoid especially quercetin (Wu et al, 2013), can inhibit the growth of bacteria, particularly Escherichia coli (Kumarasamy, Cox, Jaspars, Nahar, & Sarker, 2002), which causes most of the UTIs (Gary Cunningham et al, 2014).…”

Urinary tract infection (UTI) is an infection that can occur in any area of the urinary tract which is characterized by a positive urine culture (U/C). The risk of UTI following cesarean section (CS) increases due to procedures such as catheterization. In vitro studies have demonstrated the effect of Rosa canina fruit in preventing Escherichia coli growth. This study was conducted to determine the effect of R. canina fruit in preventing the incidence of UTI in women following CS. This triple-blind randomized clinical trial was conducted in 2016 on 400 women following CS with negative U/C in Alzahra and Taleghani educational hospitals in the city of Tabriz-Iran.Participants were assigned into two groups of 200 women using block randomization. Each group received a twice daily dose of 500 mg capsules containing R. canina or placebo from the second day after CS for 20 days. Women were assessed by U/C on the 7th-10th and 20th days following CS. UTI was significantly lower in the intervention group compared with the control in the followups conducted on the 7th-10th days (odds ratio = 0.22; confidence interval 95% [0.07, 0.67]; p = .006) and 20th day (odds ratio = 0.32; confidence interval 95% [0.14, 0.75]; p = .008). But the incidence of cystitis in the two groups was not statistically significant (p > .05). R. canina fruit capsules were able to reduce the incidence of UTI after CS. Thus, it is likely that administration of this medication can promote maternal health following CS.

“…Rosa canina is a widespread wild plant whose rosehips have been used in traditional medicinal remedies in Europe, Asia, and North America [7]. Rosehips have a high content of ascorbic acid, phenolic compounds and other bioactive molecules that are considered responsible for their therapeutic potential.…”

A Combination of Rosa Canina Extracts and Gold Complex Favors Apoptosis of Caco-2 Cells by Increasing Oxidative Stress and Mitochondrial Dysfunction

Given the alarming increase in colorectal cancer (CRC) worldwide, novel therapies are urgently needed. Plant-derived extracts have gained considerable interest in the last years due to their strong anticancer effect mediated by their unique bioactive compounds. Specifically, rosehips from Rosa canina have been successfully tested against several cancer models, including colon cancer. Moreover, gold derivatives are a promising alternative to the current platinum-based drugs commonly used in CRC chemotherapy due to their lack of affinity for DNA. Herein we have investigated the antitumor potential of a drug combination made of acidic polyphenols extracted from R. canina and the gold complex (Au(C≡C-2-NC5H4) (PTA)) in Caco-2 cell line as a model of CRC. The combination triggered strong apoptosis mediated by a blockage of the autophagic flux, which might be a consequence of a reactive oxygen species (ROS) increase and mitochondrial dysfunctionality. Our results suggest that the clinical application of plant polyphenols might enhance the anticancer effect of metallodrugs and reduce drug exposure time and therefore its side effects.
