Fruits along with vegetables are major contributors to our daily vitamin requirements. Both, fruits and vegetables are very important for health because the nutrient contribution is dependent on the amount of vitamins present in these, as well as the amount consumed (1). Vitamin C or ascorbic acid (hereafter AA) is a water-soluble vitamin, which has an important role in all processes of oxidore...

The aim of the present research was to make a comparison between two Bulgarian commercial forms of Rosa canina L. for herbal preparations in terms of the possible benefits by oral intake. The plant samples were investigated for their antioxidant activity and the bioactive substances. The total phenolic content of the extracts was evaluated as well. Four reliable methods (DPPH, ABTS, FRAP and CU...

The new a-pyrone derivative II was isolated in crystalline form from extracts of dormant seeds of Rosa canina. It inhibits germination of seeds of Amaranthus caudatus completely, but reversibly, at conc. > 2.5 x 10~5 m . Its chemical structure was elucidated by mass spectrometry, 'Hand 13CNMR spectroscopy to be 3-methyl-l-oxa-bicyclo (4,1,0) hept-5-en-2-one-4,6-dicarboxylic acid di­ methylester...

in vitro propagation of rose has played a very important role in rapid multiplication of species with desirable traits and production of healthy and disease-free plants. micropropagation using nodal segments of rosa canina under different combinations of bap, ga3 and naa on ms and vs, medium was investigated. the results showed that the highest shoot proliferation was obtained on vs medium cont...

Enzymatic browning, which accompanies food preservation processes based on drying, is a common obstacle to obtaining marketable and consumer-appealing products. In this paper, we investigate the application of one of the methods commonly used in order to counter the browning process, namely dipping. Dipping involves a soaking of the foods in liquids or solutions in order to suppress the activit...

The presented research, comprising characterization of nine species the wild rose (Rosa L.), came from various regions Northern Iraq. study proceeded in 2021–2022 at College Education Pure Science, University Mosul, Employing random amplification polymorphism DNA (RAPD) helped determine genetic variation relationships among using statistical program Numerical Taxonomy and Multivariate Analysis ...

The aim of the present study was to compare carotenoid extracts of Rose hips (Rosa canina L.) with regard to their phytochemical profiles and their in vitro anti-Helicobacter pylori (H. pylori), cytotoxic, multidrug resistance (MDR) reversal and radical scavenging activity. Carotenoid composition was investigated in the different fractionation of rose hips, using extraction methods. Six main ca...

Our research was aimed at assessing the effect of accumulation carotenoids, polyphenols, vitamin C and ripening stage in rosehip fruits two species—Rosa canina, Rosa rugosa cultivar—Rosa ‘Rubra’ ‘Alba’. The amounts polyphenols were determined using high-performance liquid chromatography (HPLC) method. obtained results showed that significantly highest amount (107.15 mg 100 g−1) total carotenoid...
