AuNPs have been in the focal point of researchers’ attention for years because of high biocompatibility and adjustable surface plasmon resonance (SPR) [1]. In the recent years, many studies have been performed in producing AuNPs via green synthesis techniques, i.e. use of plants for producing AuNPs [2]. Green synthesis methods are eco-friendly and increase the biocompatibility of AuNPs [3]. A f...

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...
