Five different rose hip (Rosa L.) species including Rosa canina, Rosa dumalis, Rosa gallica, Rosa dumalis subsp.boissieri and Rosa hirtissima grown in Turkey are studied. Phenolic compounds, organic ...acids, sugar and volatile compounds of five different species of rose hips are studied. Total phenolic contents of the rose hip fruits were significantly influenced by species and the levels of total flavonoid and tartaric esters were almost identical in the samples. Antioxidant activities and antiradical scavenging capacities of the extracts were high levels in all rose hip species. It is noticeable that organic acid and sugar contents of the fruits were highly dependence of species and the high levels of ascorbic acid were characteristic. In total, eighteen different phenolic compounds were identified in rose hip species by RP-HPLC-DAD method and, in particular, R. dumalis subsp. boissiericontained different phenolic compounds. Gallic acid, catechin, procyanidin-B2 and hydroxycinnamic acid derivatives (chlorogenic, t-caffeic, p-coumaric, ferrulic and sinapic acids) were principal for all rose hip species. A total of 52 volatile compounds were identified in rose hip species by SPME/GC-MS and it was characterized by abundance of alcohols and aldehydes with also some monoterpenes and sesquiterpenes.
•Volatiles, phenolics and antioxidant activities of Rosa L. fruits were investigated.•Organic acid and sugar contents of the fruits were highly dependence of species.•In total, eighteen different phenolic compounds were identified in rose hips.•A total of 52 volatile compounds were identified.•Fruits exhibited high levels of organic acids and phenolic acids.
Several active encapsulation technologies using polymeric matrix systems for food preservation have been developed in the last decade. In this study, the microencapsulation of rose hip seed oil (REO) ...in to a zein prolamine (ZP) fiber matrix via the coaxial electrospinning technique is studied. The morphological features of core-sheath REO encapsulated ZP fibers were modulated through process parameters (e.g. active and polymer solution concentration, applied voltage and media flow rate). The ZP solution concentration (outer needle) was found to be critical for REO loading capacity (LC) and encapsulation efficiency (EE). The optimal LC and EE of REO in ZP matrix was 12.24% and 90.16%, respectively, and were achieved using a ZP concentration of 35 w/v%. Food packaging potential was evaluated using peeled and segmented fruits (bananas and cumquats). The findings demonstrate a facile packaging route to improve food sustainability and reduce waste.
•Rose hip seed oil (REO) loaded into zein fibers using coaxial electrospinning.•Zein loading concentration affects the fiber size, morphology and hydrophilicity.•Zein concentration is crucial for loading capacity and encapsulation efficiency.•Bananas treated with fibrous REO/zein demonstrate most improved shelf-life.
The morphological and chemical characterization of Rosa sweginzowii Koehne fruit, which belongs to the Rosa section (formerly Cinnamomeae), as a source of valuable bioactive compounds is presented. ...The chemical composition of rose hips was evaluated in terms of the total content of anthocyanins (TAC), phenolics (TPC), and flavonoids (TFC) by spectrophotometry, and ellagic acid concentration by spectrofluorimetry (as borax complex). Morphology of fruit in macro- and microscale (by Scanning Electron Microscopy) and the presence of selected elements by Energy Dispersive X-Ray Spectroscopy were examined. The free ellagic acid content was found at a high level (16.101–24.465 mg/100g dw), and the one of total ellagic acid, after hydrolysis, was in the range of 20.244–29.771 mg/100g dw. Estimated TAC, TPC and TFC were 0.43–7.40 mg CGE/100g, 18 559–27 404 mg GAE/100g, and 10 293–14 159 mg CE/100g, respectively. Regarding the presence of valuable natural antioxidants in R. sweginzowii fruit, this plant could be used as functional food.

Ascorbic acid (vitamin C) is an important component in the fruits of dog rose. Its slightly laxative and diuretic effect, for which the dog rose is used in folk medicine, is supposed to be due to its ...content rich in pectin and organic acids. The investigated material were the fruits of Rosa canina L collected from 42 biotypes marked on the route: Suceava – Pătrăuţi – Lunca Sucevei (Dărmăneşti) - Costâna - Părhăuţi - Todireşti - Cajvana - Arbore - Solca - Clit - Marginea -Rădăuţi – Suceviţa – Palma during 2007, 2008, 2009 and 2010 years. The quantitative values of rainfalls influenced the content in vitamin C and the humidity of the fruits. The content in vitamin C increased with the increase in humidity and with the decease in temperature.
The dog rose area includes southern and central Europe, reaching southern Scandinavia; it is also found in Asia Minor, Central Asia and North Africa. In our country, Rosa canina is the most ...widespread of the many species of Rosa, common in all areas. The components of the station, known also as the „stationary factors” affect differently the plant life and their chemical composition. Cynosbati fructus is the false fruit of Rosa canina L. (Rosaceae), known in Romanian as rose hip. The rose hip contain as active ingredients 500-1000 % vitamin C, 600-10000 mg% carotenoids, pectin, dextrin, vitamins B2, E, PP, flavone, sugars, organic acids, tannins, volatile oil, vanillin, triterpenoid saponosides, beta-sitosterol, fat (lecithin, glycerides of fatty acids in seeds), minerals (potassium, calcium, magnesium, iron). Vitamin C (ascorbic acid) plays an important role in human body. The greatest amount is found in plants which reached maturity. It is concentrated in the rose hip flesh. Solutions easily destroyit in the presence of UV, of copper, silver, iron and oxidative enzymes traces. Vitamin C participates actively in all processes of oxidoreductions of the living cell. Its lack in food causes the disease called scurvy which manifests itself by inflammated and bleeding gums, tooth loss. Rose hip fruits are known as medicines since prehistoric times.

Eight types of tinctures were produced which differed regarding the raw material (rose hips) treatment i.e. seed content (with or without seeds) and the technique used for rose hip preservation, ...i.e.: fresh (without preservation), frozen, hot air-dried or freeze-dried. In produced tinctures the following parameters were determined: total phenolic content, polyphenolic composition by HPLC method, the contents of phenylpropanoids, flavonols, anthocyanins, l-ascorbic acid, dehydroascorbic acid, antioxidant activity against ABTS radical and ferric reducing antioxidant power (FRAP). The results indicate that generally higher extractability of the examined compounds was achieved in tinctures prepared from raw rose hip material without seeds. It was particularly pronounced for the content of selected phenolic compounds as well as ascorbic acid concentration. Removing seeds from rose hips affected also higher antioxidant activity in tinctures. Among all preservation techniques applied in this study, freeze-drying was the best to maintain high bioactive properties of the final product.
