Rosehip, Rosa canina L. fruit, is valued for its flavor, taste, color and aroma, in accordance with its recognition as one of richest sources of pro-health compounds. Screening, preservation and propagation of the most valuable local populations of rosehip are performed for food, pharmacological, and cosmetic applications. Eleven native R. canina genotypes from the Interior Aegean region, Turkey, were collected and analyzed regarding organic acids, phenolic compounds, sugars, and DPPH scavenging activity within this study. Regarding biochemical profile of fruits, protocatechuic acid and quercitrin were the most dominant compounds among 12 identified phenolics. The dominant organic acids were malic and citric and fructose and glucose
Tree, leaf, pod and seed morphology, as well as pod biochemistry of 36 wild-grown carob genotypes sampled from rural areas in Marmaris district located at western Turkey, were investigated. Leaf and pod dimensions, pod and seed weight, seed ratio, pod and seed colour and shape and surface traits were investigated. Soluble solid content (SSC), titratable acidity, vitamin C and protein and dietary fibre contents were also detected. Results showed significant differences for all quantitative traits, although differences are more pronounced for some pod (weight, width, length and thickness) and seed characteristics (weight, dimensions and ratio). Pod and seed colour, shape and surface qualitative threats were found to be quite variable among genotypes. The majority of genotypes had an open tree growth habit. Leaf length and width were found to be between 8.04 cm (M19) and 11.60 cm (M12) and 8.40 cm (M2) and 12.04 cm (M12) among genotypes. Pod weight ranged from 8.3 g (M35) to 29.5 g (M3) in the wild genotypes. The average pod dimensions (width, length and thickness) were between 14.27 and 23.38 mm, 12.54 and 21.67 cm and 4.80 and 8.37 mm, respectively. The SSC ranged from 49.36 to 69.36% in the pods of wild carob genotypes. The results of this study indicate a good genetic resource potential of Turkish wild carob populations for future breeding programmes.
The present work aimed the study of rutin, protocatechuic, catechin, p-hydroxy benzoic, chlorogenic, caffeic, kuersetin, luteolin, kamferol, p-coumaric, vanilin and ferulic acids composition in different currant varieties in Turkey. Red and black currant varieties (Goliath, Red Lake, Rovada, Rosenthal, and Booskop Giant) were analyzed for phenolic acids by using reversed-phase high performance liquid chromatography (HPLC). Results showed that p-coumaric acid (1.66-0.04 μg g-1) was the predominant phenolic acid extracted from currant varieties. In addition, other acids, namely rutin (35.41-7.23 μg g-1), Protocatechuic (3.28-2.84 μg g-1), Chlorogenic (65.49-2.38 μg g-1), and kuersetin acids (2.29-1.50 μg g-1) were obtained in extracts from currant fruit.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
