    (Scibulcom Ltd., 2017) Beyhan O.; Koc A.; Ercisli S.; Jurikova T.; Cakir O.
    Rose hips have been used as medicinal and aromatic plants for a long time throughout Turkey. The plant has been the focus of many recent studies due to its potential effects on treatment and prevention of several diseases. However, there are few in vitro studies concerning its composition and antioxidant capacity. The aim of the present study was to determine bioactive content including ascorbic acid, total phenolics, total flavonoids, total carotenoids and antioxidant activity of Rosa canina biotypes growing wild in Sivas province located eastern Anatolia. The results revealed that fruits of Rosa canina biotypes rich in terms of Vitamin C which ranged from 360 to 482 mg/100 g fresh weight base. The total phenolic content varied from 340 to 464 mg/100 g fresh weight. The biotype S-07 had the highest total flavonoids content (241 mg quercetin equivalent/100 g fresh weight) and the lowest value attributed to biotype S-01 as 151 mg/quercetin equivalent/100 g fresh weight. The antioxidant activity of the biotypes was between 14.2-30.7 ?g Trolox/ml sample. The results revealed that there was enough diversity among Rosa canina biotypes for bioactive content and promising biotypes with high bioactive content are ready material for future breeding activities.

    Biodiversity and Landscape Use of Sea Buckthorn (Hippophae rhamnoides L.) in the Coruh Valley of Turkey
    (Springer Verlag, 2015) Sezen I.; Ercisli S.; Cakir O.; Koc A.; Temim E.; Hadziabulic A.
    The Sea buckthorn, one of the most important wild edible fruits widely grown in Northeastern part of Turkey, is characterized by resistance to hard environmental conditions and looks spectacular, especially in autumn and winter when it is decorated with orange berries. Climatic conditions in Northern Anatolia are suitable for the growing of the Sea buckthorn, which can be encountered in various dry areas as well as by riversides. Local people traditionally processed or preserved sea buckthorn fruits (berries). The decorative sea buckthorn shrubs/trees and berries are an important element of natural landscape in Northeastern Anatolia. The aim of the study was to define the biodiversity among trees/shrubs, berries and leaves of the Sea buckthorn accessions based on morphological and biochemical data. Results showed a high diversity among accessions in terms of plant, leaf and berry characteristics. Berry diameter, length and 100 berry weight ranged from 5.48 to 7.18 mm; 6.64 to 9.14 mm and 15 to 26 g, respectively. A wide variability of berry skin colour was observed to be yellow, light yellow, dark yellow, yellow orange, orange and dark orange. The anthocyanin content varied from 7 to 38 mg/l berry juice. © 2014, Springer-Verlag Berlin Heidelberg.
