Grapevine (Vitis vinifera L.) is regarded as one of the world’s most important fruit crops in terms of acreage and commercial worth. Grapes are used to make not only wine but also fresh fruit, dried fruit, and juice. The quality of grapes or wine is significantly affected by environmental factors such as altitude, soil type, and climate. In this study, the 5 white grape varieties (Ağın beyazı, Tahannebi, Kabarcık, Şilfoni, and Besni) grown at different altitudes (800 m, 1000 m and 1200 m) in Turkey were investigated for their vitamin, and phytosterol concentrations as well as lipid peroxidation content. Şilfoni grape harvested at 800 m was found to possess the lowest lipid peroxidation content. High altitudes, were found to reduce lipid peroxidation contents in the Ağın beyazı, Tahannebi, and Kabarcık strains. The highest stigmasterol (98.34 μg/g), and beta-sitosterol (86.90 μg/g) concentrations were found within Şilfoni grape variety harvested at 800 m. The highest vitamin D-2 and D-3 levels were found in Ağın beyazı (1.39 μg/g) and Kabarcık (4.13 μg/g) grape varieties, both harvested at 1200 m. Kabarcık grape, however, revealed the highest concentrations of R-tocopherol (63.09 μg/g) and alpha-tocopherol (24.13 μg/g) at 1200 m within the samples. The highest vitamin K-2 level was determined within the Tahannebi grape (15.44 μg/g) from 1200 m. It was observed that the vitamin and phytosterol concentrations of white grape varieties tended to increase, while the lipid peroxidation values tended to decrease at high altitudes, especially at 1200 m. This study also exhibited a strong relationship among Vitamin D3, R-tocopherol, and alpha-tocopherol in the studied white grape cultivars.

This study aimed to investigate the protective effects of arbutin (ARB) against brain injury induced in rats with potassium bromate (KBrO3). The rats were divided into four groups as Group 1: Control (0.9% NaCl ml/kg/day p.), Group 2: KBrO3 (100 mg/kg (gavage), Group 3: ARB (50 mg/kg/day p.), and Group 4: KBrO3 + ARB (100 mg/kg (gavage) + 50 mg/kg/day p.). At the end of the fifth day of the study, the rats in all groups were killed, and their brain tissues were collected. In the collected brain tissues, malondialdehyde (MDA), superoxide dismutase (SOD), and catalase (CAT) levels were measured, and routine histopathological examinations were made. The MDA levels in the group that was exposed to KBrO3 were significantly higher than those in the control group (p ˂ 0.001). In comparison to the KBrO3 group, the MDA levels in the KBrO3 + ARB group were significantly lower (p ˂ 0.001). It was observed that SOD and CAT enzyme activity levels were significantly lower in the KBrO3 group compared to the control group (p ˂ 0.001), while these levels were significantly higher in the KBrO3 + ARB group than in the KBrO3 group (p ˂ 0.001). Additionally, the group that was subjected to KBrO3 toxicity, as well as ARB administration, had much lower levels of histopathologic signs than the group that was subjected to KBrO3 toxicity only. Consequently, it was found that KBrO3 exposure led to injury in the brain tissues of the rats, and using ARB was effective in preventing this injury.

It has been proven that grapes, which are widely cultivated around the world, have positive health effects. However, the phytochemical composition of lesser-known local varieties of Vitis vinifera L., which has a very wide range of varieties, is still being studied. The aim of this study was to determine the effects of skin color and ripening time on the phytochemical compositions of grape seeds. As a plant material local grape varieties cultivated in Southeastern Anatolia (Turkey) were used. The results showed that grape skin color has an effect on vitamin K1, vitamin K2, vitamin D3, δ‑tocopherol, stigmasterol, ergosterol, myristic acid, oleic acid, trans-elaidic acid, and the monounsaturated fatty acid (MUFA) and saturated fatty acid (SFA) contents of seeds. The seeds of grape varieties with colored skins were richer in K2, D3, stigmasterol, oleic acid, trans-elaidic acid, and MUFAs, while the seeds of grape varieties with white skins were richer in K1, δ‑tocopherol, ergosterol, and SFAs. The ripening time of the grapes was found to have a partial effect on the fatty acid compositions of the seeds, but without any effect on linoleic acid contents. As the ripening time was delayed, there was an increase in oleic acid and MUFA contents of the seeds, while there was a decrease in SFA contents. In general, increased vitamin K1 contents of the seeds were parallel to decreases in vitamins K2, D2, and D3, as well as α‑tocopherol content and antioxidant activity. The seeds of grape varieties that have colored skins were found to have more suitable compound compositions for use in the production of functional foods that support human and animal health. In addition, it was concluded that grape berries that ripen late may be more favorable for grapeseed oil production.

This study investigated the concentrations of some accumulated trace metals (iron, manganese, zinc and copper) and fatty acids in liver and muscle tissues of mirror and scaly carp varieties (Cyprinus carpio L., 1758) living in Keban Dam Reservoir (Elazig), which is the second-largest artificial lake in Turkey that hosts commercially valuable and preferred fish varieties for human consumption. The inductively coupled plasma mass spectrometry (ICP-MS) method was used to analyse the concentrations of trace elements. Fatty acid levels were measured in a gas chromatography mass spectrometry (GC–MS) device, using a flame ionization detector (FID). Considering the two fish varieties and tissues that were studied, the mean metal concentrations (μg g−1) were found in the following ranges: Fe 12.32–49.97, Mn 0.12–0.62, Zn 10.45–86.59 and Cu 2.74–11.86. Although the lowest levels were detected in the muscle tissue for all the metals examined, the levels in the liver tissue were significantly higher. According to the results of the analyses on fatty acid concentrations, the mean total saturated fatty acid levels in the muscle tissue of the scaly carp and mirror carp varieties were found to be 31.07 and 31.43 (%), respectively, whereas these values for the liver tissue were consecutively 22.36 and 22.08 (%). Successively, the mean total levels of unsaturated fatty acids were determined as 68.93 and 68.40 (%) in the muscle tissue and 77.64 and 77.92 in the liver tissue. This study, with the finding that the trace (metallic) element accumulation rates were below the upper limits of the tolerable range, and the examined fish varieties were rich in fatty acids, shows that mirror carp and scaly carp living in Keban Dam Reservoir are highly nutritious for human diets.
