Antioxidant activity of sesame oil on oxidative stability of olive oil

In this study, the effects of blending sesame oil with olive oil at different concentrations (5%, 15% and 25%) and storing the oil blend at 60C for 30 days in relation to the physicochemical properties and fatty acid composition were determined. Peroxide value, free fatty acid, p-anisidine, K232 and K270 values were analyzed on the 15th and 30th days in olive oil as well as sesame/olive oil blend. After 15 days of storage, the lowest peroxide value (3.73 meq O2/kg) was obtained in olive oil containing 5% sesame oil, while olive oil containing 25% sesame oil has lowest peroxide value of 4.95 meq O2/kg after 30 days of storage. The lowest free fatty acid values were found in olive oils, with the values of 1.45% for 15th day and 1.67% for 30th day. The result revealed that peroxide and p-anisidine values increased, while the free fatty acid and ultraviolet absorption at 232 and 270 nm decreased during storage at 60C. Minimum free fatty acid (1.45%) was found in olive oil stored for 15 days, while the K values were in the range (0.01-0.02) following analysis on 30th day. This study revealed that addition of sesame oil to olive oil improved the antioxidative property of oil blends

The effect of fermentation process on bioactive properties, essential oil composition and phenolic constituents of raw fresh and fermented sea fennel (Crithmum maritimum L.) leaves

800-804The influence of fermentation on antioxidant activity, total phenol, total flavonoid and phenolic compounds of sea fennel and also volatile compounds of sea fennel essential oil was investigated and compared with fresh samples. Antioxidant activity, total fenolic and flavonoid contents decresed from 89.79 to 63.13%; from 259.58 to 77.92 mg/100 g; from 2114.67 to 390.50 mg/100 g, respectively. Twenty-six and thirty-three components of sea fennel oils were identified in raw and fermented sea fennel, accounting to about 99.99% and 99.44% of the total oil, respectively. The raw and fermented sea fennel leaves contained 22.31 and 1.32% sabinene, 12.08% and 7.45% limonene, 10.30% and 11.61% β-phellandrene, 8.59% and 9.17% (Z)-β-ocimene, 7.08% and 3.55% α-pinene, 28.36% and 42.05% γ-terpinene, 2.57% and 8.64% terpinene-4-ol, respectively. Dominant phenolic compounds were (+)-catechin, gallic acid, 3,4-dihydroxybenzoic acid and p-coumaric acid. Generally, all of the phenolic compounds reduced the effect of microorganisms during,. However, essential oil contents of sea fennel were not effected from fermentation process

The Effects of Oven Dehydration on Bioactive Compounds, Antioxidant Activity, Fatty Acids and Mineral Contents of Strawberry Tree Fruit

In this study, the effects of oven dehydration on chemical and bioactive properties, fatty acids, polyphenolic compounds and minerals of sandal strawberry tree fruit were investigated. While total carotenoid contents of the sandal strawberry tree fruit are determined between 4.20 (120 °C) and 5.43 µg/g (70 °C), tannin amounts of the sandal strawberry tree fruit were recorded between 5.13 (control) and 6.37% (70 and 120 °C). While total phenolic contents of dehydrated sandal strawberry tree fruit were found between 444.16 (120 °C) and 665.13 mgGAE/100 g (control), total flavonoid amounts of dehydrated sandal strawberry tree fruit were recorded between 592.91 (control) and 788.71 mg/100 g (120 °C). Antioxidant activity values of fruit ranged from 4.10 (120 °C) to 7.30 mmol TE/kg (control). Both total phenolic amounts and antioxidant activity values of untreated (control) sandal strawberry tree fruit were found to be higher than dehydrated ones, and a linear relationship was determined between the total phenolic amounts of the samples and their antioxidant activities. The highest amounts of phenolic compounds (ferulic acid, resveratrol and kaempferol) were detected in strawberry tree fruit dehydrated at 70 °C, followed by the control group and fruit dehydrated at 120 °C in decreasing order. Gallic acid, 3,4-dihydroxybenzoic acid, catechin, caffeic acid and rutin were the main constituents of the strawberry tree fruit, followed by syringic acid, p-coumaric acid and ferulic acid in descending order. Palmitic, stearic and oleic acid amounts of dehydrated strawberry tree fruit oils compared to the control were observed to increase with the applied temperature, while the contents of polyunsaturated fatty acids (linoleic and linolenic) decreased. In general, the mineral content of dehydrated strawberry tree fruit increased compared to the control. Since the oil, carotenoid, total phenol and phenolic component contents of sandalwood tree fruit are higher in the sample subjected to dehydration at 70 °C, this temperature can be considered as the ideal one for drying. In addition, considering the fatty acids, heat treatment at 120 °C can be preferred

CHANARIN-DORFMAN SENDROMLU ÇOCUK HASTAYA DENTAL TEDAVİ YAKLAŞIMI: OLGU SUNUMU

Chanarin-Dorfman Sendromu CDS , nadir görülen, otozomal ressesif genetik geçişli, iktiyozis ve multi sistem tutulumu ile karakterize bir lipid metabolizması hastalığıdır. Bu sendroma ait sınırlı sayıda kaynak bildirimi bulunmaktadır. Bu olgu sunumunda, diş ağrısı nedeniyle Ankara Üniversitesi Diş Hekimliği Fakültesi Pedodonti Anabilim Dalı’na başvuran 8 yaşındaki CDS’li hastanın diş tedavisi sırasında sendroma bağlı karşılaşılan problemlerin sunulması amaçlanmıştır. Hastanın ağız dışı muayenesinde, kafa derisi ve tüm vücutta eritem, deskuamasyon ve pullanma ile birlikte hastanın dudak kenarlarındaki çatlaklar nedeniyle ağzını açmakta zorlandığı gözlenmiştir. Hastanın ağız içi muayenesinde ise çok sayıda çürük varlığı 16, 26, 36, 46, 54, 55, 64, 65, 75, 84 ve 85 no’lu dişler tespit edilirken hastaya büyük azı keser hipomineralizasyonu BAKH teşhisi konulmuştur. Hastaya gerekli konservatif, cerrahi ve profilaktik tedaviler uygulanmış olup hareketli yer tutucu yapılmıştır. Literatürde söz konusu sendromla ilgili dental yaklaşıma ait hiçbir kaynağa rastlanmamış olup, CDS’li çocuk hastaların erken dönemde bir çocuk diş hekimine yönlendirilmesi ve koruyucu uygulamaların yapılması gerekliliği bir kez daha gözler önüne serilmektedi
