Türkiye’de satılan on diyet çay örneklerinin (n=10) fenolik bileşik içerikleri, yüksek performanslı sıvı kromatografisi (HPLC) sistemi ile belirlenmiştir. En çok bulunan fenolik bileşikler, gallik asit (ND-6.98 mg/100 g kuru numune), protokateşik asit (0.98-45.61 mg/100 g kuru numune), 4-hidroksibenzoik asit (ND-31.56 mg/100 g kuru numune), klorojenik asit (ND-0.73 mg/100 g kuru numune), kafeik asit (11.27-154.55 mg/100 g kuru numune), p-kumarik asit (ND-6.56 mg/100 g kuru numune), ferulik asit (ND–1.13 mg/100 g dw), ellajik asit (0.10-1.76 mg/100 g kuru numune), epikateşin (7.59-290.07 mg/100 g kuru numune), rutin (ND-49.95 mg/100 g kuru numune) ve kuersetindir (1.00 mg/100 g kuru numune). Elde edilen sonuçlara göre, hassasiyet ve doğruluk iyi bulunmuştur. Kalibrasyon eğrileri, tüm bileşikler için iyi bir doğrusallık göstermiştir (r2> 0.999). Diyet çay ürünlerinde tespit limiti, 0.010-0.050 μg/g arasında değişmiştir. Geri kazanımlar %86.45-97.35 aralığındadır. Bu çalışmada elde edilen sonuçların doğruluk ve tekrarlanabilirliklerinin iyi olduğu belirlenmiştir.

High performance liquid chromatography (HPLC) system was used to determine phenolic contents of dietetic tea samples (n=10) marketed in Turkey. The most abundant phenolic compounds were gallic acid (ND–6.98 mg/100 g dw), protocatechuic acid (0.98–45.61 mg/100 g dw), 4-hydroxybenzoic acid (ND–31.56 mg/100 g dw), chlorogenic acid (ND–0.73 mg/100 g dw), caffeic acid (11.27–154.55 mg/100 g dw), p-coumaric acid (ND–6.56 mg/100 g dw), ferulic acid (ND–1.13 mg/100 g dw), ellagic acid (0.10–1.76 mg/100 g dw), epicatechin (7.59–290.07 mg/100 g dw), rutin (ND–49.95 mg/100 g dw) and quercetin (1.15–10.50 mg/100 g dw). Based on the results of this study, sensitivity and accuracy were good. Calibration curves had a good linearity for all compounds (r2>0.999). The quantitation limit ranged 0.010 to 0.050 µg/g in dietetic tea products. Recoveries were in the range of 86.45-97.35%. Results had good accuracy and reproducibility.
