AB  - The study aimed to examine the external validity of the Folate Food Frequency Questionnaire (F-FFQ) designed for assessing the folate intake in Serbian women of reproductive age. The F-FFQ was tested against repeated 24 h dietary recalls and correspondent nutritional biomarkers (red blood cells (RBC) and serum folate concentrations) using the method of triads. In a cross sectional study, 503 women aged 18-49 years completed dietary questionnaires and representative validation subsample (n = 50) provided fasting blood samples for biomarker analyses. Correlation coefficients were calculated between each of the dietary methods and three pair-wise correlations were applied for the calculation of validity coefficients. Correlation coefficients observed between F-FFQ and three 24 h recalls were r = 0.56 (p  lt  0.001) and r = 0.57 ( p  lt  0.001) for total sample and validation group, respectively. Bland-Altman plot and cross-classification analyses indicated good agreement between methods. High validity coefficients were determined between the true intake (I) and dietary assessment methods, F-FFQ (Q) and 24 h dietary recalls (R) (rho QI(rbc) = 0.871 and rho QI(ser) = 0.814; rho RIrbc = 0.652 and rho RIser = 0.698), and moderate ones for biomarkers (B) (rho BIrbc = 0.428 and rho BIser = 0.421). The F-FFQ is valid instrument for the assessment of dietary folate intake in women living in Serbia, a country without mandatory folic acid food fortification.

AB  - Background/Aim. The beneficial effects of medicinal plants are well-known from the ancient times. However, expansion of phytopharmacy and phytotherapy occured during the last decades. Medicinal plants can absorb environmental contaminants from the ground and consequently may cause harmful effects on human health. Quality control usually comprises standard methodology which includes macroscopic identification and examination of active ingredients. Additionaly, there is a permanent need to control the level of pollutants in herbs, with a particular attention to the level of toxic metals. In this study we estimated the level of contamination by determining the content of cadmium (Cd) in the herbs of Hypericum perforatum and Thymus serpyllum collected from the different localities of the mountains Rtanj and Ozren. Methods. Herbs of investigated plants were collected during July 2005 from various localities of Rtanj and Ozren mountains. After drying, homogenization and mineralization, Cd content was determined by atomic absorption spectrophotometry. Results. The obtained results show that Cd content varies significantly in Hypericum perforatum samples collected. The lowest Cd level was found in samples from the one of Rtanj localities (0.25 mg Cd/kg), while the highest was observed in Hypericum perforatum from Ozren locality (1.24 mg/kg). Levels of Cd in the three of four investigated localities were higher than pro posed by WHO (0.3 mg/kg dried herb material). In all investigated samples of Thymus serpyllum herbs Cd levels were below the limit of detection of analytical method (0.2 mg Cd/kg dried materials). Conclusion. This work contributes to the issue of Cd content in Hypericum perforatum and Thymus serpyllum grown in localities of Rtanj and Ozren, and implies the importance for systemic control of Cd content in Hypericum species in order to provide safety of their preparations. Furthermore, regarding Cd toxicity, maximal permissible level of Cd in plant material should be evaluated and established concerning national legislative frame.
AB  - Uvod/Cilj. Lekovitost nekih biljnih vrsta bila je poznata čoveku još pre naše ere. Međutim, do ekspanzije fitofarmacije i fitoterapije dolazi tek poslednjih decenija. Lekovite biljke usled zagađenja životne sredine mogu da apsorbuju prisutne zagađivače. Kvalitet biljnih sirovina prati se standardnim metodama koje se prvenstveno odnose na identifikaciju biljne vrste i ispitivanja aktivnih principa. Ipak, i pored toga, uočena je potreba za kontrolisanjem i praćenjem nivoa zagađivača, među kojima značajno mesto zauzimaju toksični metali. U ovom radu ispitivan je sadržaj kadmijuma (Cd) u herbi dve biljne vrste, Hypericum perforatum L. i Thymus serpyllum L. koje su prikupljene sa različitih lokaliteta planina Rtanj i Ozren, sa ciljem procene nivoa kontaminacije. Metode. Herbe ispitivanih lekovitih biljaka sakupljene su tokom jula 2005. godine sa različitih lokaliteta planina Rtnja i Ozrena. Nakon sušenja, homogenizacije i mineralizacije, sadržaj Cd određivan je metodom atomske apsorpcione spektrofotometrije. Rezultati. Dobijeni rezultati ukazali su na značajne varijacije sadržaja Cd u sakupljenim uzorcima Hypericum perforatum. Najniži sadržaj Cd od 0,25 mg Cd/kg dobijen je u uzorku sa lokaliteta Rtnja, dok je najviši nivo Cd određen u uzorku Hypericum perforatum sa lokaliteta Ozrena (1,24 mg/kg). Dobijene vrednosti sadržaja Cd u herbi Hypericum perforatum sa tri od četiri ispitivana lokaliteta bile su iznad vrednosti koju preporučuje SZO (0,3 mg/kg osušene droge). U svim ispitivanim uzorcima Thymus serpyllum nivoi Cd bili su ispod nivoa detekcije primenjene analitičke tehnike (0,2 mg Cd/kg osušene herbe). Zaključak. Rezultati ovog rada doprineli su istraživanju sadržaja Cd u biljnim vrstama Hypericum perforatum i Thymus serpyllum koje rastu na lokalitetima Rtnja i Ozrena i ukazuju na potrebu uvođenja sistematske kontrole sadržaja Cd u Hypericum vrstama radi bezbedne upotrebe preparata izrađenih na bazi ovih biljnih vrsta. Imajući u vidu toksičnost Cd nameće se potreba da se nacionalnim zakonodavstvom odrede i ustanove maksimalno dozvoljene koncentracije sadržaja ovog metala u biljnim lekovitim sirovinama.
