Antioxidant characteristics of leaves, twigs, and acorns from two Serbian oak species Quercus robur L. and Quercus petraea L. from Vojvodina province (northern Serbia) were investigated. 80% ethanol (in water) extracts were used for antiradical power (ARP) determinations against DPPH center dot, (NO)-N-center dot, and O-2(center dot-) radicals, ferric reducing antioxidant power (FRAP), total phenol, tannin, flavonoid, and proanthocyanidin contents. Permanganate reducing antioxidant capacity (PRAC) was determined using water extracts. Beside, mentioned parameters, soluble proteins, lipid peroxidation (LP), pigments and proline contents were also determined. The data of different procedures were compared and analyzed by multivariate techniques (correlation matrix calculation and principal component analysis (PCA)). PCA found that investigated organs of two different oak tree species possess similar antioxidant characteristics. The superior antioxidant characteristics showed oak leaves over twigs and acorns and seem to be promising source of antioxidants with possible use in industry and pharmacy.

The prevalence of chronic diarrhoea has been estimated at 4-5% in Western populations and is one of the most common reasons for referral to a gastroenterological clinic. Investigation of patients was rationalized in 2003 with the publication by the British Society of Gastroenterology of guidelines for the investigation of chronic diarrhoea.(1) The guidelines may also be viewed at www.bsg.org.uk/clinical_prac/guidelines/chronic_diarr.htm.
