In strengthening the immune system, demand for natural products is increased rather than preferring food supplements and medicines. Instead of well-known, there are many hidden, valuable, naturally grown in own flora contents only appreciated by local people and utilized as traditional treatments. Medlar leaves are used for antioxidant, diuretic and diabetic properties as one this contents. For pointing the lights on it, antioxidant capacity of extractable, hydrolysable and bioaccessible extractions were evaluated in terms of TEACABTS and TEACDPPH as a scope of this study. Samples were obtained from Yenicaga, Bolu from West Blacksea side of Turkey. Bioaccessible phenolics were determined as 37.41-43.84 µmol Trolox/g for TEACABTS and 130.26-145.79 µmol Trolox/g for TEACDPPH. %Bioaccessibility was % 31.43-39.78 over the extractable and hydrolysable fraction. This study was aimed be a clue for the bioactive potential of the medlar leaf and it should be revealed as bioactive contents with their provided effects for leaves on health in detail with further studies.
