The samples were collected from Batak area (Rhodope mountains, Bulgaria). The aim of this study was to perform analysis of the content of Fe, Zn, Mn, Cu, K, Na, Ca, P and Mg, fatty acid and phospholipids, in wild edible mushrooms Cantharellus cibarius . The samples were digested in a microwave closed system Multiwave 3000. ICP Optima model 7000 was used in determining the amount of elements in samples of mushrooms. The fatty acid composition was determined by gas chromatography. The phospholipid classes were isolated by a variety of two-dimensional TLC. Polar lipids were isolated from the total lipids by column chromatography. The average content of studied elements: Fe, Zn, Mn, Cu, K, Na, Ca, P and Mg in Cantharellus cibarius samples was: 82.295 mg kg-1, 78.829 mg kg-1, 18.319 mg kg-1, 27.568 mg kg-1, 31308.13 mg kg-1, 139.431 mg kg-1, 459.594 mg kg-1, 2713.615 mg kg-1 and 626.055 mg kg-1 . UFA prevailed in the mushroom oil (60.3%) and the content of MUFA was 35.4%. On the other hand, the amount of PUFA was lower (24.9%). The content of SFA was 39.7%. In the phospholipid fraction from mushrooms, PC (23%) predominated as a major component, followed by PA (21%). The quantities of PE and LPE in the phospholipid fraction were 5–6%.
