OPTIMIZATION OF EXTRACTION PARAMETERS FOR FAT SOLUBLE VITAMINS AND MAJOR ELEMENT ANALYSIS IN POLYGONUM COGNATUM MEISSN PLANT (MADIMAK)
The concentrations of fat soluble vitamins (A and E) and various metal ions (Ca, Cd, Cr, Co, Cu, Fe, Mg, Mn, Pb, Zn) have been determined in Polygonum cognatum Meissn plant samples collected from Sivas, Turkey. Analysis of vitamins were carried out by HPLC after Soxhlet extraction and metal ions were determined by FAAS after microwave digestion, respectively. The reliability of results were confirmed by recovery experiments in spiked samples. Recovery values were calculated in the range of 96 % and 105% while relative standard deviations (RSD) were in the range of 1.7 % and 8.5 %. The contents of vitamin E in plant samples were determined as 63.008±4.548 mg kg-1 and 59.178±5.142 mg kg-1. The amount of essential metals such as Mn, Zn, Fe were higher than most of common edible plants and the concentrations of toxic metals were lower than critical limits.
