摘要
In this study, 22 species of medicinal plants (anise, centaury, chamomile, fennel, flax, green tea, indian hemp, laurel, licorice, linden, marestail, melissa, nettle, oat, red clover, riesenfenchel, rosehip, rosemary, sage, senna tea, yam, yarrow) were taken from five different local herbalists in Hatay. Chromium concentrations were determined by inductively coupled plasma-atomic emission spectroscopy. The highest chromium concentrations were detected in chamomile (4.21 +/- 0.18 mg kg(-1)), licorice (2.80 +/- 0.12 mg kg(-1)), melissa (2.71 +/- 0.10 mg kg(-1)), marestail (2.66 +/- 0.10 mg kg(-1)), and anise (1.98 +/- 0.06 mg kg(-1)). Minimal concentrations of chromium were found in riesenfenchel (0.33 +/- 0.01 mg kg(-1)), red clover (0.37 +/- 0.01 mg kg(-1)), centaury (0.43 +/- 0.01 mg kg(-1)), senna tea (0.49 +/- 0.01 mg kg(-1)), and linden (0.50 +/- 0.01 mg kg(-1)). Cr(III) and Cr(VI) concentrations in medicinal herbs were found in the range of 0.26-3.12 mg kg(-1) and 0.07-1.09 mg kg(-1), respectively.
