The purpose of this research was to find out the substance which deactivate α-Amanitin Toxicity

The materials and methods used in the study include analysis with high performance liquid chromatography (HPLC) to:

1.Demonstrate the standard α-amanitin at concentrations of 25, 50 and 100 μg/ml

2.Determine the deactivation of α-amanitin with 1) 18% acetic acid 2), calcium hydroxide 40 mg/ml, 3) potassium permanganate 20 mg/ml, 4) sodium bicarbonate 20 mg/ml

3.Report the statistical analysis as the mean ± standard deviation (SD) and paired t-test.

The result revealed that potassium permanganate could eliminate 100 percent of the α-amanitin at 25, 50 and 100 μg/ml. Calcium hydroxide, sodium bicarbonate and acetic acid had lower elimination rates at those concentrations: 68.43 ± 2.58 (-71.4, -67.2, -66.7%), 21.48 ± 10.23 (-29.4, -25.2, -9.9%) and 3.21 ± 0.02% (-3.2, -3.2, +1.1%), respectively. The conclusion of this study was suggested that potassium permanganate could be applied as an absorbent substance during gastric lavage in patients with mushroom poisoning. It also might be effective as a cleansing wash for uncooked mushrooms. Investigation of potassium permanganate’s ability to absorb α-amanitin in animal models and humans should be considered. .
