Yüksek Saflıkta Beta Amanitin Üretimi.

Objective: Beta amanitin has been used in experiment and has been purified only around 90% purity using existing methods. In this study, it has been aimed to describe the method in order to produce high-purity beta amanitin using preparative HPLC. Methods: Amanita phalloides mushrooms hve been collected, extracted and purified 2 times using preparative HPLC. Validation of the toxin has been performed by comparison of retention time at HPLC and ultraviolet spectrum. Results: Beta amanitin was obtained with 91% (±2.36) purity after first purification process. Beta amanitin was obtained with 99,2% (±0.38) purity after second purification process. It seemed that purified toxin and standard were given maximum absorbance at 303 nm and minumum absorbans at 263 nm, and the structure of the spectrums for both was similar. Conclusion: Beta amanitin with >%99 purity can be produced by this method. [ABSTRACT FROM AUTHOR]
