Abstract

     Atractyloside (ATR) is a diterpenoid glycoside that occurs naturally in various plants. Consumption of plants containing ATR has caused fatal intoxications. A high performance liquid chromatography (HPLC) method was used for the identification and determination of ATR. The analysis was performed on C8 column utilising a gradient elution profile. The eluant was water-acetonitrile gradient, in the presence of trifluoroacetic acid (0.05%), and at a flow rate of 1.0 ml/min and UV detection at 210 nm. The method showed to be linear (r2 > 0.99) and precise (R.S.D < 5 %). The detection and quantification limits were 2µg/ml and 12.5µg/ml respectively. This method was used in the quantification of various aqueous extracts of Atractylis gummifera L. roots. ATR concentration was found between 2.9 and 4.3 mg/ml according to the region and the season of harvest.
