Occurrence of ochratoxin A in Astragalus propinquus root and its transfer to decoction

Original language description

The aim of this study was to conduct a survey assessing the ochratoxin A (OTA) content in different samples of Astragalus propinquus root (AR), one of the fundamental herbs in Traditional Chinese Medicine, and the rate of OTA transfer to the most usable form as AR decoction used traditionally to reduce general weakness and increase overall vitality. The validated method of high-performance liquid chromatography with fluorescence detection (HPLC-FLD) was used for OTA determination in AR samples and AR decoctions. A limit of quantification was 0.35 ng/g. The recovery of the HPLC method for AR samples was 82 %. The relative standard deviation of repeatability was 2.6 %. All 40 tested AR samples were positive with values ranging from 28.8 to 1700.0 ng/g, with a mean value of 451.0 ng/g. OTA transfer into AR decoctions was 83.4 % ± 12.3 SD. Thus, it seems necessary to continue this OTA monitoring in AR and other herbal food supplements and estimate the actual human usual intake and health risk assessment.
