Abstract
|
|
|
|
Ochratoxin A (OTA), a mycotoxin classified as a potentially carcinogenic to humans, is slightly soluble in water. In this study, the transfer rate of OTA in herbal medicines to decoctions was investigated. Herbal medicine decoctions were prepared by boiling and autoclaving herbal medicines contaminated with OTA after soaking and not soaking in water. OTA amounts in decoctions and residues were analyzed using HPLC. Transfer of OTA (12.72-61.33%) from herbal medicines to decoctions was observed. Soaking and autoclaving steps enhanced the transfer rate of OTA to decoctions. The results meant that there is a potential risk for consumption of herbal medicine decoctions. Therefore, regular monitoring for mycotoxins, including OTA, in herbal medicines and proper management to ensure the safety of herbal medicines is necessary to protect consumers.
