Seeking information on a standard method extraction ochratoxin A for TLC.
Sinc you will use TLC, you will need very specific sample clearnup like affinity column.
Which material will you analysis?
Green coffee
See my previouse post above, it is exactly what you need.
Thank you Mr Narong Chamkasem
I send you further informations for OTA extraction to TLC determination:
1.
An older approach

2.
A current approach
see attachment
Best regards
Thank you Mr Vladimir Ostry
