Summary:

This method determines the content of catechins and the methyl xanthine, caffeine, in tea (Camillia sinensis) raw materials, extracts and dietary supplement products using HPLC with a phenyl column and UV detection. The method is presented as the published JAOAC paper.

1. Does the applicability of the method support the applicability of the SMPR? If not, please explain what is missing. 2. Does the analytical technique(s) used in the method meet the SMPR? If not, please specify how it differs from what is stated in the SMPR. 3. Are the definitions specified in the SMPR used and applied appropriately in the method? If no, please indicate how the terms are used. 4. Does the method, as written, contain all appropriate precautions and warnings related to the method's reagents, components, instrumentation, or method steps that may be hazardous? If no, please suggest wording or option(s).

Yes.

Yes.

Yes, although the method outlined in the journal reference appears to have been written before the SMPR was adopted.

No. In that this is a journal publication, the precautions are not stated in that they represent general precautions needed for reverse phase HPLC and for the typical solvents and reagents used.
