Summary:
The method is used to determine 7 catechins plus caffein in green tea, extract and
dietary supplements containing green tea extract.
1. Does the applicability of
the method support the
applicability of the SMPR? If
not, please explain what is
missing.
No, the analytes Theobromin, theophyllin, theaflavins and theanin is missing. I guess
Theobromin and theophyllin could be detected with this method. For Theaflavins and
Theanin two different methods will be necessary
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.
yes
3. Are the definitions
specified in the SMPR used
and applied appropriately in
the method? If no, please
indicate how the terms are

written, contain all
appropriate precautions and
warnings related to the
method's reagents,
components, instrumentation,
or method steps that may be

reagent"
