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