II. Review of the Method Only 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). III. Review of Supporting Information 1. Are the definitions specified in the SMPR used and applied appropriately in the supporting documentation (manuscripts, method studies, etc...)? If not, please explain the differences and if the method is impacted by the difference.

Yes. The SMPRs indicated that the method will be able to quantify proanthocyanidin present in cranberry in ONE or MORE of the following: fruit, juice, beverage, dried cranberry fruit, cranberry sauice, ingredients, or dietary supplements. The proposed method was reported to be applied to cranberry powders and juices. I think that it will be of interest to apply the method to the other matrices indicated in the SMPRs.
