I. Summary of the Method

Cranberry extract powder, cranberry juice concentrate, or cranberry capsules are extracted with methanol, reacted with DMAC and quantified against a standard curve of Procyanidin A2 using UV/VIS with kinetic reaction at 610 nm.

II. Review of the Method Only:

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.

Based on the reported data the method was performed on extract, juice concentrate, and capsules. The method was not tested on other types of the cranberry supplements. However, the method seems to be applicable to the stated matrices but there is no indication how it compares to LC-MS or HPLC data.
