Table 3.
Anthocyanin content expressed as mg per capsule, tablet, or teaspoon (5 g) ranging from none detected to 38.22 mg (BL8). Only samples found to contain the Vaccinium fruit listed on package labeling (see Table 1) and were clearly distinguishable by high‐performance liquid chromatography (HPLC) data are presented here (n = 27)
| Vaccinium fruit | Total samples evaluated | Number of adulterated and not included in quantificationa | Number of nonadulterated samples quantified | Mean (standard error) | Minimum ACYa | Maximum ACY |
|---|---|---|---|---|---|---|
| Cranberry | 20 | 3 | 17 | 2.47 (0.63) | 0.04 | 14.37 |
| Lingonberry | 2 | 2 | 0 | b | b | b |
| Bilberry | 15 | 10 | 5 | 5.23 (1.22) | 2.15 | 8.43 |
| Blueberry | 8 | 3 | 5 | 1.41 (0.63) | 0.60 | 2.23 |
a
Not included in the quantification data here due to absence of anthocyanin, too degraded, suspect profiles, or contained additional fruit (two bilberry samples and one blueberry sample) ingredients.
b
Not determined.
