Determination of TPC, TFC, and the contents of three lignans in the beers
| Items | Beer A | Beer B | Beer C | Beer D |
|---|---|---|---|---|
| TPC (mg GAE/L) | 606.82 ± 16.64a | 575.00 ± 12.45b | 568.73 ± 13.57b | 519.09 ± 15.78c |
| TFC (mg QE/L) | 406.75 ± 4.05a | 377.19 ± 9.01b | 343.75 ± 7.23c | 303.19 ± 4.91d |
| Schisandrin (mg/L) | 12.10 ± 0.30a | 9.44 ± 0.20b | 8.96 ± 0.20c | UD |
| Gomisin A (mg/L) | 3.12 ± 0.10a | 2.20 ± 0.17b | 2.19 ± 00.11b | UD |
| Gomisin B (mg/L) | 0.86 ± 0.01a | 0.77 ± 0.05b | 0.65 ± 0.07c | UD |
Values are the means ± standard deviations of triplicate measurements. Means in a row that does not share the same alphabetical letter represent significant differences at p < 0.05
TPC total phenolic content, TFC total flavonoid content, UD undetected
