Table 4. Total Phenolic Contents of MSX Samples and Their DPPH Free Radical Scavenging Activities.
| sample | total phenolic content of MSXa (mg/100 g of gallic acid equivalents) | total phenolic content of MSX–EtOAc (mg/100 g of gallic acid equivalents) | DPPH free radical scavenging activity of MSXa,b (IC50, μg/mL) |
|---|---|---|---|
| MSX-1 | 16648.15 | 26278.28 | 97.6 ± 4.73 |
| MSX-2 | 16337.83 | 27441.33 | 102.4 ± 7.25 |
a
Assay conducted with neat samples of original MSX samples.
b
Positive controls, ascorbic acid and BHT, have IC50 values of 40 and 3000 μM, respectively.5
