The antioxidant IC50 values of compounds and the correlations between contents and IC50 values of extracts.
| Materials | Multiple Regression Equations 2 | IC50 Value(mM) |
|---|---|---|
| Lophatherum gracile | Y = 8.413 − 21.269 XORI + 104.946 XCYN − 383.105 XAPI | 5.07 ± 0.26 |
| Phyllostachys nigra | Y = 2.272 − 1.673 XORI | 3.25 ± 0.23 |
| Pleioblastus amarus | Y = 3.279 − 3.855 Xiso-ORI + 1.468 XTotal | 1.98 ± 0.06 |
2 Y refers to IC50 values of an extract to scavenging DPPH free radical, and X means the content of a compound or the total content of seven characteristic compounds.
