Based on data for DNP, DNP4-2, DNP2-1, DNP3-1, and DNP1-1 scavenging (%)

DPPH scavenging % (0.5 mg content): DNP4-2 > DNP > DNP2-1 > DNP3-1 > DNP1-1
DPPH scavenging % (1 mg content): DNP4-2 > DNP > DNP2-1 > DNP1-1 > DNP3-1

ABTS scavenging % (0.5 mg content): DNP4-2 > DNP > DNP3-1 > DNP2-1 > DNP1-1
ABTS scavenging % (1 mg content): DNP4-2 > DNP > DNP2-1 > DNP3-1 > DNP1-1

Hydroyl scavenging % (0.5 mg content): DNP > DNP4-2 > DNP2-1 > DNP3-1 > DNP1-1
Hydroyl scavenging % (1 mg content): DNP > DNP4-2 > DNP2-1 > DNP3-1 > DNP1-1

Up the table: it is shown that DPPH and ABTS free radical scavenging (%) of DNP4-2 are better than other compounds; however, the hydroxyl free radical scavenging (%) of DNP is better than other compounds.
