Values are expressed as means±SD (n=3).
NC, Tteokgalbi without Cissus quadrangularis powder (C); PC, Tteokgalbi treated with 0.10% ascorbic acid as a positive reference; C1, Tteokgalbi treated with 1.00% C; C2, Tteokgalbi treated with 2.00% C; C3, Tteokgalbi treated with 4.00% C.
Values with different superscript within the same column differ significantly by Tukey’s multiple range test (p<0.05).
Values with different superscript within the same row differ significantly by Tukey’s multiple range test (p<0.05).
GAE, gallic acid equivalent; QE, quercetin equivalent; LLOQ, lower limit of quantification.
