Antioxidant Properties of Crude Extract, Partition Extract, and Fermented Medium of Dendrobium sabin Flower

Figure 2

Antioxidant capacity assays (DPPH, ABTS, and FRAP) between partition extracts. The DPPH, ABTS, and FRAP results are presented as mean ± SD. Post hoc (Tukey’s) test shows significant difference in all DPPH, ABTS, and FRAP assays between ethyl acetate extract (EA 100; EA A) with water layer extract (W 100; W A) and hexane extract (H 100; H A) at , respectively. In FRAP assay, water layer extracts (W 100 and W A) are also significantly different from hexane layer extracts (H 100 and H A) at , respectively. refers to value < 0.001.
