Antiviral and Antioxidant Activities of Sulfated Galactomannans from Plants of Caatinga Biome

Table 1

Sulfate yield (%) of galactomanans and inhibition concentration (IC₅₀) of DPPH.

Galactomannans	Sulfate yield (%)	DS	IC50 (g/mL) ± SD
A. pavonina	33.9 ± 0.6^a	0.72 ± 0.04^a	7.51 ± 0.03^a
D. gardneriana	35.7 ± 0.1^b	0.75 ± 0.02^a	7.56 ± 0.04^a
C. ferrea	39.0 ± 0.3^c	0.82 ± 0.01^b	0.94 ± 0.01^b
Vitamin C	—	—	0.48 ± 0.01^b

Different letters mean significant differences within the lines. IC₅₀ means ± standard deviation (SD). DS: sulfating degree.
