Table 2.

Extractive yield (EY) and total phenolic content (TPC) of methanol/water/acetic acid (49.5:49.5:1) extracts of Salix atrocinerea Brot., Salix fragilis L., and Salix viminalis L. barks.

Salix spp.	EY (% of Dry Bark, w/w)	TPC (g GAE kg⁻¹ of Dry Bark)	TPC (mg GAE g⁻¹ of Extract)
Salix atrocinerea Brot.	15.1 ± 1.7 ^b	44.47 ± 6.68 ^b	293.36 ± 19.52 ^b
Salix fragilis L.	9.7 ± 0.3 ^a	17.47 ± 3.19 ^a	179.06 ± 30.64 ^a
Salix viminalis L.	10.1 ± 0.8 ^a	24.76 ± 0.82 ^a	246.44 ± 16.58 ^a,b

The results represent the mean ± standard deviation. Means with different superscript minor case letters (a, b) within the same column are statistically different (one-way ANOVA, followed by Tukey’s HSD test, p < 0.05). GAE, gallic acid equivalents.
