Table 1.

Total phenolic and total flavan-3-ols determination in a commercial sample of U. tomentosa for defatting and non-defatting procedures.

Procedure	PT ^{1, 3, 4}	PRO ^{2, 3, 4}
Hexane and MeOH:H₂O ⁵	27.93 ^a ± 0.25	42.18 ^a ± 0.69
MeOH:H₂O ⁶	30.64 ^b ± 0.54	49.82 ^b ± 0.54

¹ mg of gallic acid equivalent/g extract. ² mg cyanidin chloride equivalents/g extract ³. Values are expressed as mean ± standard deviation (S.D.). ⁴ Different superscript letters in the same column indicate differences are significant at p < 0.05. ⁵ Extraction was performed with hexane and afterwards with 20% aqueous methanol (v/v). ⁶ Extraction was performed only with 20% aqueous methanol (v/v).
