Table 2.

Cell viability of the fractions of T. peruviana fruit extract on prostate cancer cell line (HTB-81)

Fraction	% Viability
1	116 ± 3.7^a
2	121 ± 5^a
3	103 ± 4^a
4	3.71 ± 3.4^b
5	1.24 ± 1.9^b
6	62 ± 3^c

The fractions were obtained by flash chromatography. Viability was determined by MTT assay, values being expressed as mean ± SEM of triplicate determinations. Different letters represent statistically significant differences determined by one way ANOVA (ρ < 0.05), followed by Tukey’s multiple comparison test
