Anthelmintic Activity of Crude Extract and Essential Oil of Tanacetum vulgare (Asteraceae) against Adult Worms of Schistosoma mansoni
Figure 2
In vitro effect of the crude hydroalcoholic extract of T. vulgare (TV) on the viability of the S. mansoni adult worms. Pairs of adult worms were treated with TV at 200 μg/mL during 120 h and the viability was measured by MTT assay at 550 nm. RPMI 1640 medium and 0.5% DMSO in RPMI 1640 medium were used as negative control groups. Heat-killed worms at 56°C (dead) were used as positive control group. The viability was expressed as mean of the absorbance values from three experiments. *Significantly different from control (); significantly different from dead group ().
