Fig. 2From: Antiviral effect of compounds derived from the seeds of Mammea americana and Tabernaemontana cymosa on Dengue and Chikungunya virus infectionsEvaluation of compound cytotoxicity in VERO cells. Each compound was evaluated by MTT at concentrations from 6.25 μg/mL to 400 μg/mL and compared with the untreated controls. a Compounds extracted from the seeds of M. americana. b Compounds extracted from the seeds of T. cymosa. *Only coumarin B significantly decreased the cellular viability at a concentration of 400 μg/mL (ANOVA-LSD, p < 0.05)Back to article page
