From the resinous exudates of Heliotropium sinuatum have been isolated and characterized eight flavonoids. In this paper we show the bacteride activity of resin and previously isolated flavonoids. Kinetics of bacterial growth gave the generation time of bacterial population. This method let it knew a quantitative approach of the antibacterial capacity of resins and flavonoids. A discussion of the effect of flavonoids class and type of substituents is developed
