Influence of major components of essential oil from Chenopodium ambrosioides L. on the cellular oxygen consumption of Leishmania tarentolae promastigotes (LtP). Oxygen consumption of LtP (72–100 × 10⁶ cells/ml) was assessed by a Clark‐type electrode in air‐saturated medium containing 14.6 mM glucose. Increasing concentrations of compounds were added subsequently using DMSO as vehicle. At 1% DMSO (highest final concentration), O₂ consumption of LtP was inhibited by 1.74 ± 9.46%. Data are means ± standard deviation of four independent experiments. Asc = Ascaridole; Car = carvacrol; Caryo = caryophyllene oxide
