Abstract

The essential oil of Rheum ribes L. stalks and flowers, growing in Iran, were extracted with hydro-distillation and analyzed by GC-MS. Thirty constituents representing 93.84% of Rheum oil were identified. The oil was found to be rich in hydrocarbons especially long-chain n-alkanes (80.81%). The most abundant components in the oil included tricosane (26.29%), heneicosane (26.07%), pentacosane (10.63%), heptacosane (10.37%) and palmitic acid (3.64%). The essential oil was also evaluated for general toxicity bioassay using brine shrimp lethality method. The toxicity profile of the oil indicated some degree of toxicity in comparison with podophyllotoxin.
