AB - Injury to the peripheral nerve may lead to deficits in nerve function. An increase in the levels of free radicals plays a role in inhibition of nerve regeneration following damage. The aim of this study was to investigate the effects of lotus essential oil (LEO) on neurite outgrowth in vitro and nerve regeneration in vivo in a rat model of sciatic nerve crush injury. Gas chromatography‑mass spectrometry analysis showed that the principal constituent of LEO was palmitic acid ethyl ester (25.12%). The radical scavenging activity of LEO was evaluated using the DPPH method, and was determined to be IC50=29.01±2.93 µg/ml. LEO‑treated sensory neurons exhibited increased neurite outgrowth and upregulated levels of phospho‑ERK. Sensory and motor functions were improved in rats treated with 50 and 100 mg/kg LEO, and this was accompanied by an increase in the number of neurons in the dorsal root ganglia, as well as an increase in the nerve axon diameters following nerve injury. Taken together, these results suggests that LEO may serve as a novel pharmacological option for the management of peripheral nerve injury.
