Abstract


Background: Nymphaea lotus Linn. (Nymphaeaceae), commonly known as white water-lily, white lotus or Egyptian lotus, is an important and well-known medicinal plant, widely used in the Ayurveda and Siddha systems of medicine for the treatment of diabetes, inflammation, liver disorders, urinary disorders, fever, skin diseases, cancer, gonorrhoea, pain and bronchitis. Objective: The study was designed to explore anti-nociceptive potential of aqueous extract of Nymphaea lotus leaf, its possible mechanism of action, and antioxidant properties. Methods: The anti-nociceptive activity of Nymphaea lotus (50, 100 and 250 mg/kg) was explored using writhing, formalin, tail clip and hot plate tests, while formalin test was used to investigate the involvement of opioid, dopamine, serotonin, K+ channel blocker, ?1-adrenergic and ?2- adrenergic systems. The antioxidant effect was carried out using DPPH, nitric oxide free radical scavenging activity and the reducing power effect. Total phenolic and flavonoids contents were also explored. Results: Oral administration of N. lotus in doses of 50, 100 and 250 mg/kg recorded a significant (p
