ETHNOPHARMACOLOGICAL RELEVANCE: Several Lamium species have been used to relieve pain in arthritic ailments in Turkish folk medicine.
AIM OF THE STUDY: To evaluate the anti-inflammatory and antinociceptive activities of different extracts prepared with methanol, dichloromethane, n-butanol and water from the aerial parts of some Lamium species of Turkish origin.
MATERIALS AND METHODS: Lamium eriocephalum subsp. eriocephalum, Lamium garganicum subsp. laevigatum, Lamium garganicum subsp. pulchrum and Lamium purpureum var. purpureum (Lamiaceae); for the anti-inflammatory activity, carrageenan-induced hind paw edema model, PGE(2)-induced hind paw edema model, and 12-O-tetradecanoyl-13-acetate (TPA)-induced mouse ear edema model and for the antinociceptive activity p-benzoquinone (PBQ)-induced writhing test in mice were employed.
RESULTS: The n-butanol extracts of Lamium garganicum subsp. laevigatum (LGL-BuOH), Lamium garganicum subsp. pulchrum (LGP-BuOH), and Lamium purpureum var. purpureum (LPP-BuOH) exhibited notable inhibition (16.5-28.9, 14.5-26.9, 12.3-21.5%, resp.) in carrageenan-induced hind paw edema model at doses of 200mg/kg without inducing any gastric damage. The LGL-BuOH (7.1-30.4%) and LGP-BuOH (5.9-24.1%) extracts also displayed potent anti-inflammatory activity against PGE(2)-induced hind paw edema model. LGL-BuOH and LGP-BuOH were also found to exhibit remarkable antinociceptive activity in p-benzoquinone-induced abdominal constriction test at a dose of 200 mg/kg (25.0 and 24.3%, respectively).
CONCLUSION: The experimental data demonstrated that Lamium garganicum subsp. laevigatum and Lamium garganicum subsp. pulchrum displayed remarkable anti-inflammatory and antinociceptive activities.
