Objective To study the hypnotic and anticonvulsant activities of the leaves of Eucommia ulmoides(LEU),the total alkaloids were extracted from LEU using water-acid method.Methods Mice were divided into five groups,including groups contained total alkaloids in three different doses,negative and positive control groups.Direct hypnotic experiment in mice,pentobarbital sodium synergistic experiment,and anticonvulsant experiment were used.The numbers of spontaneous activities,sleep rate,sleep latency,sleep time,convulsion rate,and convulsion latency of the mice were recorded and analyzed.Results The total alkaloids from LEU could increase the sleep rate,significantly lengthen the sleep time,and shorten the sleep latency of mice.Even the low dose of total alkaloids(0.33 g/kg)showed significantly different activities with negative control group(physiological saline)with the synergistic effect of the superthreshold dose of pentobarbital sodium.Furthermore,the total alkaloids efficiently inhibited the convulsion caused by nikethamide.Conclusion The total alkaloids from LEU have the excellent sedative,hypnotic,and anticonvulsant activities in mice,with high safety and little drug side effects.Therefore,they have the protential development prospects in sedative-hypnotic drugs.     

Pharmacological activities investigation of crude extracts and fractions from Qualea grandiflora Mart

This study investigates pharmacological activities of crude hydroalcoholic extract and fractions of Qualea grandiflora Mart. leaves employing different experimental models using mice. The treatment with crude hydroalcoholic extract (EH) in a dose of 500 mg/kg, i.p. caused: signs of central nervous system depressant action in the Hippocratic screening test, confirmed by the potentiation of sodium pentobarbital sleeping time. Increasing in the latency time of hot plate assay that indicate an analgesic effect; significantly delaying of the onset of clonic PTZ convulsions, increasing in the time for death, suppressing of the tonic PTZ convulsion, and decreasing of severity and number of convulsions. The median lethal dose of EH was 1.321 mg/kg. The convulsions induced by PTZ, ethyl ether fraction (300 mg/kg, i.p.) was more active in increasing the latency time for first convulsion, moreover, the hexane fraction, at the same dose, was more active in increasing the time for death and/or avoiding the death. Both did not cause disturbance in motor coordination at the dose of 500 mg/kg, assessed by rotarod test. These results suggest that the crude extract of leaves of Qualea grandiflora Mart. has a central nervous system depressant action, an analgesic effect and behave as a potential anticonvulsant.

Central nervous system depressant activity of an ethyl acetate extract from Ipomoea stans roots

Ipomoea stans Cav., popularly known as "tumbavaqueros", is a plant widely used in Mexico for the treatment of epileptic seizures and nervous disorders. This work researched the action of the ethyl acetate extract from the root of I. stans (IS-EAE) on the central nervous system (CNS). The administration of IS-EAE (2.5 and 5.0 mg/kg, i.p.) produced an anxiolytic effect in mice. This extract (20.0 and 40.0 mg/kg, i.p.) significantly reduced spontaneous motor activity. 2.5, 5.0, 10.0, and 20.0 mg/kg of IS-EAE protected mice against pentylenetetrazole-induced convulsions and increased the hypnotic effect induced by pentobarbital. The administration of IS-EAE was able to increase the release of GABA in brain cortex of mice. These results suggest that IS-EAE possess anxiolytic and anticonvulsant effects, and could have potential sedative effect, probably through a GABAergic system. The extract did not show antidepressant effects on mice exposed to forced swimming test.

Evaluation of sedative and anticonvulsant activities of Unmadnashak Ghrita

'Unmadnashak Ghrita' (UG) is a ayurvedic formulation containing Ferula narthex (6 g), Gardenia gummifera (6 g), Ellataria cardamom (6 g), Bacopa monneri (6 g), and cow's ghee (clarified butter fat) (76 g). In the present study, neuropharmacological activities of UG were evaluated for its gross behavioural effect, pentobarbitone sleeping time, spontaneous locomotor activity, antagonism to amphetamine induced hyperlocomotor activity, analgesic activity by tail flick test, rota-rod performance (motor coordination test), maximal electroshock (MES) induced seizures, and pentylenetetrazol (PTZ) induced convulsions in mice. The formulation showed CNS-depressant activity in gross behavioural test, potentiated pentobarbitone sleeping time and there was significant decrease in spontaneous locomotor count in mice. The formulation also antagonized the behavioral effects of CNS-stimulant drug amphetamine, and showed analgesic effect in mice. UG failed to affect the motor coordination test. The formulation also protected mice from MES and PTZ induced convulsions. These results suggest that UG has CNS-depressant and anticonvulsant activity in mice.
