Mentha arvensis Linn, a plant used as traditional medicine and in perfumery, has now been explored for its pharmacological activities as an anti-inflammatory and also as sedativehypnotic plant drug. The methanolic extract of the leaves after being processed, was taken for the pharmacological study. Anti-inflammatory activity was carried out on albino rats. Further, the activity was compared to ...

Spider monkeys (Ateles geoffroyi) use sites composed of one or more trees for sleeping (sleeping sites and sleeping trees, respectively). Beneath these sites/trees they deposit copious amounts of dung in latrines. This behavior results in a clumped deposition pattern of seeds and nutrients that directly impacts the regeneration of tropical forests. Therefore, information on the density and spat...

We evaluated the neuropharmacological profile of acetylated alphaand beta-amyrin (AcAMY) obtained by the acetylation of the isomeric mixture of alphaand beta-amyrin isolated from Protium heptaphyllum. Male Swiss mice were administered with AcAMY (2.5, 5, 10 and 25 mg/kg, i.p.), and anticonvulsant (pentylenetrazoleand pilocarpine-induced convulsions), sedative (barbiturate-induced sleep and open...

Ailanthus excelsa (Stem bark) are used in folk medicine for a treatment of inflammation, arthritis, expectorant, stimulant and asthma. Acute toxicity study of A. excelsa stem bark was performed on mice (Swiss) and albino rats (Wistar strain),given single doses 1,10, 50, 100 ,1000 and 2000mg/kg,po. showed normal behavior and no mortality up to 14 days except 500,1000 and 2000mg/kg dose 20%, 60.0...

The methanolic extract of Lycopus europaeus was evaluated on central nervous system. The methanolic extract produced significant sedative effect at the doses of 200, 400 and 600 mg/kg (by oral route), compared to reference substance diazepam in hole board and thiopental -induced sleeping time methods. While the hypnotic effect was calculated at the doses of 800 and 1000 mg/kg via oral pathway s...
