Materials and Methods Flower materialFresh plants of L. were collected from Haldwani, Nainital, India, in the month of November 2009 and recognized from Forest Study Institute, Dehradun by Dr. Veena Chandra. Preparation of the flower draw out The dried and coarsely powdered plants (20 g) of were extracted three times by maceration with hydromethanolic solvent (methanol: water; 4:1) for 7 days at space temperature. The combined draw out was filtered and the solvent was evaporated under reduced pressure (40 50C). Initial phytochemical screeningA initial phytochemical analysis was carried out to assess the presence or absence of numerous groups of phytochemicals. AnimalsMale albino mice (205 g) bred in Animal House facility of Division of Pharmaceutical Sciences, Bhimtal campus, Kumaun University or college, Nainital, India, were housed in cages with food and water and managed on a natural 12 h of light and dark cycle. All the experimental protocols were authorized by the Institutional Animal Honest Committee (# 4/2010) CPCSEA sign up quantity of the IAEC is definitely 490/01/a/CPCSEA. Drugs and treatmentImipramine, fluoxetine, and pentazocine (Ranbaxy Co., India); p-chlorophenylalanine (PCPA), L-arginine, L-NAME, and methylene blue (HiMedia); sildenafil and progesterone (Sigma, USA). Imipramine, fluoxetine, L-NAME, L-arginine, methylene blue, and sildenafil were dissolved in distilled water whereas TE, pentazocine, p-chlorophenylalanine, and progesterone were dissolved in 2% w/v Tween 80. The doses of the medicines used were selected based on earlier studies.[13,14,15] Different doses of TE (12.5, 25, 50 mg/kg) and imipramine (10, 20, 30 mg/kg) were administered intraperitoneally (i.p.) in a fixed volume of 1 mL/100 g body weight. All the treatments were given to different groups of animals each comprising six mice, 30 min before the pressured swim test (FST) or the locomotor test. The time-course effect of TE in FST was assessed in an self-employed group of mice, 15, 30, 60, or 120 min after administration of 25 mg/kg, i.p., of draw out. To study the involvement of mechanisms by which TE causes antidepressant-like action in FST, animals were treated with different medicines. Mice were pretreated with the sub-effective dose of imipramine (10 mg/kg, i.p.) and fluoxetine (5 mg/kg, i.p., a selective serotonin reuptake inhibitor) and 5 min later on they received vehicle or draw out (25 mg/kg) and 30 min later on animals were subjected to pressured swim test. In another set of experiments, PCPA (100 mg/kg, i.p., an inhibitor of serotonin synthesis) was given continually for four days. On the fourth day time, TE (25 mg/kg, i.p.) was given after 30 min of PCPA and 30 min later on mice were subjected to FST. In a separate series of experiments, the possible participation of sigma receptor in the antidepressant-like effect of TE was investigated. Sigma receptor agonist pentazocine (2.5 mg/kg i.p.) and antagonist progesterone (10 mg/kg s.c.) were injected to mice 5 min before administrating TE (25 mg/kg i.p.) and after 30 min, animals were subjected to FST. For studying the possible participation of L-arginine nitric oxide-cyclic guanosine monophosphate pathway in the antidepressant-like effect of TE, mice were pretreated with L-arginine, a precursor of nitric oxide (750 mg/kg, i.p., a dose that produces no effect in the pressured swim test) and vehicle. Thirty minutes after L-arginine, TE (25 mg/kg, i.p., a dose active in pressured swim test and no effect on the locomotor activity) and vehicle was injected and 30 min later on animals were subjected to FST. In another set of experiments, the effect of TE (25 mg/kg i.p.) with L-NAME (10 mg/kg, i.p., nitric oxide synthase inhibitor) and methylene blue (10 mg/kg i.p., an inhibitor of nitric oxide synthase.The antidepressant aftereffect of in the forced swim test was avoided by pretreatment with sildenafil and PSC-833 (Valspodar) L-arginine, whereas pretreatment of mice with nitric oxide synthase inhibitors potentiated the action. of cav. a types of continues to be reported.[12] Therefore, the purpose of this research was to research the antidepressant action of another species of also to elucidate its mechanism of action.
