The present study investigates the anxiolytic activity of NR-ANX-C, a standardized polyherbal formulation containing the extracts ofWithania somnifera, Ocimum sanctum, Camellia sinensis, Triphala, and Shilajit in ethanol withdrawal- (EW-) induced anxiety behavior in rats. Ethanol dependence in rats was produced by substitution of drinking water with 7.5% v/v alcohol for 10 days. Then, ethanol withdrawal was induced by replacing alcohol with drinking water, 12 hours prior to experimentation. After confirming induction of withdrawal symptoms in the alcohol deprived animals, the anxiolytic activity of the test compound in graded doses (10, 20, and 40 mg/kg) was compared to the standard drug alprazolam (0.08 mg/kg) in the elevated plus maze and bright and dark arena paradigms. In our study, single and repeated dose administration of NR-ANX-C reduced EW-induced anxiety in a dose-dependent manner. Even though the anxiolytic activity was not significant at lower doses, NR-ANX-C at the highest dose tested (40 mg/kg) produced significant anxiolytic activity that was comparable to the standard drug alprazolam. Based on our findings we believe that NR-ANX-C has the potential to be used as an alternative to benzodiazepines in the treatment of EW-induced anxiety.

Objective: Anxiety is classified as a form of sub-acute or chronic fear. Root of Acorus calamus has been traditionally used as an anxiolytic. The aim of the study is to assess the anxiolytic activity of ethanolic extract of A. calamus (EEAC) by elevated plus-maze test on Albino mice. Methods: Albino mice of either sex were taken and divided into five groups, each consisting of 5 mice. One group was used as control, one as standard (diazepam), and three as test groups treated with 100, 200, and 400 mg/kg of EEAC. The drugs, that is, 10 ml/kg of normal saline for control, diazepam 2 mg/kg (standard), and 100, 200, and 400 mg/kg EEAC (test groups) were injected intraperitoneally (i.p.), 30 min before placing them in the center of the maze. The preferences of the animal to open/enclosed arm, average time spent in open arm, and numbers of entries in open arm were compared in each group. Data were statistically analyzed by one-way analysis of variance followed by multiple Dunnett’s test. Results: The number of entries in open arm and the average time spent in the open arm by the mice is increased by EEAC in a dose-dependent manner. Conclusion: EEAC has anxiolytic activity.

Abstract Background Brassica nigra is a plant of Brassicaceae family, which possesses numerous medicinal values. Our present study is intended to assess the potential in vitro thrombolytic, anthelminthic, cytotoxic and in vivo anxiolytic properties of MCE of B. nigra flowers. MCE was fractioned for separating the compound on the basis of polarity by using chloroform, n-hexane and ethyl acetate solvent. Thrombolytic and anthelminthic activities were explained by collecting human erythrocytes and earthworms as test models, respectively. Anxiolytic activity was evaluated by elevated plus maze and hole board models while cytotoxic test was conducted through brine shrimp lethality bioassay. Results MCE revealed the presence of alkaloids, flavonoids, tannin, diterpenes, glycosides, carbohydrates, phenols, fixed oils and fat. In case of thrombolytic test, the MCE, CSF, ASF and n-HSF had produced maximum clot lysis activity at 5 and 10 mg/ml dose conditions. Two different concentrations (10 and 20 mg/ml) of MCE and its fractions showed significant (p < 0.05) anthelminthic activities in a dose-dependent manner. Significant anxiolytic activity was observed for all fractions which was comparable to the standard drug diazepam (p < 0.05). Again, the cytotoxic screening also presented good potentials for all fractions. Conclusion From the findings of present study, we can conclude that MCE of B. nigra flowers and its fraction possess significant anxiolytic, anthelmintic, anticancer and thrombolytic properties which may be a good candidate for treating these diseases through the determination of bio-active lead compounds.

The current study was planned to evaluate comparative anti-inflammatory, analgesic and anti-pyretic activities of two newly synthesized organo-antimony (v) ferrocenyl benzoate derivatives with piroxicam. Anti-microbial activity of these compounds was also screened against two microorganisms. Analgesic effect of test compounds was evaluated by formalin-induced paw licking test in mice. The test compounds at 50 and 100 mg/kg b.w. doses exhibited significant (p<0.001) reduction of paw licking in treated mice comparable with standard drug piroxicam. Anti-inflammatory activity was assessed against carrageenan-induced paw oedema. The compound A produced anti-inflammatory effects comparable with standard piroxicam in dose dependent manner whereas compound B showed better effects than piroxicam at dose of 100 mg/kg body weight. To investigate anti-pyretic activity, fever was induced by administration of Brewer’s yeast in mice. Compound A showed highly significant inhibition of pyrexia (p<0.001) comparable to piroxicam after 3 hours while compound B (50 and 100 mg/kg) produced relatively lower anti-pyretic effect than standard drug. Antibacterial activity determined by disc diffusion method showed that compound B was relatively more effective than compound A against Staphylococcus aureus and Klebsiella pneumoniae. It is conceivable that both the tested compounds possessed anti-inflammatory, analgesic, anti-pyretic and anti-microbial effects even after the structural modification of parent compound.Bangladesh Pharmaceutical Journal 19(1): 15-24, 2016

The present study was carried out to investigate the possible analgesic, neuropharmacological and cytotoxic activities of the methanolic extract of Trigonella foenum-graecum Linn. leaves. The analgesic and neuropharmacological activities of Trigonella foenum-graecum Linn. were investigated at the doses of 100mg/kg, 200mg/kg and 400mg/kg of body weight in mice. Analgesic potential of the extract was evaluated for centrally acting analgesic property using tail immersion method and peripheral analgesic actions using acetic acid-induced writhing test. In acetic acid-induced writhing test, extract produced a significant (p < 0.001) inhibition of writhing response in a dose dependent manner but maximum inhibition (93.46%) of writhing was found at 400mg/kg dose. In tail immersion method, extract caused a significant (p < 0.001) increase in latency time and the results were comparable to the standard drug Diclofenac- Sodium. In addition, neuropharmacological property of crude extract was carried out by Hole cross and Open field test. The extract significantly (p < 0.05-0.001) displayed a dose dependent suppression of motor activity, exploratory behaviour. Furthermore, the extract was subjected to Brine Shrimp lethality bioassay for primary evaluation of cytotoxicity, where the extract was found to be highly toxic to Brine Shrimp nauplii, having LC50 values of 10μg/ml while the LC50 of the reference anticancer drug vincristine sulphate was 0.66μg/ml. The results of this present study suggest that the extract possesses analgesic, cytotoxic and CNS depressant activities.

Background: Cinnamon is one of the best known spices used as an herbal medicine. Cinnamaldehyde (CNM) the volatile oil, which was present in the essential oil of the bark, is the important constituents of cinnamon. Cinnamon has been investigated for its various effects like peptic ulcer protection, antioxidant property, inhibition of tau aggregation, anti-inflammatory activity, effect on cardiovascular system, anti-nociceptive activity, hepato-protective effects, hypolipidemic and antidiabetic activites. The present study was aimed to evaluate the anxiolytic effect of CNM per se and its interaction with diazepam in swiss albino mice.Methods: Anxiolytic activity was evaluated by elevated plus maze method. A group of 36 healthy mice of either sex weighing 20-30 grams were divided at random into six groups (n=6). CNM and diazepam were dissolved in tween twenty 20% to maintain uniformity of the solvent and given orally. Group I was given twenty 20% (10 ml/kg, p.o.), group II diazepam (0.5 mg/kg, p.o.), group III diazepam (1 mg/kg, p.o.), group IV cinnamaldehyde (100 mg/kg, p.o.), group V cinnamaldehyde (200 mg/kg, p.o.), group VI cinnamaldehyde and diazepam (100 mg/kg and 0.5 mg/kg, p.o.).Results: Cinnamaldehyde per se showed no anxiolytic effect at any dose (p<0.05). The standard drug diazepam has shown significant anxiolytic activity on elevated plus maze. Whereas combination of diazepam 0.5 mg/kg and cinnamaldehyde 100 mg/kg showed significant increase in the time spent in open arms as compared to all groups (p<0.05).Conclusions: CNM per se did not show any effect on anxiety but enhanced the action of diazepam when co-administered.

Background: Anxiety has become a very important area of research interest in psychopharmacology as it affects one-eighth of the population worldwide. Benzodiazepines are still the most commonly used drugs for anxiety despite a number of side effects.There is a need for newer antianxiety drugs with increased safety and efficacy, hence this study was undertaken to evaluate the anxiolytic activity of Nerium oleander flowers.Methods: Aqueous extract of Nerium oleander flowers (NA) was prepared using soxhalet apparatus. A total of 24 Albino rats aged 8-10 weeks of either sex weighing about 100-150g were obtained and divided into 4 groups of 6 rats each. Group I: Normal saline 10mL/kg. Group II: Diazepam 2mg/kg Group III: NA at a dose of 200 mg/kg Group IV: NA at a dose of 400mg/kg. The anxiolytic activity of Aqueous extract of NA was tested by elevated plus maze and digital actophotometer models. Data was analysed using one way ANOVA followed by Posthoc Tukey’s test.Results: In EPM model, the NA at 200, 400mg/kg doses showed that the number of entries and time spent in the open arms were increased significantly as compared to the control animals. (p<0.001). In Actophoptometer model, two different doses of NA (200 and 400mg/kg) showed a dose-dependent decrease in the locomotor activity, when compared to the control animals (p<0.001).Conclusions: Both the doses of aqueous extract of Nerium oleander flowers (200mg and 400mg/kg) possess anxiolytic activity and could be used as a new approach to treat anxiety.
