Background: The antipyretic, analgesic and anti-inflammatory activities of two concentrations (100 and 200 mg/kg) of ethanolic extract of leaf, bark, flower and fruit pulp of C. fistula were determined in male wistar albino rats. Methods: Antipyretic activity was assessed by E. coli endotoxin induced pyrexia. Analgesic activity was assessed by hot plate, tail immersion and acetic acid induced writhing test. Anti-inflammatory activity was evaluated by carrageenan-induced rat paw edema assay. Result: Significant (p less than 0.05) antipyretic activity was exhibited from 2h onwards by bark extract @ 200 mg/kg and from 3h onwards by bark extract @100 mg/kg and leaves extract @ 200mg/kg as compared to control group. Significant (p less than 0.05) analgesic activity was shown by extract of bark @ 200 mg/kg as it is evident by increase in reflex time in hot plate (90,120,180 min), tail immersion test (120,180 min) and inhibition of writhing (32.12%). Significant (p less than 0.05) anti-inflammatory activity was exhibited from 3h post administration by bark @ 200 and leaves @ 100 and 200 mg/kg.

Objective: Because of adverse side effects, caused by NSAIDs, tolerance, and dependence induced by opiates, the use of these analgesic agents has not been successful in all cases. Therefore, alternative analgesic drugs from plant sources are the new target now days. The objective of this study was to evaluate the analgesic activity of ethanolic extracts of stem barks and leaves of Ficus religiosa. Methods: The analgesic activity of ethanolic extract of stem barks and leaves was evaluated in the Swiss albino mice model using acetic acid-induced writing response and Eddy’s hot plate method. Analgesic activity was demonstrated with the percentage inhibition of acetic acid induced writings and the percentage increased in latency time of paw licking. The potency of test extracts was compared with standard drug, Diclofenac. Results: Ethanolic extract of leaves and bark of F. religiosa showed potential analgesic activity from both methods. From Eddy’s hot plate model, it was observed that the percentage of increased latency time at 90 min by ethanolic extract of leaves and stem bark was found to be 70.81 % (8.54 min) and 70.78 % (8.53 min) respectively at a dose of 400 mg/kg. Both of these results are statistically significant (p<0.05) as compared to the test group. Furthermore, both of these extracts showed the dose-dependent and time-dependent increased in latency time and these results are compared to that of standard drug Diclofenac. Similarly, ethanolic extract of leaves and stem at 400 mg/kg significantly inhibited the number of writhings induced by acetic acid. The percentage inhibition of writhings by ethanolic extract of leaves at a dose of 400 mg/kg was 68.47 % which was similar to that of standard drug Diclofenac (68.47 %). However, ethanolic extract of bark showed relatively lower percentage inhibition (60.79 %) as compared to leaf extract and standard, but the result was significant as compared to that of the test group (p<0.05). Conclusion: Ethanolic extracts of F. religiosa stem bark and leaf possess both central and peripheral analgesic properties and these effects may be beneficial for the management of pain.

Papaver libanoticumis an endemic plant to Lebanese region (family Papaveraceae) that has not been investigated before. The present study aimed to explore the analgesic activity of dried ethanolic extract ofPapaver libanoticum(PLE) using tail flick, hot plate, and acetic acid induced writhing models in mice. The involvement of opioid receptors in the analgesic mechanism was investigated using naloxone antagonism. Results demonstrated that PLE exhibited a potent dose dependent analgesic activity in all tested models for analgesia. The analgesic effect involved activation of opioid receptors in the central nervous system, where both spinal and supraspinal components might be involved. The time course for analgesia revealed maximum activity after three hours in both tail flick and hot plate methods, which was prolonged to 24 hours. Metabolites of PLE could be responsible for activation of opioid receptors. The EC50 of PLE was 79 and 50 mg/kg in tail flick and hot plate tests, respectively. The total coverage of analgesia by PLE was double that of morphine in both tests. In conclusion, PLE proved to have opioid agonistic activity with a novel feature of slow and prolonged effect. The present study could add a potential tool in the armaments of opioid drugs as a natural potent analgesic and for treatment of opioid withdrawal syndrome.

Analgesic Activities

Background: NSAIDs like Aspirin etc. are randomly used for mild to severe types of pain but long-term and injudicious use of NSAIDs lead to a number of side effects. The present study is designed for exploring the analgesic potential of Curcuma longa Linn (Turmeric) in albino rats, which may widen the therapeutic horizon for the said agent.Methods: Ethanolic extract of Curcuma longa in the doses 100, 200 and 400mg/kg is given orally to 6 Wister rats against a control of normal saline and a standard using Aspirin (300mg/kg) and the animals were subjected to Eddy’s hot plate test at different time intervals i.e., 30, 60, 90 and 120 minutes after administration of the drugs and the parameters were noted.Results: The analgesic activity of Curcuma longa showed significant (p<0.05) increase in mean basal reaction time in Hot plate method when compared to the control (Normal saline). As the dose of the ethanolic extract of Curcuma longa was gradually increased from 100, 200 and 400mg/kg respectively, the analgesic activity significantly increased (<0.05). Effect of curcuma longa at a dose of 400mg/kg is found to be comparable with Aspirin.Conclusions: The results of this study suggest that turmeric (Curcuma longa) has significant analgesic activities in rats.

Temu giring (Curcuma heyneana Val & Zijp) is a traditional medicinal plant that is believed in community as an analgesic. The objective of this research was to determine the analgesic activity of the C. heyneana rhizome by using infra red (IR) thermal induction method in mice. Mice were divided into 7 groups. Group 1 served as negative control, group 2,3,4,5 served as treatment groups which is  given ethanolic extract of C. heyneana rhizome at  dose of 5, 25, 125, and 625 mg/kg respectively, group 6 and 7 served as  comparable groups, given antalgin 65 mg/kg and morphine sulphate 1.3 mg/kg respectively. The observation have been done, included to pain resistance of mice which exposed by infra red (IR) every 10 minutes for 80 minutes. The data were analyzed by ANOVA at the significance level of 95%. Ethanolic extract of C. heyneana at the doses of 25, 125, and 625 mg/kg had significant effect to reduce the pain compared to the negative control (p<0.05). Ethanolic extract of C. heyneana rhizome at dose of 125 mg/kg, had the same effect to antalgin 65 mg/kg  (p≥0.05), while the ethanolic extract of C. heyneana at the dose of 625 mg/kg had the same effect as morphine sulfate 1.3 mg/kg (p≥0.05). It can be concluded that ethanolic extract of C. heyneana rhizome has analgesic activity.   Keywords: temu giring, analgesic, Curcuma heyneana, rhizome

AbstractBackgroundThe current study evaluates the analgesic effect of different extracts ofHopea odorataleaves in mice followed by molecular docking and absorption, distribution, metabolism, excretion, and toxicity (ADME/T) analysis of isolated compounds derived from the plant with the COX-1 enzyme.MethodsIn the present study, the dried leaves ofH. odoratawere subjected to extraction using methanol, ethanol, and water.In vivoanalgesic activity was evaluated by using the acetic acid-induced writhing test and formalin-induced paw licking test, andin silicomolecular docking and ADME/T study were performed using Schrödinger Maestro (version 11.1) and online-based tools, respectively, on eight isolated compounds.ResultsThe results showed that the methanolic extract of leaves has highest significant dose-dependent analgesic activity at both 200 and 400 mg/kg followed by ethanolic extract of leaves. Among all the compounds, ampelopsin showed the best docking score of −7.055, ensuring strong binding affinity between the ligand and the receptor, and ADME/T analysis using Web-based tools ensures the compound has not violated Lipinski’s rule of five indicating its safety consumption.ConclusionsThe result confirms the analgesic activity ofH. odorataleaves in bothin vivoandin silicoassays. The data support ampelopsin to be a potent analgesic compound worthy of future clinical trials and its “drug-likeliness”
