Tinospora cordifolia Miers. is used in the Ayurvedic system of medicine for the treatment of jaundice, diabetes, and rheumatoid arthritis, and is also used as memory enhancer. But still there is no report of analgesic and neuropharmacological activities of the plant. For this reason, the present study was designed to evaluate analgesic and neuropharmacological activities of methanol extract of the aerial parts of Tinospora cordifolia. Analgesic activity of the crude extract at the dose of 200 and 400 mg/kg b.w. was evaluated for its central and peripheral pharmacological actions using hotplate and tail flick tests and acetic acid-induced writhing test respectively in mice. The extract produced a significant (p < 0.05-0.001) increase in pain threshold in hotplate and tail flick tests in a dose dependent manner. In acetic acid-induced writhing test the extract at both doses produced significant (p < 0.001) inhibition of writhing reaction but maximum inhibition (65.01%) of writhing was found at 400 mg/kg dose compared to the reference drug Diclofenac-Na at the dose of 10 mg/kg b.w. (77.07%). Neuropharmacological activity of the extract was also evaluated using rodent behabioural models; hole cross to evaluate motor activity, open field to evaluate exploratory behaviour and thiopental sodium-induced sleeping time to evaluate sedative potential of the extract. The extract significantly (p < 0.05-0.001) decreased motor activity and exploratory behavior of mice in hole cross and open field test respectively. The extract also produced rapid onset and maximized the duration of sleeping time when administered with thiopental sodium. Results of this study suggest that the aerial part of T. cordifolia possesses significant analgesic and CNS depressant activity.  Key words: Tinospora cordifolia; Menispermaceae; Analgesic; Neuropharmacological.DOI: 10.3329/sjps.v2i2.5822Stamford Journal of Pharmaceutical Sciences Vol.2(2) 2009: 31-37

Analgesic and central nervous system depressant activity of the methanol extract of Achyranthes aspera Linn. was assessed by using acetic acid induced writhing test, thiopental sodium induced sleeping time determination, hole cross test and open field test in albino mice. The extract (250 and 500mg/kg) showed a dose dependent inhibition of writhing response generation by acetic acid compared to reference drug diclofenac sodium (50mg/kg). Methanol (70%) extract of Achyranthes aspera (500 mg/kg) also produced rapid onset and maximized the duration of sleeping time when administered with thiopental sodium. The extract also decreased the motor activity and exploratory behavior of mice in hole cross and open field test. The overall experimental results suggest the analgesic and central nervous system depressant activity of the methanolic extract of Achyranthes aspera and justify its use in folkloric remedies. Key Words: Achyranthes aspera, Analgesic activity, Central nervous system depressant activity. doi:10.3329/sjps.v1i1.1807 S. J. Pharm. Sci. 1(1&2): 44-50

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.

Albizia lebbeck (Linn.) Benth. is a deciduous tree which is planted as ornamental and avenue tree almost all over Bangladesh. Leaves of the plant are used in ethnomedicine for the treatment of convulsion and CNS related disorder. This study was aimed to evaluate the neuropharmacological effects of the methanol extract of A. lebbeck leaves in Swiss albino mice. The locomotor effect of crude methanol extract of the plant was investigated by open field and hole cross tests while the anxiolytic activity was determined using elevated plus-maze (EPM) and light/dark box (LDB) tests. Furthermore, the sedative activity of the plant extract was assessed by sodium thiopental-induced sleeping time test. The results demonstrated that the methanol extract significantly (p < 0.001) reduced locomotion of the animals in both hole cross and open field tests in dose-dependent manner at 200-400 mg/kg b.w. In both EPM and LDB tests, the plant extract produced significant anxiolytic effect (p < 0.05) at the doses of 100-400 mg/kg b.w. In addition, it showed significant (p < 0.001) dose-dependent decrease in the onset of sleep and an increase in duration of sleep in sodium thiopental-induced sleeping time test. Preliminary phytochemical analyses of the plant extract revealed the presence of alkaloid, flavonoid, glycoside, saponin, tannin and resin. In acute toxicity test, the leaf extract did not exhibit any adverse effect in mice during 7 days treatment. The results of the present studies suggest that the crude methanol extract of A. lebbeck leaves possesses significant CNS depressant, anxiolytic and sedative properties and rationalize the traditional uses of the plant.Bangladesh Pharmaceutical Journal 21(2): 80-86, 2018

Marine natural products from seaweeds have been the focus of research for novel products of pharmacological interest. Bioactivities of the phytochemicals derived from marine algae are important ingredients in many products, such as cosmetics and drugs for treating cancer and other lifestyle disorders. In this context, the aim of the present study is to compare the anti-inflammatory, analgesic, antipyretic properties of the purified terpenoids from the selected red algae Hypnea musciformis, Gracilaria dura and Kappaphycus alvarezii. Initially, the acute toxicity of the purified terpenoid extract was analyzed and was greater than 4000 mg/kg bw. In vitro BSA denaturation assay revealed significant % inhibition as compared to control. In the carrageenan induced paw edema, the purified terpenoids extract of H. musciformis exhibited remarkable soothing activity with 68.8% percentage of inhibition, which was comparable with that of indomethacin. Meanwhile G. dura and K. alvarezii showed 53 and 50% of inhibition respectively. Analgesic activity was determined by hot plate and acetic acid induced writhing test. In the hot plate test, terpenoids extract of H. musciformis and G. dura significantly increased the hot-plate latency as compared to normal saline, which reflects their analgesic efficacy. In the writhing test, terpenoid extracts from H. musciformis, G. dura and K. alvarezii inhibited the writhing response induced by acetic acid in a concentration dependent manner that suggests its varied mode of inhibition of stretching episodes. Lastly, the antipyretic activity was analyzed. Terpenoid extracts from H. musciformis, G. dura and K. alvarezii revealed a significant (P < 0.01) antipyretic activity up to 180 min.  In summary, the study demonstrates the anti-inflammatory, analgesic and antipyretic effects of terpenoids extracts from H. musciformis, G. dura and K. alvarezii on experimental models, suggesting its therapeutic potential in the treatment of peripheral painful and inflammatory pathologies.

In Bangladesh, numerous tribal people of Chittagong Hill Tracts have been using different parts of Thysanolaena maxima Roxb. for many years. The present study was designed to investigate CNS depressant and analgesic activities of methanol extract of the aerial parts of the plant in mice models. CNS depressant activity of the crude extract (200 and 400 mg/kg) was evaluated using open field, hole cross and thiopental-induced sleeping time tests using diazepam as the standard. Analgesic activity was determined using acetic acid-induced writhing and hot plate tests using diclofenac sodium as the standard. The extract showed dose dependent suppression of locomotion in open field and hole cross tests and exerted sedative action in thiopental induced sleeping time. In the open field and the hole-cross tests, maximum CNS depressant activity was observed at 90 min after administration of extract and the standard drug. The extract significantly induced the onset of sleep and prolonged the sleeping time in thiopental induced sleeping test compared to the control group. The extract produced significant (p < 0.05) analgesic activity by inhibiting writhing by 41.89% and 60.81%, at doses of 200 and 400 mg/kg body weight, respectively, which was comparable to the inhibition of diclofenac sodium (73.64%). Additionally, in hot plate test, the extract exhibited a significant (p < 0.05) increase in pain threshold in a dose dependent manner. The findings of the study are encouraging and demands further investigation of other bioactivities with isolation of pure compounds. Dhaka Univ. J. Pharm. Sci. 20(2): 227-233, 2021 (December)

Background: Pain and pyrexia are the warning signals, primarily protective in nature, that cause discomfort and suffering and may even be unbearable and incapacitating. The modern drugs (like opioids, NSAIDs, corticosteroids) currently used for the management of pain, fever and inflammatory conditions, present with many known adverse effects. Tinospora cordifolia known as Giloe, widely used in folk medicine due to its property to cure a number of diseases. Hence the present study was undertaken to explore the analgesic activity of water-soluble extract of stem of T. cordifolia in albino rats in experimentally induced pain.Methods: Present study was done in the department of pharmacology, albino rats were used to study the analgesic activity of T. cordifolia aqueous extract at the dose of 1.25g/kg,2.5g/kg and 5g/kg p.o. Various methods like Eddy’s hot plate, tail flick test and acetic acid induced writhing were used for the anti- nociceptive study.Results: In Eddy’s hot plate and tail flick test an increase in reaction time was observed with peak effect at 90min. Results were similar to the standard drug Tramadol in acetic acid induced writhing increase in time of onset, decrease in number and duration of writhing was observed.Conclusions: Aqueous extract of T. cordifolia was effective in all the three models of pain suggesting its possible action by central and peripheral mechanisms. Activity of T. cordifolia can be attributed to various phytoconstituents viz. protoberberine alkaloids, terpenoids, glycosides and polysaccharides. It can be developed as potent analgesic agent in future.
