Objective:To study the analgesic and acute anti-inflammatory effect of the ethanolic extract of the leaves of Paederia foetida (EEPF) on experimental animal models. Materials and Methods: Fresh leaves were collected, air-dried, powdered, and percolated in 95% ethanol. Acute toxicity test was done according to OECD guidelines. Healthy albino rats (150-200 gm) of either sex were taken and divided into five groups with six animals in each group for central analgesic activity by tail flick method. Peripheral analgesic activity by 1% glacial acetic acid induced writhing test by taking albino mice (20-30 gm) of either sex which were divided into three groups with six animals in each. EEPF was used in a dose of 500 mg/kg bodyweight subcutaneously for tail-flick method and orally for writhing test. In tail-flick method the basal reaction time was taken and a cut-off period of 10 sec was observed. Reaction time were recorded at predrug, 15, 30, 60, 90, 120, 150 and 180 minutes after administration of drug . The standard drug used for central analgesic activity was pethidine 5 mg/kg bw, naloxone 1mg/kg as antagonist and naloxone 1mg/kg bw with 500mg/kg bw of EEPF to study the central mechanism of action. The standard drug used for peripheral analgesic activity was aspirin 100mg/kg bw orally. A control group was maintained in all the models. For anti-inflammatory study, three groups of animals of either sex (n = 6), weighing 150-200g of the species Rattus norvegicus were taken for the study. Group A was taken as control (Normal salie, 10 mL/kg body weight), Group B as test group (EEPF 500 mg/kg body weight), and Group C as standard (Aspirin 100 mg/kg body weight). The animals were studied for acute inflammation by Carrageenan-induced rat paw edema. Statistical analysis  was done by one-way analysis of variance followed by multiple comparison tests.Results: EEPF significantly increased the reaction time in tail-flick method (p<0.05) whereas the combination of naloxone and EEPF decreased the reaction time indicating that naloxone inhibits the analgesic effect of EEPF. In 1% glacial acetic acid induced writhing EEPF reduced writhing significantly In acute inflammation, there was significant inhibition of paw edema in Groups B, C in comparison with Group A (P < 0.05). Conclusion:The ethanolic extract of Paederia foetida has significant analgesic and anti-inflammatory activity.

Important Medicinal Plant

Background: Vitex negundo Linn (Family: Verbenaceae), locally known as ‘Nirgundi’ an important medicinal plant is a woody, aromatic shrub growing to a small tree. It commonly bears tri- or penta-foliate leaves on quadrangular branches, which give rise to bluish-purple coloured flowers in branched tomentose cymes. It has been claimed to possess analgesic activity apart from many medicinal properties. The aim of the present study was to evaluate both the peripheral and central analgesic activity of ethanolic extract of Vitex negundo flowers (EEVNF) in experimental animals.Methods: Acute toxicity test was done following the Organization of Economic Cooperation and Development guidelines. EEVNF (100mg/kg, 200mg/kg, and 400 mg/kg body weight [b.w.] p.o) was evaluated for peripheral analgesic activity by the acetic acid (0.7%) induced writhing test and central analgesic activity by the tail flick method respectively using aspirin (100mg/kg b.w. and 300mg/kg b.w.) as the standard drug.Results: EEVNF significantly decreased the number of writhing in writhing test at all the doses (p<0.001) and increased the reaction time in tail-flick method (p<0.001) at all the doses when compared to control. EEVNF in the dosage of 400mg/kg b.w. produced analgesic effects which was comparable with that of the standard drug aspirin at dose 100mg/kg b.w in writhing test and produced greater analgesic activity than that of standard drug aspirin at dose 300mg/kg b.w in tail flick method.Conclusions: EEVNF has significant peripheral and central analgesic activity.

AbstractThe objective of this work was to study the analgesic and anti-inflammatory activity ofHealthy albino rats (150–200 g) and mice (25–50 g) were arranged and divided into five groups. Group 1 received distilled water and served as control, groups 2, 3, 4 were treated with TG stem extract (100, 200, 400 mg/kg) and group 5 received standard drug. For analgesic activity, the radiant heat method and writhing test were used, and for anti-inflammatory activity, the paw oedema model and granuloma pouch method were used. Statistical analysis was done by one-way analysis of variance followed by the t-test.In the radiant heat method, there was a dose-dependent increase in reaction time in TG stem extract (100, 200, 400 mg/kg) and standard drug (buprenorphine). In the writhing test, TG stem extract (200, 400 mg/kg) and aspirin decreased the number of writhes which was significant (p<0.01, p<0.001) as compared to controls. The percentage protection was 8.88%, 15.55%, 22.22% and 35.55% in groups 2, 3, 4 and 5, respectively. In the rat paw oedema test, TG stem extract (200, 400 mg/kg) and aspirin showed 20%, 40% and 54% inhibition of oedema which was statistically significant (p<0.05, p<0.01, p<0.001), respectively, as compared to control at the end of 4 h. In the granuloma pouch method, TG stem extract (100, 200, 400 mg/kg) and aspirin showed 13.33%, 22.22%, 33.33% and 66.66% inhibition of granuloma, respectively, which was significant (p<0.05, p<0.01, p<0.001).TG stem extract possesses significant anti-inflammatory and analgesic activity.

The aim of this study was to phytochemically investigate the ethanolic extract of Hibiscus sabdariffa Linn. calyces and to evaluate the analgesic, anti-microbial and anti-diarrheal activities of this. The calyces of Hibiscus sabdariffa were separated from the other plant parts and sun dried and extracted using ethanol and phytochemically and pharmacologically evaluated.Different Phytochemical tests were performed for phytochemical screening and for determining the functional groups. Different methods like Disc diffusion method for antimicrobial activity determination, Castor oil induced diarrhea in mice method for the antidiarrheal study and Acetic acid induced writhing test for analgesic activity were employed. Phytochemical screening of the calyces of Hibiscus sabdariffa ensured the presence of alkaloid, flavonoids, saponins, tannins in the crude ethanolic extract. The peripheral analgesic activity was evaluated by acetic acid induced Writhing method. The extract produced 66.85% (p< 0.001) inhibition of writhing in mice at the dose of 500-mg/kg body weight, which is comparable to diclofenac sodium (78.45% (p<0.001) at the dose of 25mg/kg). The anti-diarrheal activity of the crude extract of Hibiscus sabdariffa was evaluated using the model of castor oil induced diarrhea in mice. The crude etanolic extract of Hibiscus sabdariffa (calyces) showed a marked antidiarrhoeal activity at dose of 500 mg/kg-body weight as compared to the standard antidiarrhoeal agent loperamide (dose:50mg/kg-body weight). Hibiscus sabdariffa caused an increase in latent period i.e. delayed the onset of diarrhoeal episode and decreased the frequency of defecation. Anti-microbial activity was tested using a number of micro-organisms. The peripheral analgesic activity of the ethanolic extract of the calyces of Hibiscus sabdariffa against acute inflammatory pain was significantly high as compared to potent inhibitory activity of Diclofenac (25mg/kg). Therefore, it is likely that the ethanolic extract at a dose of 400mg/kg might suppress the formation of these substances or antagonize the action of these substances and thus exerts its analgesic activity in acetic acid-induced writhing test. Anti-diarrheal activity was present in the ethanolic extract (500mg/kg) which indicate that the drug in decreased intestinal motility. This plant sample didn’t show any antimicrobial activity.

The anti-inflammatory and analgesic properties of the 85 % methanolic extract of Withania somnifera (WS) root was investigated and the anti-inflammatory effect was compared with the standard drug indomethacin. Analgesic activity was carried out by hot plate and tail flick method. Anti-inflammatory activity was carried out by carraggenan induced paw edema and Freund’s adjuvant induced arthritis. The results are related with evaluation of the analgesic activity in hot plate and tail flick method, they reveal that methanolic extract has exhibited significant activity (P<0.05) at 150 mg/kg b.wt, itself, whereas, the percentage inhibition exhibited by WS (350 mg/kg b.wt,) in carrageenan induced paw edema is found to be nearer to that of standard drug (10 mg/kg b.wt.). In Freund’s adjuvant induced arthritis, WS is seen to decrease the paw volume significantly (P<0.05). Significant (P<0.05) protection is also observed by elevating antioxidant enzymes. WS does not exhibit toxic effect which is observed in standard drug treatment. The 85 % crude methanolic extract does not present toxic effect as observed in indomethacin treatment. However, the extract has exhibited analgesic, anti-inflammatory and antioxidant activities.
