Objective: The present study sought to evaluate the anti-inflammatory and analgesic activities of ethanolic extract from Tradescantia fluminensis leaves. Methods: The crude leaf extract of T. fluminensis was investigated for anti-inflammatory and analgesic activities in Wistar Albino rats and mice respectively. The anti-inflammatory activity was investigated using egg albumin induced oedema model while acetic acid and formalin-induced paw licking models were used to evaluate the analgesic activity. Results: The extract showed a significant (P<0.05) dose-dependent inhibition of inflammation and pain compared to the control group. Conclusion: The leaf extract possesses anti-inflammatory and analgesic activities. The activities could be attributed to phytochemicals present in the plant.


Medicinal plants are play significant impact in the personal medicine for most of the people all over the world as an alternative live saving medicines and most of their medicinal properties are well known for anticancer activity. The different extracts of Holoptelea integrifolia (H.integrifolia) leaves, stem bark and fruits were studied as a potent natural source of antimicrobial, antioxidant and wound healing potential. This work was carried out to evaluate antimicrobial, antioxidant and anti-inflammatory activity of different extracts of H.integrifolia. The antimicrobial activity of the H.integrifolia ethanolic extract was studied against five fungal and bacterial strains by utilizing the agar well diffusion method and MIC. Among several strain, the ethanolic extract of fruit has shown higher antimicrobial inhibition zone as 9.25-16 mm compare to other two extracts of stem and leaves as 10- 13.25 mm and 6-10.2 mm respectively. The antioxidant activities for different extract were also determined by DPPH free radical assay, Hydroxyl Radical Scavenging and Nitric Oxide Radical Scavenging Activity method. The anti-inflammatory activity also estimated basedon formalin induced paw edema method on Wistar albino rats. The different extracts of leaves, stem bark and fruit parts of Holoptelea integrifolia were estimated for in vivo anti-inflammatory activity against the animal model of female Wistar albino rats. The results of anti-inflammatory activity revealed that the Ethanol extracts showed vital and dose-dependent anti-inflammatory effects. Our findings revealed that aerial parts of H.integrifolia contais potential antimicrobial, antioxidant and anti-inflammatory compounds, which expose the medicinal potential of the selected plant could be a significant drug candidates against microbial, oxidative and inflammation-related pathological processes as a future alternative medicine.

  Objective: This study aims to perform phytochemical screening and investigate anti-inflammatory activity of extract from aerial part of the plant Plantago major L.Methods: Preliminary phytochemical screening of plant extract was carried out using standard qualitative procedures and anti-inflammatory activity was evaluated using carrageenan-induced paw edema model in male Wistar albino rats using plethysmometer. Diclofenac sodium (10 mg/kg, b.w.) was used as standard drug.Results: Preliminary phytochemical screening of the different extracts revealed that they were rich in secondary metabolite compounds such as carbohydrates, tannins, steroids, flavonoids, terpenoids, glycosides, fats and oils, alkaloids, phenolic compounds, and iridoid glycosides. The anti-inflammatory activity was evaluated using carrageenan-induced paw edema models in Wistar albino rats. The anti-inflammatory activity of methanolic extract (ME) was found to be dose dependent in carrageenan-induced paw edema model. The ME has shown significant (p<0.05) inhibition of paw edema, 61.11% and 55.55% on 4th hr at the doses of 900 and 600 mg/kg, respectively.Conclusion: The results of the present study demonstrate that ME of the aerial parts of the plant possess significant (p<0.05) anti-inflammatory potential.

Aim: This research was designed to evaluate the anti-inflammatory and analgesic activities of Parinari curatellifolia methanol leaf extract in albino rats. Methodology: Phytochemical screening was carried out using standard methods. Anti-inflammatory activity of the extract was done using egg albumin and formalin induced hind paw edema model. Analgesic effect was evaluated using hot plate induced pain and acetic acid induced writhing test. For each model twenty (20) rats were used, divided into five (5) groups of four (4) rats each. Results: Parinari curatellifolia revealed the presence of alkaloids, flavonoids, tannins and phenols while steroids, anthraquinone, terpenoids and glycoside were not detected. For the egg albumin induced inflammation, the group treated with the standard drug (indomethacin) and the group that received the highest dose of the extract were significantly lower (P<0.05) than all the other groups with percentage inhibitions at 25.56% and 24.44% respectively there was no significant difference (P>0.05). For the formalin induced anti-inflammatory activity, at the 1st hour, the normal control group had its paw volume significantly different (P<0.05) from the treated groups. This trend was observed at the 2nd, 3rd and 4th hour. The hot plate method results revealed significant increased (P<0.05) in the analgesic activity of PCMLE at 400mg/kg body weight and the drug treated group when the control was compared with the treated groups with percentage inhibition of 34.32% and 52.94% respectively. The acetic acid induced writhing test revealed that the extract at the three doses of 100, 200 and 400 mg/kg body weight, showed a significant (P<0.05) percentage inhibition of 32.31%, 36.92% and 47.69%, respectively compared to negative control. Conclusion: This justifies the use of Parinari curatellifolia locally in the management of pain and inflammation.
