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.

The Chir Pine,Pinus roxburghii, named after William Roxburgh, is a pine native to the Himalaya.Pinus roxburghiiSarg. (Pinaceae) is traditionally used for several medicinal purposes in India. As the oil of the plant is extensively used in number of herbal preparation for curing inflammatory disorders, the present study was undertaken to assess analgesic and anti-inflammatory activities of its bark extract. Dried and crushed leaves ofPinus roxburghiiSarg. were defatted with petroleum ether and then extracted with alcohol. The alcoholic extract at the doses of 100 mg/kg, 300 mg/kg, and 500 mg/kg body weight was subjected to evaluation of analgesic and anti-inflammatory activities in experimental animal models. Analgesic activity was evaluated by acetic acid-induced writhing and tail immersion tests in Swiss albino mice; acute and chronic anti-inflammatory activity was evaluated by carrageenan-induced paw oedema and cotton pellet granuloma in Wistar albino rats. Diclofenac sodium and indomethacin were employed as reference drugs for analgesic and anti-inflammatory studies, respectively. In the present study, the alcoholic bark extract ofPinus roxburghiiSarg. demonstrated significant analgesic and anti-inflammatory activities in the tested models.
