Anogeissus pendula Edgew has been reported to be used in gastric disorder even though no attempt has been made to evaluate the same. The present study was designed to evaluate the hydroalcoholic extracts of stem bark and leaves for in vivo acute antiulcer and anti-inflammatory activities. Antiulcer activity was studied by pylorus ligation induced ulcers while anti-inflammatory activities was studied by carrageenan induced paw edema. The extract of stem bark at 200 and 400 mg/kg b. w., significantly (P<0.05) reduced ulcer index whereas extracts of both stem bark and leaves significantly (P<0.001) reduced paw diameter at the fifth hour. The hydroalcholic extract of stem bark of A. pendula possesses more significant antiulcer and anti-inflammatory activity than the hydroalcholic extract of leaves may be due to the presence of higher amount of phenolic compounds.


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: Knema attenuata (Myristicaceae), popularly known as “wild nutmeg,” is an endemic tree species from Western Ghats, which has been used in folk medicine. Conventionally, the stem bark of K. attenuata is used for treating inflammatory conditions without any scientific information available for the same. The present study was undertaken to evaluate the anti-inflammatory activity of the ethanolic stem bark extract (ESBE) of K. attenuata using in vivo and in vitro screening models. Methods: The ethanolic extract of stem bark was prepared by soxhlation, and its cytotoxicity in RAW 264.7 cell line was assessed using MTT assay method. In vivo anti-inflammatory effect of extract was estimated in rats using carrageenan-induced paw edema model and cotton pellet-induced granuloma model. The in vitro anti-inflammatory activity of the extract was evaluated by cyclooxygenase and lipoxygenase inhibition assay, estimation of myeloperoxidase activity, and determination of cellular nitrite levels in lipopolysaccharide-stimulated RAW 264.7 macrophage cells. Results: Toxic symptoms were not observed for the ESBE. The extract demonstrated significant anti-inflammatory activity in both in vivo and in vitro models. The anti-inflammatory action exhibited by the extract was a result of the inhibition of leukocyte migration and nitric oxide pathway and partially by inhibition of mediators such as prostaglandins and leukotrienes. Conclusion: Findings from the study provide the evidence for the popular use of stem bark extract of K. attenuata as a potential anti-inflammatory agent.

Aims. Pterocarpus santalinoides is used in Beninese folk medicine for treatment of gastroenteritis. This study aims to compare the antimicrobial, antioxidant, and anti-inflammatory activity of the hydroalcoholic extracts of the leaves, trunk bark, and root. Materials and Methods. The antimicrobial activity was evaluated by the broth microdilution method on 06 bacterial strains including 03 wild-type strains (Escherichia. coli 0157H, Salmonella sp., and Staphylococcus aureus sp.) and 03 reference strains (E. coli ATCC 25922, S. aureus ATCC 29213, and Pseudomonas aeruginosa ATCC 27853), whereas the anti-inflammatory activity was performed by the carrageenan-induced paw edema method on rats. The DPPH-free radical scavenging was used to determine the antioxidant activity. Results. The MICs of the leaf extracts varied from 6.25 to 25 mg/mL for all strains. The MICs of the stem bark extracts were 6.5 to 25 μg/mL for five strains (E. coli 0157H, S. aureus ATCC 25922, Salmonella sp., E. coli ATCC 25922, and P. aeruginosa ATCC 27853) and 3.125 mg/mL for S. aureus. Concerning the root extracts, the MICs varied from 12.5 to 50 mg/mL. The best anti-inflammatory power was obtained with the stem bark extract with the percentages of inhibition of 36.09%, 38.98%, and 39.50%. The DPPH test showed that the hydroethanolic extract of the 03 parts of P. santalinoides has a moderate antiradical power compared to the control which was quercetin. Conclusion. In view of the different pharmacological activity recorded, the extract of the leaves should be recommended to treat patients suffering from gastroenteriditis.

Morinda lucida Benth (Rubiaceae) is a versatile plant used in traditional medicine for the treatment of a variety of ailments and the claims of its efficacy are particularly remarkable in the treatment of infections and immuno-inflammatory disorders. This study evaluates the anti-inflammatory properties of methanolic stem bark extract and fractions of M. lucida and also identifies the phytochemicals responsible for its anti-inflammatory activity. The crude extract was subjected to liquid- liquid partitioning successively with n- hexane, ethylacetate, butanol and water. High performance liquid chromatography (HPLC) of the four fractions and Vacuum Liquid Chromatography fraction (VLC) of the promising fraction was evaluated. The effect of the fractions on egg albumen induced rat paw oedema were also evaluated. Anti-inflammatory activity of the fractions was further screened using xylene induce ear oedema models and human red blood cell membrane stabilization test. Ulcerogenic test on the normal stomach mucosa was also evaluated. The result of the egg albumen induced rat paw oedema showed that the butanol fractions maximally inhibited egg albumen induced effect at 400 mg/kg (70%) and 200mg/kg (67.5%) after 180 minutes compared to the positive control, ibuprofen (20mg/kg) with 100% inhibition after 180 minutes. The result of the xylene induced ear oedema showed that the inhibition produced by 100 µg/ear of the Butanol fraction (BF) was 56.67 % and was greater than inhibition produced by 200 µg/ear of ibuprofen (38.89 %). HPLC analysis of the fractions revealed the following phytocompounds; Cytreo- a-pyrone, Cytosporin- J and Waol A. Ulcerogenic test was negative at the doses of 200 mg/kg and 400 mg/kg of the fractions when compare with the indomethacin (positive control) at dose of 50 mg/kg. Human red blood cell membrane stabilization assay showed that BF-VLC 2 (Dichloromethane: methanol (8:2) VLC of Butanol fraction) exhibited concentration dependent inhibition of heat-induced haemolysis while other extract showed a non- concentration dependent inhibition of haemolysis when compared to the standard, ibuprofen. These findings suggest that the stem bark of M. lucida possess promising anti-inflammatory phytocompounds which justify its use in ethno-medicine.
