Introduction: Annona senegalensis Pers (Annonaceae) and Piliostigma thonningii (Schum.) (Leguminoseae)  are two medicinal plants used, often in combination, in traditional Togolese medicine for the treatment of diseases with an inflammatory component. Objective: The aim of this study is to evaluate the anti-inflammatory effect of the hydro-ethanolic extract (EHEM) of the combination of A. senegalensis and P. thonningii (1: 1, m: m). Methods: The ovalbumin-induced allergic airway asthma model was used. Animals made asthmatic were treated with EHEM at doses of 250 and 500 mg / kg. Inflammation markers including histamine, nitric oxide (NO), vascular leakage, leukocyte infiltration in the airways, and malondialdehyde (MDA), were measured. Results: Compared to the SNT group, EHEM inhibits the infiltration of the airways by leukocytes (850,00 × 103 ± 50 cells / mL vs 1830 × 103 ± 53,85 cells / mL for ST500 mg / kg, P <0,05). It inhibited vascular permeability to Evans Blue (10,40 ± 0,270 μg / mL vs ST500, p<0,05). It inhibited histamine release (13,95 ± 0,937 μg / mL vs 32,78 ± 1,044 μg / mL, p<0,05) and NO production (0,211 ± 0,008 Μm vs 0,315 ± 0,022 μM, p<0,05). It finally inhibited MDA production (14,66 ± 0,533 nM / mL vs 9,014 ± 0,366 nM / mL and 7,149 ± 0,300 nM / mL, p<0,05) in lung tissue. Conclusion: Our results suggest that EHEM inhibits OVA-induced inflammation. These results justify the use of this combination of plants in traditional Togolese medicine. Keywords: Inflammation, malondialdehyde, Annona senegalensis, Piliostigma thonningii.

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.

Four new sesquiterpenoids (1–4) and six known sesquiterpenoids (5–10), were isolated from the EtOAc phase of the ethanolic extract of Ainsliaea yunnanensis. Their structures were established by spectroscopic methods, including 1-D, 2-D NMR and HPLC-MS. All compounds were tested for their anti-inflammatory effect by the inhibition of the activity of NLRP3 inflammasome by blocking the self-slicing of pro-caspase-1, which is induced by nigericin, then the secretion of mature IL-1β, mediated by caspase-1, was suppressed. Unfortunately none of the compounds showed an anti-inflammatory effect.

Background: Anti-inflammatory effect can be exerted by Carica papaya. Objective: The purpose of the present study was to see the anti-inflammatory effect of ethanolic extract of Carica papaya leaves and indomethacin in carrageenan induced rat paw edema animal model. Methodology: This was an animal study carried out in the Department of Pharmacology at Dhaka Medical College, Dhaka, Bangladesh during the period from July 2014 to June 2015 for a period of one (01) year. The leaves of Carica Papaya collected from Botanical garden, Mirpur, Dhaka, Bangladesh. The animals were divided into four groups. The animals were divided into four groups. In all the animals granuloma were induced by implantation of autoclaved cotton pellet on the 1st day and they treated as follows: Group I were served as control that was received normal saline. Group II were received ethanolic extract of Carica Papaya leaves. Group III were received ethanolic extract of Carica Papaya leaves. Group IV were received indomethacin. On the 15th day animals were anesthetized, implanted pellets were dissected out, dried at hit air oven and the final weights were measured. Result: The experiment was carried out on 48 Long Evan Norwegian rats. Rats were divided in 4 groups of six animals each. The mean increase of weight of cotton pellet was 48.06±1.02, 24.48±0.36, 22.42±0.56 and 18.02±0.43 in group I, II, III and IV respectively. The inhibition of granuloma formation was 49.06%, 53.35% and 62.51% in group II, III and IV respectively. Conclusion: In conclusion the ethanolic extract of Carica Papaya leaves has effects on cotton pellet induced granuloma formation in experimental rat.

Calendula officinalisis an annual herb from Mediterranean origin which is popularly used in wound healing and as an anti-inflammatory agent. In this study, the ethanolic extract, the dichloromethane, and hexanic fractions of the flowers from plants growing in Brazil were produced. The angiogenic activity of the extract and fractions was evaluated through the chorioallantoic membrane and cutaneous wounds in rat models. The healing activity of the extract was evaluated by the same cutaneous wounds model through macroscopic, morphometric, histopathologic, and immunohistochemical analysis. The antibacterial activity of the extract and fractions was also evaluated. This experimental study revealed thatC. officinalispresented anti-inflammatory and antibacterial activities as well as angiogenic and fibroplastic properties acting in a positive way on the inflammatory and proliferative phases of the healing process.
