Piliostigma Reticulatum

Use of plants as remedies dates back to the time of the oldest civilizations. Among these active ingredients, polyphenols play an important role. Piliostigma reticulatum, a plant whose barks are rich in condensed tannin is often used as an anti-inflammatory. The purpose of this work was to correlate the anti-inflammatory activity of extracts with their chemical composition through chromatography fractionation analyses (HPLC-DAD and HPLC-MS). The barks were extracted by moderate hydroethanol decoction followed by silica gel splitting with successively ethyl acetate, methanol and water. Anti-inflammatory activity was evaluated by the method of carrageenan induced hind paw edema in Wistar rats.  The chemical study was carried out by HPLC-DAD and HPLC-MS after isolation of the compounds by fractionation on Sephadex LH-20 gel. The bark hydroethanolic extract had shown ability to inhibit significantly the inflammation induced by carraghenan. Among the hydroethanolic bark extract fractions that methanol fraction had the best activity at 10 mg/kg with inhibition percentages similar to those of acetylsalicylic acid with 48.51% ± 2.26; 54.71% ± 5.13; 64.19% ± 6.70 vs. 54.69% ± 7.23; 57.83% ± 9; 65.13% ± 8.44 respectively. The HPLC-DAD analysis showed that the SF5 sub-fraction presented the best chromatogram with several peaks, three of which were high intensity. The latter would correspond to monomer, dimer and trimer of catechin according to the weights [M-H] + m / z: 291.07; 579.18; 867.27 obtained by HPLC-MS. The compounds responsible for anti-inflammatory activity would be condensed tannins. The latter would consist mainly of catechin oligomers.  Keys words: Piliostigma reticulatum, bark, anti-inflammatory activity, HPLC-DAD, HPLC-MS

Enhydra fluctuations an edible semi-aquatic vegetable plant are widely used in the traditional system of medicine. Ethanolic extract of Enhydra fluctuans was screened for analgesic & anti-inflammatory activity. Analgesic activity was evaluated by the hot plate method and anti-inflammatory activity was evaluated by formalin induce paw edema in Wistar rats (male). Ethanolic extract dose of 300 mg/kg reduce formalin induce paw inflammation and also increased the pain threshold in rats evidenced by hot plate method. The experimental results concluded that Enhydra fluctuans have significant analgesic and anti-inflammatory activity may due to flavonoid and phenolic compound content.

Objective: The object of the present study, the methanolic leaf extract of Zanthoxylum ovalifolium was examined for anti-inflammatory activity and tested using carrageenan-induced paw edema in albino Wistar rats. Materials and Methods: The rats were grouped into five, each group consisting of six animals, Group I (negative control) received 1 ml of saline, Group II (standard) received 10 mg/kg p. o. of indomethacin, and remaining three groups received three different doses (100, 200, and 400 mg/kg p. o.) of the methanolic leaf extract after 1 h 0.1 ml of 1% carrageenan injection. The result of anti-inflammatory activity was set up to be dose-dependent in the carrageenan-induced paw edema model. Results: The methanolic leaf extract has shown significant (p<0.001) inhibition of paw edema, 66%, 66.03%, and 69.29% on the 3rd h at the doses of 100, 200, and 400 mg/kg, p. o., respectively. The results were expressed as the Mean±standard error of mean and statistical significance was analyzed by ANOVA followed by Dunnett’s test. The methanolic leaf of Z. ovalifolium extract showed significant anti-inflammatory activity compared with the standard drug indomethacin. Conclusion: Methanolic leaf extract of Z.ovalifolium showed excellent results in the anti-inflammatory experiment so, the plant can be explored as a potential medicine in suppressing inflammation.

Background: Inflammation is a complex reaction to various injurious agents such as infections, trauma, foreign bodies, tissue necrosis, physical and chemical agents, that consists of vascular responses, migration and activation of leukocytes and systemic reactions. Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) are currently the most commonly prescribed drugs for treating pain and inflammation. The traditional NSAIDs usually cause various adverse effects on long term use. Gmelina arborea Linn (Gambhari) belongs to family Verbenaceae. The roots, leaves, flowers, fruits and bark are used for treating different ailments as anthelmintic, analgesic, anti-pyretic, antidiabetic, antimicrobial, diuretic and other common disorders.Methods: The study was carried out by using inflammatory models in wistar rats. The anti-inflammatory activity of G. arborea was compared with standard drug aspirin. The study parameters for acute inflammation was assessment of reduction in inflammation & the percentage inhibition of the paw edema. The parameter for the sub-acute inflammation was percentage inhibition of the dry granuloma weight.Results: The low and high dose of G. arborea root extract significantly showed the anti-inflammatory activity when compared to control group. The high dose of G. arborea extract showed comparable results in parameters like reducing inflammation, percentage inhibition of paw edema and dry granuloma weight in acute carrageenan paw edema and sub-acute inflammation cotton pellet granuloma models with standard aspirin treated group.Conclusions: Since G. arborea root extract was having all the qualities required for anti-inflammatory drug. However, no clear inference can be drawn at this stage and hence we consider the work for further extensive research.

Aim: In the current investigation, tablet dosage form of hydroalcohol extract of leaves of P. emblica was developed and evaluated foranti-inflammatory activities. Methodology: Hydroalcohol extract of leaves of P. Emblica (HPE) was prepared and formulated tablet dosage form. The mechanical properties e.g. hardness, friability, disintegration, and dissolution of tablet were evaluated. Anti-inflammatory activities of HPE (150 mg/kg) and HPE (650 mg) tablets were performed in carrageenan induced hind paw edema in wistar rats. Results: The anti-inflammatory activity was found to be significant in carrageenan inducedpaw edema. HPE (150 mg/kg) and HPE tablets (650 mg) were significantly (p < 0.05) reduced the carrageenan induced paw edemaby 66.41% and 69.43% respectively as compared to                carragenan control. The % inhibition of standard drug (dichlorofenac sodium) was recorded to be 70.18% after 5 h. Conclusion: The study standardised the development of HPE tablet and its anti-inflammatory effect.
