Objective: The present study was carried out to investigate the in vitro anti-inflammatory activity of syringic acid (SA).  Methods: SA was tested for it's in vitro anti-inflammatory activity at different concentrations in protein denaturation, proteinase inhibition and human red blood cell (HRBC) membrane stabilization assay. The reference drugs used were aspirin and diclofenac sodium. Results: SA showed concentration-dependent inhibition of protein denaturation and proteinase activity with a half-maximal inhibitory concentration (IC50) value of 49.38±0.56 µg/ml and 53.73±0.27 µg/ml respectively. Heat-induced haemolysis was inhibited by SA with an IC50 value of 57.13±0.24 µg/ml. SA also inhibited the hypotonicity-induced haemolysis (IC50 value of 53.87±0.72 µg/ml). Conclusion: From the present study, we can conclude that SA possesses appreciable anti-inflammatory effect against denaturation of proteins, proteinase activity, and human red blood membrane stabilization assays. Further studies are required for determining the possible mechanisms behind its anti-inflammatory action.

The present research work aimed at evaluating the anti-inflammatory activity of Zingiber officinalis with Diclofenac sodium by HRBC membrane stabilization & Protein denaturation. The precluding of hypotonicity induced HRBC membrane lysis was taken as a measure of the anti-inflammatory activity. The percentage of membrane stabilization at different concentrations was performed for methanolic, hydro-methanolic ginger extract and diclofenac sodium. At a dose of 50µg/ml the maximum membrane stabilization 86.34% was found for Ginger extract(test) and at a dose of 500 mcg/ml membrane stabilization was found 91.16% for diclofenac sodium(standard) and the membrane stabilization for combination (ginger with diclofenac sodium) at a dose of 50µg/ml was recorded 86.43%, as the concentration increase(1000 mcg/ml) for combination(ginger with diclofenac sodium) the percentage protection was decreased. In vitro protein denaturation was performed by using egg albumin method. Maximum inhibition was observed in case of methanolic extract of ginger at concentration 1000mcg/ml and it was 78.83±5.17 and in hydro methanolic extract for Diclofenac sodium at concentration 1000mcg/ml and it was 63.37±2.78.Minimum inhibition observed in combination of methanolic extract of ginger and diclofenac sodium at concentration 1000mcg/ml and it was 25.27±1.76 and in combination of hydro-methanolic extract of ginger and Diclofenac sodium at concentration 1000mcg/ml and it was 28.23±3.14. The results of this study divulge that low dose combination of ginger and diclofenac sodium has higher anti-inflammatory activity than diclofenac sodium and ginger alone. With this initial study, research work could be extended further; therefore, the particular pharmacological action for the combination of ginger with diclofenac sodium could be discovered.

<p><strong>Objective: </strong>To evaluate the potential antioxidant, anti-inflammatory and antibacterial activities of aqueous and methanolic extracts of leaves of <em>Leucas aspera</em> (Thumbae).</p><p><strong>Methods: </strong>Phytochemical screening of the leaves of <em>L. aspera</em> was followed by analysis of antioxidant activity by means of DPPH (2, 2-diphenyl-1-picrylhydrazyl) radical scavenging activity. <em>In vitro</em> anti‐inflammatory activity was evaluated using lipoxygenase inhibition, albumin denaturation assay, membrane stabilization assay and proteinase inhibitory activity at different concentrations. Aspirin was used as a standard drug for the study of anti‐inflammatory activity. Linear regression analysis was used to calculate half maximal inhibitory concentration, IC50 value. The zone of inhibition was performed against common pathogens to determine the antimicrobial activity at different concentrations of plant extracts (60%, 70%, 80%).</p><p><strong>Results: </strong>The phytochemical analysis revealed the presence of carbohydrates, amino acid, alkaloids, tannins, flavonoids, glycosides, xanthoproteins, and phenols. The total phenolic and flavonoid content was found to be 2.25±0.04 mg GAE/g (gallic acid equivalents) and 1.2±0.05 mg QE/g (Quercetin equivalents) of fresh weight tissue respectively. The IC50 values for hydrogen peroxide scavenging activity were found to be 244.6 µg/ml. The extract inhibited the lipoxygenase enzyme activity with an IC50 value of 356.3 µg/ml. Maximum inhibition of heat-induced protein denaturation of 69% was observed at 400 μg/ml, IC50 249.6 μg/ml. Proteinase activity was also significantly inhibited (IC50 = 421.6 μg/ml). Membrane stabilization assay attributed minor protection by the leaf extract with an IC50 of 206.7. It was observed that <em>E. coli</em> were inhibited at all concentrations, followed by <em>Klebsiella</em> and <em>Pseudomonas</em>.</p><p><strong>Conclusion: </strong>Results indicate that L. aspera possess anti-inflammatory properties due to the strong occurrence of polyphenolic compounds such as alkaloids, flavonoids, tannins and steroids that serve as free radical inhibitors or scavenger. Compounds of the plant L. aspera may hence be used as lead compounds for designing potent anti-inflammatory drug which can be used for treatment of various diseases.</p><p> </p>

In the present study, analysis of in vitro inflammatory showed whole plant of Rhizophora mucronata Lam. (Malpighiales: Rhizophoraceae) can be the potent source. The data from this study showed that the R. mucronata leaf, bark and root extract could serve as an important anti-inflammatory agent. Moreover, among the three extracts, the stilt root and leaves extract showed highest anti inflammatory. In vitro anti-inflammatory activity of the selected plant extracts was evaluated using albumin denaturation, membrane stabilization and proteinase inhibitory assays. As part of the investigation on the mechanism of the anti-inflammation activity, ability of extract protein denaturation was studied. Maximum inhibition (296.26%) was observed from root extract followed by bark (259.48%) and leaf (237.62%). The extracts inhibited the heat induced hemolysis of RBCs to varying degree as show in table below. The maximum inhibition 284.17% was observed from bark extract followed by root (265.05%) and leaf (232.61%). It reveals that these phytochemical constituents are responsible to maximum protection of protein denaturation, albumin denaturation and membrane stabilization assay. The future work will be determination of anti-inflammatory and anti-arthritic activities by in vivo models.

Inflammation might be a complex organic reaction to a hazardous stimulant such as pathogens, or injured tissues and mainly causes itching, swelling, skin redness, warm and slight pain. Herbal drugs are widespread in India for their effectiveness, easy availability at low cost and provide low toxicity as compared to modern drugs. Centella asiatica is one of the oldest Ayurvedic medicinal plants, used in treatment of various skin diseases. The aim of our present research was to evaluate the in vitro anti-inflammatory activity of methanolic extract and different fractions of C. asiatica leaves. In protein denaturation method, the percentage inhibition for methanolic extract was observed to be 40.22%. The petroleum ether and n-butanol fraction of methanolic extract of C. asiatica were observed to exhibits 54.12 and 44.42% inhibition, respectively. Diclofenac sodium was used as a standard drug. In comparison with other fractions petroleum ether and n-butanol fractions showed best activity. The preliminary phytochemical studies of n-butanol fractions and n-butanol fractions showed the presence of terpenoids, flavonoids etc., which are used in the treatment of inflammation. Thus, we can call the latter as intense anti-inflammatory agent.
