Plants of the genus Argyreia have ethnomedicinal importance, and several pharmacological activities are also reported. In this study, the anti-inflammatory activity of different extracts of Argyreia imbricata was evaluated by in vitro and in vivo methods. In both evaluations, standard, Diclofenac sodium was used for comparative evaluation. In this study, extraction of powdered whole plant material was done with different solvents viz., petroleum ether, chloroform, ethyl acetate and methanol by soxhelation. In vitro anti-inflammatory activity of all the prepared extracts was evaluated by stabilization of human red blood cell (HRBC) membrane in different temperature and tonicity conditions. Among the six different concentrations of four tested extracts, the ethyl acetate and methanol extracts (1000μg/ml) showed significant activity in the in vitro evaluation. They were selected for the in vivo evaluation on the paw oedema induced by carrageenan on Wistar albino rats. Two doses, 200mg.kg-1 and 400mg.kg-1 of the test extracts were subjected to evaluation. Both the tested extracts showed the activity, particularly, the methanol extract in the dose of 400mg.kg-1 showed significant activity. Results of this study strongly supported the anti-inflammatory activity of the tested extracts. Further, studies on toxicity, identification, isolation of the active constituents may give useful results.

Background: Operculina turpethum (Linn.) Silva Manso, family- convolvulaceae, is an important plant in Indian conventional system of medicine which is extensively employed by different tribes in many countries to cure edema and painful conditions like arthritis, back pain; hyperlipidemia, diabetes mellitus, liver disorders, skin disorders and to regulate bowel functions. Objective: The roots of O. turpethum (Linn.) was subjected to physicochemical, phytochemical standardization, the chromatographic separation which was accomplished by column chromatography, TLC, and HPTLC, further, the acute toxicity, cytotoxic and anti-inflammatory activities of Operculina turpethum roots were estimated by in vivo and in vitro models. Materials and Methods: This study includes percentage yield of extraction, organoleptic evaluation along with the analysis of its physicochemical investigations & preliminary phytochemical estimation. The isolation of active phytoconstituents was done by column chromatography, and the isolated compound was then exposed to TLC and HPTLC analysis. Cytotoxic activity was tested by WST-1 based cell viability assay on HepG2 cells. Anti-inflammatory activity of methanol extract (ME) was evaluated against inflammation occur by both in vitro and in vivo method. Results: The methanolic extract exhibited the presence of most of the phytoconstituents out of all the extracts, the phytoconstituent phytosterol, i.e., β-sitosterol was isolated by column chromatography, identified and quantified by TLC and HPTLC, which is liable for anti-inflammatory activity. The amount of β-sitosterol was estimated to be 14.09 µg in 10.00 mg fraction of MEOT. MEOT is devoid of toxicity up to 2000 mg/kg in Wistar albino rats. It was analysed that in vitro anti-inflammatory activity of MEOT by egg albumin denaturation method exhibited a incredible decrement in turbidity and increasing the percentage inhibition of albumin denaturation (60.52%) in MEOT treated group as compared with control group. In egg albumin-induced edema in rats, MEOT at the dose of 400 mg/kg reduced the edema formation (3.03 ± 0.02) induced by egg albumin at 4th h. In cotton pellet-induced granuloma in rats, MEOT at the dose of 400 mg/kg displayed maximum granuloma inhibition (51.06%) which is similar to that of indomethacin. Conclusion: From the obtained findings it is confirmed that O. turpethum contains β-sitosterol which is responsible for potent anti-inflammatory activity without causing cytotoxicity to the plant. The results suggested that ME of O. turpethum roots had high potential for application as an anti-inflammatory agent. The recognization and confirmation of the plant can be obtaineded from the study and will present data which is aidful in determining the quality and purity of a crude drug which further helps in preventing its adulteration.

In this study, we aimed at evaluating in vitro and in vivo anti-inflammatory activity of various extracts of the rhizomes of Globba pendula Roxb. Three extracts ( n-hexane, ethyl acetate, and water) were screened for their inhibitory effect on NO production by lipopolysaccharide-stimulated RAW 264.7 macrophages. The ethyl acetate extract of G. pendula rhizomes (EGP) showed a potential effect with an IC50 value of 32.45 µg/mL. For in vivo study, the ethyl acetate extract was further investigated for its anti-inflammatory effect using collagen antibody-induced arthritic mice (CAIA). The level of arthritis in experimental mice significantly reduced ( P < .05) after treatment with EGP at a dose of 500 mg/kg body weight (b.w.). This study also revealed that EGP is orally non-toxic. Ethyl p-methoxy cinamate was identified as the main constituent of EGP, which may result in its anti-inflammatory effect.

Objective: The objective of the study was to establish the anti-inflammatory and anti-arthritic potential of various fractions of Eclipta prostrata Linn. Methods: The four fractions, i.e., n-butanol, ethyl acetate, chloroform, and n-hexane from hydro-alcoholic extract were obtained. First, the fractions were evaluated through in vitro models, and then they were evaluated by in vivo anti-inflammatory model, i.e., carrageenan-induced paw edema model. Further, two active fractions were evaluated for the anti-arthritic activity using formaldehyde induced arthritis model. Results: The fractions at a dose of 100 and 200 mg/kg showed an anti-inflammatory activity, but the ethyl acetate and chloroform fraction will show maximum anti-inflammatory potential. Hence, they are further evaluated for anti-arthritic potential where they show significant activity. Conclusion: From the results, it is concluded that the ethyl acetate and chloroform fraction show significant anti-arthritic activity.

In our present study, various concentrations of pet ether extract of whole plant of Hyptis suaveolens were prepared and subjected for anti arthritic and anti-inflammatory activity by in vitro methods. The antiarthritic activity was carried out by bovine serum albumin denaturation paradigm. The results showed that the pet ether extract (44.51%) showed excellent arthritic activity when compared to the standard diclofenac sodium (31.44%) at 2000μg/mL. Meanwhile, in the anti-inflammatory paradigm, the same extract (99.10%) showed excellent activity than the standard diclofenac sodium (73.80%) at 2000μg/ mL by restoring the stability of degraded red blood corpuscles. In both the paradigms, increase in concentration of the extract increases the action potential against the methanol degradation of bovine albumin and HRBC.

Formulation of meloxicam gel for topical application: In vitro and in vivo evaluation Skin delivery of NSAIDs offers several advantages over the oral route associated with potential side effects. In the present investigation, topical gel of meloxicam (MLX) was formulated using N-methyl pyrrolidone (NMP) as a solubilizer and Carbopol Ultrez 10® as a gelling polymer. MLX gel was evaluated with respect to different physicochemical parameters such as pH, viscosity and spreadability. Irritation potential of MLX gel was studied on rabbits. Permeation of MLX gel was studied using freshly excised rat skin as a membrane. Anti-inflammatory activity of MLX gel was studied in rats and compared with the commercial formulation of piroxicam (Pirox® gel, 0.5% m/m). Accelerated stability studies were carried out for MLX gel for 6 months according to ICH guidelines. MLX gel was devoid of any skin irritation in rabbits. After 12 h, cumulative permeation of MLX through excised rat skin was 3.0 ± 1.2 mg cm-2 with the corresponding flux value of 0.24 ± 0.09 mg cm-2 h-1. MLX gel exhibited significantly higher anti-inflammatory activity in rats compared to Pirox® gel. Physicochemically stable and non-irritant MLX gel was formulated which could deliver significant amounts of active substance across the skin in vitro and in vivo to elicit the anti-inflammatory activity.

Abstract Background Justicia secunda Vahl. is a medicinal plant used in ethnomedical practice as therapy to manage inflammation. Therefore, this study was designed to evaluate the anti-inflammatory activity of methanol extract of J. secunda leaves (MEJSL) using in vitro and in vivo inflammation models. Methods Seventy-percent MEJSL was prepared following standard procedure. In vitro anti-inflammatory assays were performed using heat-induced bovine serum albumin (BSA) denaturation and erythrocyte membrane stabilization assays. Carrageenan and formaldehyde induced inflammation in rat models were used to evaluate the anti-inflammatory activity of MEJSL in vivo. Diclofenac sodium was used as a reference drug. In addition, liver and kidney function assays and hematological analysis were carried out. Results Data revealed that varying concentrations of MEJSL significantly (P < 0.05) inhibited heat-induced BSA denaturation and stabilized erythrocyte membrane against hypotonicity-induced hemolysis when compared with diclofenac sodium in a concentration-dependent manner. In vivo study showed that 10 mg/kg body weight (b.w.) diclofenac sodium, 100 and 300 mg/kg b.w. MEJSL suppressed carrageenan-induced paw edema at the sixth hour by 71.14%, 83.08%, and 89.05%, respectively. Furthermore, 10 mg/kg b.w. diclofenac sodium, 100 and 300 mg/kg b.w. MEJSL inhibited formaldehyde-induced paw edema by 72.53%, 74.73%, and 76.48%, respectively. Animals treated with varying doses of MEJSL had reduced plasma aspartate aminotransferase and alanine aminotransferase activities; urea and creatinine concentrations; and modulated hematological parameters when compared with the untreated control group. Conclusions Findings from this study showed that MEJSL exhibited substantial anti-inflammatory actions in the in vitro and in vivo models. It also indicated that MEJSL anti-inflammatory mechanisms of action could be through interference with phase 2 inflammatory stressors, upregulation of cytoprotective genes, stabilization of inflammatory cell membranes and immunomodulatory activity.

In the present study, the potential effects of extracts from the whole plant of Cuscuta arvensis were studied in mice using the carrageenan-induced hind paw edema model for anti-inflammatory activity and the p-benzoquinone-induced writhing reflex for the assessment of antinociceptive activity. In order to obtain the extracts, the whole plant of C. arvensis was extracted with different solvents such as n-hexane, dichloromethane, ethyl acetate, methanol and distilled water. Antioxidant activity was evaluated by the 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assay. The methanolic and water extracts inhibited the carrageenan-induced paw edema and p-benzoquinone-induced writhing reflex, whereas the other extracts showed only mild inhibitory antinociceptive and anti-inflammatory activities in these in vivo models. Additionally, the methanol and ethyl acetate extracts had higher scavenging ability then the non polar extracts.

Naproxen, an anti-inflammatory drug, exhibits poor aqueous solubility, which limits the pharmacological effects. The present work was carried out to study the effect of agglomeration on micromeritic properties and dissolution. Naproxen agglomerates were prepared by using a three solvents system composed of acetone (good solvent), water (non-solvent) and dichloromethane (bridging liquid). Differential Scanning Calorimetry (DSC) results showed no change in the drug after crystallization process. X-Ray Powder Diffraction (XRPD) studies showed the sharp peaks are present in the diffractograms of spherical agglomerates with minor reduction in height of the peaks. The residual solvents are largely below the tolerated limits in the agglomerates. Scanning Electronic Microscopy (SEM) studies showed that agglomerates were spherical in structure and formed by cluster of small crystals. The agglomerates exhibited improved solubility, dissolution rate and micromeritic properties compared to pure drug. Anti-inflammatory studies were conducted in Wistar strain male albino rats and naproxen agglomerates showed more significant activity than the pure drug.
