Objective: The aim of the research work was to carry out the extraction of areal parts of Biden pilosa L by hydroalcholic and Hexane, ethyl acetate and acetone mixture followed by qualitative phytochemical analysis, acute oral toxicity test, anti-inflammatory test and GC-MS analysis of the extracts. Method: The hydro-alcoholic and HEA(n-hexane, ethyl acetate and acetone) extraction was done from aerial parts using ethanol and water in the ratio 70:30 and n-hexane, ethyl acetate and acetone in the ratio of 1:1:1 (HEA extract)  respectively. Acute oral toxicity testwas performed OECD guidelines. The single spot in TLC was obtained using n-hexane as solvent for HEA fraction and finally phytocomponents were identified by GC-MS present in that spot.In vitro anti-inflammatory activity was performed by human RBC membrane stabilization method. Result: The phytochemical test results obtained indicate that hydro-alcoholic extract of aerial part of Bidens pilosa L. possess alkaloids, tannins, terpenoids and saponins whereas HEA extract possess alkaloids, flavonoids, tannins. Both hydro-alcoholic and HEA extracts were found to be safe up to the dose of 2000 mg/kg BW of the mice. Both extracts showed significant in vitro anti-inflammatory activity in a concentration dependent manner. The GC-MS analysis of HEA extract of aerial parts showed the presence of the sixteen different compounds from partially separated extract from TLC plates. Conclusion: Hydro-alcoholic extract of aerial part of Bidens pilosa L. possess alkaloids, tannins, terpenoids and saponins whereas HEA extract possess alkaloids, flavonoids, tannins. Both hydro-alcoholic and HEA extracts were found to be safe up to the dose of 2000 mg/kg BW of the mice. The GC-MS analysis of HEA extract of aerial parts showed the presence of the sixteen different compounds.

The main aim of the work was to scientifically prove the anti-inflammatory property of the polyphenol-rich fraction of hydro-alcoholic leaf extract of Litsea quinqueflora (Dennst.) Suresh by protein denaturation and free radical scavenging activity. The polyphenol-rich fraction of hydro-alcoholic leaf extract was obtained via acid-alkali hydrolysis, followed by fractionation with chloroform and ethyl acetate. HPTLC profiling of the finally obtained ethyl acetate fraction and consequent derivatisation with aluminium chloride revealed the presence of flavonoids in a more purified form. LCMS/MS analysis tentatively identified the presence of bioactive polyphenolic compounds such as gallocatechin, sinapic acid, pinocembrin, paeonol and umbelliferone in the separated fraction. The polyphenol-rich fraction of hydro-alcoholic extract of leaves showed anti-denaturing activity in heat-induced bovine serum albumin denaturation with an IC50 value of 23.59 µg/ml and was statistically significant at 0.1% level. The antioxidant property of the polyphenol-rich fraction determined by its free radical scavenging ability against DPPH and ABTS showed IC50 values 122.98 and 135.44 µg/ml respectively and was also statistically significant at 0.1% level. Hence, the traditional use of Litsea quinqueflora as an anti-inflammatory agent can be attributed to the presence of polyphenols.

In this study, the anti-inflammatory effect of aqueous alcoholic crude extract and ethyl acetate extract of miswak sticks (Salvadora persica L.) was investigated in carrageenan induced rat paw oedema in respect to immunological parameters. Adult male sapargue dawely rats were classified into four groups, group I received the vehicle (0.25% gum acacia solution), group II received crude aqueous alcoholic extract orally at 100 mg/kg, group III received ethyl acetate extract (100 mg/kg) orally and group IV received indomethacin (20 mg/kg) orally, and served as standard reference. The oedema was quantified by measuring the hind paw thickness immediately before subplantar injection, and at 1, 2, 3 and 4 h. Blood samples were withdrawn after the 4th hour of carrageenan induction, centrifuged and sera were used for analysis of pro-inflammatory cytokines. Administration of aqueous alcoholic extract and ethyl acetate extract (100 mg/ml) significantly reduced the oedema thickness in a time dependent manner, the inhibition percentage of inflammation was 17% for crude extract and 27% for ethyl acetate extract. Also the two extracts reduced secretion of inflammatory mediators, interleukin-1β (IL-1β), IL-6, tumor nercrosis factor-α (TNF-α) and transforming growth factor-β1 (TGF-β1) in serum. The ethyl acetate extract shows potent activity to be nearly the same of indomethacin activity on all determined parameters at the last hour of following up. These results may be due to the presence of flavonoids in ethyl acetate extract. Three major flavonoids were isolated from ethyl acetate extract and identified as apigenin rhamnoglucoside, luteolin glucoside and rutin. The experimental study revealed that Salvadora persica extracts display remarkable anti-inflammatory activity.

Aims: The present investigation was aimed at exploring the phytoconstituents using Gas Chromatography Mass Spectroscopy and to evaluate antioxidant and anti-inflammatory properties of the leaf extracts. Materials and Methods: The extracts were obtained sequentially with petroleum ether, ethyl acetate and water using soxhlet apparatus. The anti-inflammatory property of the identified compounds using GC- MS spectroscopy was evaluated in silico. The antioxidant activity was performed by DPPH and H2O2 method whereas anti-inflammatory study was carried out by HRBC membrane stabilization method. Terpenoids were found to be major constituents in petroleum ether extract while, phenols and flavonoids were predominantly found in ethyl acetate extract. Results and Discussion: The GC-MS analysis of the extract revealed six major molecules including Squalene, 19β, 28- epoxyleanan-3-ol and 2-tu-Butyl-5-chloromethyl-3-methyl-4-oxoimidazolidine-1-carboxylic acid. The ethyl acetate extract showed a significant antioxidant activity (P<0.01) in both DPPH method (70.87 %) and H2O2 method (73.58%) at 200 µg mL-1 . Increased membrane stabilization of petroleum ether extract was observed in the in vitro anti-inflammatory activity study. A strong relationship between the terpenoid content and anti-inflammatory activity was obtained from the correlation (0.971) and docking study. Conclusion: These results justify T. involucrata to be a rich source of terpenoids with potent antiinflammatory property.

Mouse Ear Edema

Nowadays, there is a growing interest in the development of medicinal plant-based therapies to diminish the ravages of the inflammatory process related to diseases and tissue damage. Most therapeutic effects of these traditional medicinal plants are owed to their phenolic and antioxidant properties. C. aconitifolius is a traditional medicinal plant in Mexico. Previous characterization reports have stated its high nutritional and antioxidant components. The present study aimed to better understand the biological activity of C. aconitifolius in inflammation response. We developed an ethyl acetate extract of this plant to evaluate its anti-inflammatory capacity and its flavonoid content. The topical anti-inflammatory effect of the ethyl acetate extract of C. aconitifolius was determined by the croton oil-induced mouse ear edema test, while flavonoid detection and concentration were determined by thin layer chromatography and the aluminum chloride colorimetric assay, respectively. Topical application of the extract showed significant inhibition of the induced-ear edema (23.52 and 49.41% for 25 and 50 mg/kg dose, respectively). The extract also exhibited the presence of flavonoids. The finding of the anti-inflammatory activity exerted by the C. aconitifolius and the identification of its active principles may suggest and support its use for inflammation treatment.
