This study aimed to isolate, prepare and identify the main flavonoids from a standardized Smilax glabra flavonoids extract (SGF) using preparative HPLC, MS, 1H NMR and 13C NMR, determine the contents of these flavonoids using UPLC, then compare their pharmacological activities in vitro. We obtained six flavonoids from SGF: astilbin (18.10%), neoastilbin (11.04%), isoastilbin (5.03%), neoisoastilbin (4.09%), engeletin (2.58%) and (−)-epicatechin (1.77%). The antioxidant activity of six flavonoids were evaluated by determining the 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical and 2,2′-Azinobis (3-ethylbenzothiazoline-6-sulphonic acid) diammonium salt (ABTS+) radical scavenging activity and ferric reducing antioxidant power (FRAP). In addition, the anti-inflammatory activity of six flavonoids were evaluated by determining the production of cytokines (IL-1β, IL-6), nitric oxide (NO) using enzyme linked immunosorbent assay and the NF-κB p65 expression using Western blotting in lipopolysaccharide (LPS)-stimulated RAW264.7 cells. The results showed that (−)-epicatechin, astilbin, neoastilbin, isoastilbin and neoisoastilbin had strong antioxidant activities, not only in DPPH and ABTS+ radicals scavenging capacities, but in FRAP system. Furthermore, all the six flavonoids could significantly inhibit the secretion of IL-1β, IL-6, NO (p < 0.01) and the protein expression of NF-κB p-p65 (p < 0.01) in LPS-stimulated RAW264.7 cells. This study preliminarily verified the antioxidant and anti-inflammatory activities of six flavonoids in S. glabra.

Inflammation is a double-edged sword, as it can have both protective effects and harmful consequences, which, combined with oxidative stress (OS), can lead to the development of deathly chronic inflammatory conditions. Over the years, research has evidenced the potential of marine sponges as a source of effective anti-inflammatory therapeutic agents. Within this framework, the purpose of this study was to evaluate the antioxidant and the anti-inflammatory potential of the marine sponge Cliona celata. For this purpose, their organic extracts (C1–C5) and fractions were evaluated concerning their radical scavenging activity through 2,2-diphenyl-1-picrylhydrazyl radical (DPPH), ferric reducing antioxidant power (FRAP), oxygen radical absorbance capacity (ORAC), and anti-inflammatory activity through a (lipopolysaccharides (LPS)-induced inflammation on RAW 264.7 cells) model. Compounds present in the two most active fractions (F5 and F13) of C4 were tentatively identified by gas chromatography coupled to mass spectrometry (GC-MS). Even though samples displayed low antioxidant activity, they presented a high anti-inflammatory capacity in the studied cellular inflammatory model when compared to the anti-inflammatory standard, dexamethasone. GC-MS analysis led to the identification of n-hexadecanoic acid, cis-9-hexadecenal, and 13-octadecenal in fraction F5, while two major compounds, octadecanoic acid and cholesterol, were identified in fraction F13. The developed studies demonstrated the high anti-inflammatory activity of the marine sponge C. celata extracts and fractions, highlighting its potential for further therapeutic applications.

 Objectives: A persistent and chronic inflammation may act as an underlying definition for many of the long-term illness such as diabetic foot ulcer, Alzheimer’s disease and rheumatoid arthritis. Folklore medicinal plants provide immense health benefits with new remedies. Active compounds from plants containing alkaloids and phenolic compounds (flavonoids and tannins) possess antioxidant and anti-inflammatory activity. The leaves of Adhatoda vasica are most known for its effectiveness in treating respiratory diseases such as asthma, chronic bronchitis, and other respiratory conditions. In this report, we investigated the possible action of A. vasica against inflammation.Methods: Solvents with varying polarity (Hexane, dichloromethane, ethyl acetate, and methanol) were used for the sequential extraction of leaves of A. vasica Linn (Family: Acanthaceae). The anti‐inflammatory activity was assessed using simple in vitro methods. Phenols, flavonoids, phytosterols, saponins, alkaloids, and tannins were analyzed qualitatively using standard protocols. Anti‐inflammatory activity was evaluated using albumin denaturation assay, membrane stabilization assay and proteinase inhibitory activity. Aspirin (diclofenac) was used as a standard drug for the study of anti-inflammatory activity.Results: Our results substantiated that methanolic extract of A. vasica gave a maximum yield of 12.5% and apparently all bioactive phytochemical constituents were at a higher concentration in the methanolic extract. Methanolic extract of A. vasica showed a significant inhibition of the heat-induced albumin denaturation, red blood cells membrane stabilization, and proteinase inhibitory effects with 86±1.46, 88±1.24, and 96±0.93% for 1000 μg/ml, respectively.Conclusion: The above results delineate that the bioactive components were extracted using high polar solvent are mostly flavonoids and related polyphenols. These compounds may be the active constituents to render the anti-inflammatory activity to A. vasica.

Objective: This study aims to evaluate the in vitro antioxidant, anti-inflammatory activities of the aqueous and hydroethanolic extracts recipe of Alchornea cordifolia and Antrocaryon klaineanum. A preliminary phytochemical screening was carried out. Methods: The total phenols content was determined by the Folin Ciocalteu reagent method, while the antioxidant activity of both extracts was characterized by the 2-2diphenyl-1-picrilhidrazil (DPPH) and β-carotene assays. The anti-inflammatory activity of the extracts was evaluated as the inhibition of Bovine Serum Albumin (BSA) denaturation and antiproteinase activity. Results: The aqueous extracts of Alchornea cordifolia and Antrocaryon klaineanum contained more polyphenols [270 mg Ascorbic acid equivalent (AAE)/g dry weight (dw)] than the hydroethanolic recipe extract (262.41 mg AAE/g dw) at the same concentration level. On the other hand, the aqueous and hydroethanolic recipe extract had the same radical scavenging activity with the antiradical power of 0.851 and 0.830, respectively. Similarly, the recipe extract had the same reducing activity with reducing the power of 94.2±2.03 mg EAA/g dw and 97.4±4.16 mg EAA/g dw for the aqueous and hydroethanolic recipe extract of Alchornea cordifolia and Antrocaryon klaineanum respectively. For the anti-inflammatory activity it was observed that both extracts possess the same activity as Diclofenac® with an IC50 of 50.21 μg/ml. The phytochemical screening of the extracts revealed the presence of alkaloids, flavonoids, carbohydrates, phenols and tannins, which may account for their activities. Conclusion: The plant recipe extract studied possess antioxidant and anti-inflammatory potentials, which may be beneficiary to its consumers.
