Marrubium vulgare (Lamiaceae) is frequently used in traditional medicine to treat many illnesses from ancient times. Its beneficial effects include antibacterial, antioedematogenic, and analgesic activities. This study was designed to evaluate the antioxidant and anti-inflammatory activities of organic and aqueous extracts of the leaves, the flowers, the stems, and the roots of Marrubium vulgare. The total phenolic and flavonoid contents as well as the antioxidant and the anti-inflammatory effects of methanol, chloroform, ethyl acetate, and aqueous extracts have been investigated by using different in-vitro methods. It was found that the ethyl acetate extract from Marrubium vulgare stems had the highest total phenolic content, while the ethyl acetate extract from the leaves yielded a high concentration of flavonoids. The ethyl acetate extract from the stems exhibited the highest activity in scavenging of 2,2-diphenyl- 1-picrylhydrazyl (DPPH), as well as in protecting erythrocytes. The leaves aqueous extract exhibited the highest ferrous chelating activity and its methanolic extract was found to be the strongest inhibitor of lipid peroxidation in β-carotene bleaching assay. The leaves chloroform extracts as well as the flowers methanol, chloroform, and ethyl acetate extracts were found to decrease the pro-inflammatory tumor necrosis factor alpha (TNF-α) cytokine levels in a dose-dependent manner. On the other hand, the flowers methanolic extract and the leaves methanol, ethyl acetate, and aqueous extracts decreased the interleukin-1 beta (IL- 1β) release. It was also found that the methanol extract from the flowers and the chloroform extract from the stems of Marrubium vulgare inhibited interleukin-8 (IL-8) release. This study provides a scientific basis for the traditional use of Marrubium vulgare as an anti-inflammatory agent and for the plant to be considered as an important resource of natural antioxidants.

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.

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.

Kencur (Kaempferia galanga L.) is a family of Zingiberaceae. Several studies have shown that kencur can help reduce inflammation because kencur is known to contain anti-inflammatory compounds, namely marker compounds from flavonoids, kaempferol. For the development of pharmaceutical preparations, research on anti-inflammatory plasters containing 96% ethanol extract, n-hexane extract, ethyl acetate extract and 70% ethanol extract from ginger rhizome with the addition of penetration enhancer (enhancer), namely propylene glycol. This anti-inflammatory plaster was tested for its activity in 5 groups of Wistar strain rat feet which had been induced 1% carrageenan (negative control); positive control (diclofenac sodium), ethanol96% extract, n-hexane extract, ethyl acetate extract and 70% ethanol extract from kencur rhizome and compared with plaster of kencur rhizome ethanol extract without enhancer. The results showed the effect of adding enhancers 30 minutes after administration. 96% ethanol extract and ethyl acetate extract had reduced inflammation by 79.99% in rat test animals compared to plaster ethanol extract of rhizome kencur without the addition of enhancers. Keywords :  Kaempferia galanga.

Objective: The present study was aimed to rationalize the scientific basis in traditional use of Eranthemum capense as an antibacterial, antifungal, and anti-inflammatory agent. Methods: Agar well diffusion method is widely used to evaluate the antimicrobial activity of the E. capense aerial part of methanolic and ethyl acetate plant extracts. The same amount (15–20 mL) of Mueller-Hinton agar was poured on glass Petri plates of same size and allowed to solidify. E. capense aerial part of methanolic and ethyl acetate extracts was evaluated in vitro for their anti-inflammatory activities using the bovine serum albumin protein denaturation assay. Results: The result of the study shows that methanolic exract (T3) of the plant, E. capense shows 16 mm zone of inhibition against Pseudomonas fluorescens, while the ethyl acetate extract of the same plant shows 14 mm zone of inhibition against P. fluorescens and E. coli. Hence the methanolic extract of T3 sample shows the antibacterial activity against gram negative bacteria, where as the ethyl acetate extract of T3 shows antibacterial activity against both gram positive and gram negative bacteria. The experimental report revealed that, the methanolic and ethyl acetate extract of the same plant produces zero percentage zone of inhibition against Aspergillus niger and Mucor, hence it does not show any antifungal activity. Conclusion: It is observed that the EA and methanolic extract of E. capense can be used in the treatment of inflammation due to the significant percentage of inhibition of protein denaturation as well as its prove the good antimicrobial agent.
