Physalis peruviana calyces are used extensively in folk medicine. The crude ethanolic extract and some fractions of calyces were evaluated in order to explore antioxidant and anti-inflammatory activities. The anti-inflammatory activity was evaluated by the TPA-induced ear edema model. The antioxidant in vitro activity was measured by means of the superoxide and nitric oxide scavenging activity of the extracts and fractions. The butanolic fraction was found to be promising due to its anti-inflammatory and antioxidant activities. Therefore, a bio-assay guided approach was employed to isolate and identify rutin (1) and nicotoflorin (2) from their NMR spectroscopic and MS data. The identification of rutin in calyces of P. peruviana supports the possible use of this waste material for phytotherapeutic, nutraceutical and cosmetic preparations.

Inflammatory Effect

Background: Anchusa azurea Mill. (AA) is a medicinal plant largely used traditionally in folk medicine in Algeria, it is locally named: hamham. It is effective in the treatment of various diseases. Objectives: The aim of the present study is to determine the antioxidant, anti-inflammatory and anti-hemolytic effects of phenolic fractions from Anchusa azurea Mill. Methods: In this study, various extracts from Anchusa azurea Mill. (AA) using solvents with increasing polarity were prepared. The quantification of polyphenols and flavonoids was determined. The anti-radical activity of the different extracts was evaluated using DPPH and by measuring the inhibition of the oxidative degradation of β-carotene. The In vitro antihemolytic effect of the plant extracts is determined (CrE, ChE, AcE and AqE). For each extract, four concentrations were tested: 10.59, 21.18, 42.37, 84.74 µg/ml. Vitamin C is used as a standard. Free-radical attack was measured by measuring the HT50 (Half-Hemolysis Time). The anti-inflammatory effect using PMA on mice of the methanolic extract (CrE) was evaluated. Results: The quantification of polyphenols and flavonoids showed that ethyl acetate extract (AcE) contains a higher amount of polyphenols. However, chloroform extract (ChE) presents a higher amount of flavonoids. AcE showed an important scavenging activity using the DPPH radical (IC50= 68.35 µg/ml). The results showed that AcE also exhibited very great inhibition on the oxidation of β-carotene/linoleic acid (84.33%). All extracts increased the HT50 values (Half-Hemolysis Time) in a dose-dependent manner. The three highest concentrations (21.18, 42.37 and 84.74 µg / ml) of ChE caused a very significant delay (p ≤ 0.001) of hemolysis compared to the negative control and the positive control "VIT C". The anti-inflammatory effect using PMA on mice showed that the methanolic extract (CrE) of AA reduced the weight of the ear edema. Conclusions: This plant has a strong pharmacological power, which supports its traditional medicinal use.

Veronicastrum axillare is a traditional medical plant in China which is widely used in folk medicine due to its versatile biological activities, especially for its anti-inflammatory effects. However, the detailed mechanism underlying this action is not clear. Here, we studied the protective effects of V. axillare against acute lung injury (ALI), and we further explored the pharmacological mechanisms of this action. We found that pretreatment with V. axillare suppressed the release of proinflammatory cytokines in the serum of ALI mice. Histological analysis of lung tissue demonstrated that V. axillare inhibited LPS-induced lung injury, improved lung morphology, and reduced the activation of nuclear factor-κB (NF-κB) in the lungs. Furthermore, the anti-inflammatory actions of V. axillare were investigated in vitro. We observed that V. axillare suppressed the mRNA expression of interleukin-1β (IL-1β), IL-6, monocyte chemotactic protein-1 (MCP-1), cyclooxygenase-2 (COX-2), and tumor necrosis factor-α (TNF-α) in RAW264.7 cells challenged with LPS. Furthermore, pretreatment of V. axillare in vitro reduced the phosphorylation of p65 and IκB-α which is activated by LPS. In conclusion, our data firstly demonstrated that the anti-inflammatory effects of V. axillare against ALI were achieved through downregulation of the NF-κB signaling pathway, thereby reducing the production of inflammatory mediators.

Lobelia chinensis Lour (LcL) is a popular herb that has been widely used as folk medicine in China for the treatment of fever, lung cancer, and inflammation for hundreds of years. Recently, several studies have shown that the anti-inflammatory properties were correlated with the inhibition of inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) from the NF-κB pathway. The aim of this study was to evaluate the anti-oxidative and anti-inflammatory activities of L. chinensis. Both suppressive activities on LPS-induced nitric oxide production in RAW264.7 macrophages in vitro and the acute rat lung injury model in vivo were studied. The results showed that the methanol extract of LcL and its fractions within the range of 62.5–250 μg/mL did not induce cytotoxicity (p < 0.001). The ethyl acetate fraction of LcL showed better NO inhibition activity than other fractions. On the other hand, the Lc-EA (62.5, 125, 250 mg/kg) pretreated rats showed a decrease in the pro-inflammatory cytokines (TNF-α, IL-β, IL-6) and inhibited iNOS, COX-2 expression through the NF-κB pathway. These results suggested that L. chinensis exhibited an anti-inflammatory effect through the NF-κB pathways.

SummarySymptoms of inflammation accompany a number of diseases. In order to mitigate them, folk medicine has used a variety of medicinal substances, including herbs and mushrooms. Lichens are less known organisms, containing specific secondary metabolites with interesting biological properties. One of their biological actions is the anti-inflammatory activity that has been confirmed byin vitroand animal studies. It has been proven that compounds and extracts from lichens inhibit the enzymes involved in the inflammatory process. The following paper is a review of research on the little-known anti-inflammatory properties of lichens.
