Abstract Opuntia ficus-indica extract has been used in traditional folk medicine for several purposes and exhibits anti-inflammatory properties. This study was directed to explore the prophylactic effect of O. ficus-indica fruit peel extract against irradiation-induced colitis in rats. GC/MS analysis of the petroleum ether extract led to recognition of 33 compounds in the unsaponifiable fraction and 15 fatty acid methyl esters in the saponifiable part. Thirteen terpenes and sterols were isolated and identified from which ten compounds were not isolated from any part of this species before. Data showed that irradiation induced colon injury as manifested by elevated contents of malondialdehyde, nitric oxide, myeloperoxidase, intercellular adhesion molecule-1, cyclooxygenase-2, tumor necrosis factor alpha, and nuclear factor kappa B, while it reduced superoxide dismutase activity and interleukin 10 content in colonic tissues, which was confirmed by histopathological examination. Pretreatment with O. ficus-indica extract attenuated the alteration in the measured parameters. It could be concluded that O. ficus-indica fruit peel extract can be regarded as a potential agent in limiting colonic complications due to irradiation, possibly by its antioxidant and anti-inflammatory properties.

Idiopathic pulmonary fibrosis is a progressive fatal lung disease characterized by excessive collagen deposition, with no effective treatments. We investigated the efficacy of natural products with high anti-inflammatory activity, such as passion fruit peel extract (PFPE), in a mouse model of bleomycin-induced pulmonary fibrosis (PF). C57BL/6J mice were subjected to a single intratracheal instillation of bleomycin to induce PF. Daily PFPE treatment significantly reduced loss of body mass and mortality rate in mice compared with those treated with bleomycin. While bleomycin-induced PF resulted in elevated total numbers of inflammatory cells, macrophages, lymphocytes, and neutrophils in bronchoalveolar lavage fluid on both days 7 and 21, PFPE administration significantly attenuated these phenomena compared with bleomycin group. On day 7, the decreased superoxide dismutase and myeloperoxidase activities observed in the bleomycin group were significantly restored with PFPE treatment. On day 21, enhanced hydroxyproline deposition in the bleomycin group was also suppressed by PFPE administration. PFPE treatment significantly attenuated extensive inflammatory cell infiltration and accumulation of collagen in lung tissue sections of bleomycin-induced mice on days 7 and 21, respectively. Our results indicate that administration of PFPE decreased bleomycin-induced PF because of anti-inflammatory and antioxidant activities.

The use of colorants in the dried noodle manufactures is an effort of product diversification. Besides of being used as a natural coloring agent, this peel extract is also used to improve nutritional value of the expected product. The purpose of this study was to determine the effect of red dragon fruit peel extract on the physical quality of dried noodle.  The study was conducted by using Completely Randomized Design (CRD) method with one factor, namely concentration of red dragon fruit peel extract (N1 = 10 ml, N2 = 15 ml, N3 = 20 ml, N4 = 25 ml, N5 = 30 ml).  The observations of its physical quality consisted of water absorption, solid loss during cooking, and organoleptic tests (aroma and color).  The best quality of dried noodle was obtained by using 30 ml red dragon fruit peel extract (N5) with physical properties, namely DSA levels of 351.92%, solid loss during cooking 4.78%, aroma 3.79 (like) and color 3.89 (like).

Apoptotic Effects

Methotrexate (MTX) is frequently used drug in treatment of cancer and autoimmune diseases. Unfortunately, MTX has many side effects including the hepato-renal toxicity. In this study, we hypothesized that Luteolin (Lut) exhibits protective effect against the MTX-induced hepato-renal toxicity. In order to investigate our hypothesis, the experiment was designed to examine the effect of exposure of male rats to MTX (20 mg/kg, i.p., at day 9) alone or together with Lut (50 mg/kg, oral for 14 days) compared to the control rats (received saline). The findings demonstrated that MTX treatment induced significant increases in the liver and kidney functions markers in serum samples including Aspartate transaminase (AST), Alanine transaminase (ALT), creatinine, urea and uric acid. MTX also mediated an oxidative stress expressed by elevated malondialdehyde (MDA) level and decreased level of reduced glutathione (GSH), antioxidant enzyme activities, and downregulation of the Nrf2 gene expression as an antioxidant trigger. Moreover, the inflammatory markers (NF-κB, TNF-α, and IL-1β) were significantly elevated upon MTX treatment. In addition, MTX showed an apoptotic response mediated by elevating the pro-apoptotic (Bax) and lowering the anti-apoptotic (Bcl-2) proteins. All of these changes were confirmed by the observed alterations in the histopathological examination of the hepatic and renal tissues. Lut exposure significantly reversed all the MTX-induced changes in the measured parameters suggesting its potential protective role against the MTX-induced toxicity. Finally, our findings concluded the antioxidative, anti-inflammatory and anti-apoptotic effects of Lut as a mechanism of its protective role against the MTX-induced hepato-renal toxicity in rats.

AbstractAccording to modern ethnobotanical records, the fruit of Hippophae rhamnoides is effective in the treatment of different allergic symptoms. In order to obtain pharmacological evidence for this observation, the fruit was investigated for anti-inflammatory activity using in vivo animal models. Aqueous and 70% MeOH extracts were tested in 48/80-induced rat paw edema assay after oral administration, and it was found that the 70% MeOH extract (500 mg/kg) reduced significantly edema volume (0.660 ± 0.082 mL vs. control 0.935 ± 0.041 mL). Extracts of different parts of the fruit (pulp, peel, seed) were investigated in the same assay, and the peel extract was shown to exhibit maximum edema-reducing effect (0.470 ± 0.124 mL vs. control 0.920 ± 0.111 mL). This extract was used to elucidate the mode of action. Different inflammation inducers (serotonin, histamine, dextran, bradykinin, and carrageenan) were applied in the rat paw model, but the extract inhibited only the compound 48/80 elicited inflammation. The active extract was then fractionated by solvent-solvent partitioning and chromatographic methods with the guidance of the 48/80-induced anti-inflammatory assay, and the main compounds responsible for the activity were identified as ursolic acid and oleanolic acid. Our data suggest that the activity is most probably based on a membrane stabilizing effect caused by the inhibition of degranulation of mast cells. Moreover, previously unknown 2,5-bis-aryl-3,4-dimethyltetrahydrofuran lignans, nectandrin B, fragransin A2, and saucernetindiol were isolated and identified from H. rhamnoides for the first time.

Anti Inflammatory

Ischemia induces excessive ATP catabolism with subsequent local release of its metabolite adenosine, an autacoid with anti-inflammatory properties. Because activation of the vascular endothelium is critical to the inflammatory host response during ischemia and reperfusion, the effects of adenosine on two major determinants of endothelial cell activation (i.e., the release of proinflammatory cytokines and the expression of adhesion molecules) were studied. Adenosine dose dependently inhibited the release of interleukin (IL)-6 and IL-8 by stimulated human umbilical vein endothelial cells (HUVEC). Expression of E-selectin and vascular cell adhesion molecule 1 (VCAM-1), but not intercellular adhesion molecule 1 (ICAM-1), by activated HUVEC was also reduced by adenosine. Inhibition of endogenous adenosine deaminase activity by erythro-9-(2-hydroxy-3-nonyl)adenine or 2'-deoxycoformycin strongly enhanced the inhibitory effects of exogenous adenosine on cytokine release and expression of E-selectin and VCAM-1. However, a clear role for specific adenosine receptors in the described inhibitory events could not be established. Together, these data imply that the vascular endothelium constitutes an important target for the anti-inflammatory actions of adenosine.
