This study evaluated the nutritional and medicinal properties of seeds from Adansonia digitata (BSF) and Balanite aegyptiaca (DDSF) plant. Proximate chemical composition, mineral elements composition, flavonoids, phenolics, antioxidant capacity, and anti-inflammatory properties were studied. Results obtained revealed that DDSF had the highest moisture, crude fat and crude protein content of 7.66 %, 42.80 %, 20.37 % respectively, whilst BSF gave the highest ash, crude fibre and carbohydrate content. Elemental analysis revealed BSF had the highest Mg content (313.65 mg/100g) and DDSF gave the highest Ca content (118.62 mg/100g). Additionally, DDSF gave the highest total phenolics (18.89 mg TAE/ 100 g), total flavonoids (8.80 mg QE/ 100 g) as well as the highest total antioxidant capacity of (19.62 mg AAE/ 100 g) dry of extract. Based on results obtained in this study, seeds obtained from the Adansonia digitata and Balanite aegyptiaca could be a potential source of functional food and antioxidant agents.

<p class="Default"><strong>Objective</strong>:<strong> </strong>This report is an attempt to study the phenolic composition of <em>Rubus fruticosus </em>(RFE) and<em> Zizyphus vulgaris (</em>ZVE<em>) </em>methanol<em> </em>extracts<em> and </em>evaluate their antioxidant and anti-inflammatory effects <em>in-vitro</em> and <em>in-vivo</em>.</p><p><strong>Methods: </strong>Total phenolic and total flavonoids contents of extracts were determined by spectrophotometric methods. Phenolic compounds were identified by<strong> </strong>HPLC-TOF/MS. The antioxidant activities were evaluated <em>in vitro</em> using DPPH, ABTS and FRAP assays. The effect of RFE and ZVE<em> </em>on DNA cleavage induced by H<sub>2</sub>O<sub>2</sub> UV-photolysis was also investigated. The antioxidant effect of RFE and ZVE was tested <em>in vivo</em> using the blood total antioxidant capacity test in mice. On the other hand, the anti-inflammatory activity was assessed <em>in vivo</em> using two models of acute inflammation ear edema and vascular permeability.</p><p><strong>Results: </strong>The phytochemical analysis of these extracts showed that RFE possesses higher polyphenolic and flavonoid content than ZVE. in the same way RFE exerted the highest antioxidant capacity with IC<sub> 50 </sub>value of 14 µg/ml in DPPH assay, 1.58 mmol of Trolox E/mg extract and 3.39 of mmol FesO<sub>4</sub>/mg extract in ABTS, and FRAP assay respectively. The studied extracts showed a concentration-dependent protective effect on DNA cleavage induced by H<sub>2</sub>O<sub>2</sub> UV-photolysis. The daily oral administration of 200 mg/kg of RFE or ZVE during three weeks showed an improvement of the blood total antioxidant capacity; the HT<sub>50</sub> values were151.45 min and 146.72 min for the groups treated with RFE and ZVE, respectively <em>versus</em> 122.5 min for the control group. The topical application of 2 mg/ear of RFE inhibited the croton oil-induced ear edema by 75.72%, while the inhibition exerted by ZVE was 64.24%. These inhibitions were higher than that of indomethacin, used as a reference. Moreover, the oral administration of 400 mg/kg of RFE inhibited significantly (33.57%) acetic acid induced vascular permeability in mice. However, this effect was lower than this of indomethacin. The inhibition effect exerted by ZVE was not significant.</p><p><strong>Conclusion</strong><strong>:</strong><strong> </strong>The results obtained in this investigation showed that RFE possesses strong antioxidant and anti-inflammatory potential in comparison with ZVE, which may be attributed to the presence of polyphenolic phytoconstituents.</p>

This research aimed to evaluate the in vitro effect of buffer extract obtained from leaves and pseudobulbs (modified shoots) of Dendrobium parishii Rchb. f. on the 2-thiobarbituric acid reactive substances (TBARS) as lipid peroxidation biomarker, aldehydic and ketonic derivatives of oxidatively modified proteins, and total antioxidant capacity (TAC) in the muscle tissue of the rainbow trout (Oncorhynchus mykiss Walbaum). The shoots (pseudobulbs) with leaves of Dendrobium parishii cultivated under glasshouse conditions were sampled at M.M. Gryshko National Botanic Garden (NBG) (Kyiv, Ukraine). Since 1999, the whole collection of tropical and subtropical plants (including orchids) has had the status of a National Heritage Collection of Ukraine and is supported through State funding. Besides, NBG’s collection of tropical orchids was registered at the Administrative Organ of CITES in Ukraine (Ministry of Environment Protection, registration No. 6939/19/1-10 of 23 June 2004). The collected pseudobulbs and leaves were brought into the laboratory for biochemical studies. Freshly collected leaves were washed, weighed, crushed, and homogenized in 0.1M phosphate buffer (pH 7.4) (in proportion 1:19, w/w) at room temperature. The extract was then filtered and investigated for its antioxidant capacity. The extract was stored at -20°C until use. The increase in TBARS level in the muscle tissue exposed to extracts derived from leaves and pseudobulbs of D. parishii was insignificant. The level of ketonic derivatives of oxidatively modified proteins was non-significantly decreased both for leaf and pseudobulb extracts compared to the untreated samples. The extracts obtained from leaves and pseudobulbs of D. parishii significantly increased the TAC level in muscle tissue due to inhibited the Fe2+/ascorbate-induced oxidation of Tween 80. Overall, these findings demonstrate that aqueous extracts of vegetative organs of Dendrobium parishii can enhance the total antioxidant capacity in the muscle tissue of the rainbow trout. Moreover, this antioxidant effect was more intensive for pseudobulb extracts.

We examinedin vitroantioxidant capacity of polyphenolic extract obtained from the wood of oakQuercus robur(QR), Robuvit, using TEAC (Trolox equivalent antioxidant capacity) method and the effect of its intake on markers of oxidative stress, activity of antioxidant enzymes, and total antioxidant capacity in plasma of 20 healthy volunteers. Markers of oxidative damage to proteins, DNA, and lipids and activities of Cu/Zn-superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx) were determined in the erythrocytes. We have found anin vitroantioxidant capacity of Robuvit of 6.37 micromole Trolox equivalent/mg of Robuvit. One month intake of Robuvit in daily dose of 300 mg has significantly decreased the serum level of advanced oxidation protein products (AOPP) and lipid peroxides (LP). Significantly increased activities of SOD and CAT as well as total antioxidant capacity of plasma after one month intake of Robuvit have been shown. In conclusion, we have demonstrated for the first time that the intake of Robuvit is associated with decrease of markers of oxidative stress and increase of activity of antioxidant enzymes and total antioxidant capacity of plasmain vivo.

 Objective: The objective of the present work is to study the in vitro anti-inflammatory and antioxidant activity of medicinal plants. The extent and correlation between anti-inflammatory and antioxidant activity have been studied.Method: Methanolic and aqueous extracts of five medicinal plants, namely, Ficus racemosa, Aloe vera, Cannabis sativa, Datura stramonium, and Calotropis gigantean have been taken for in vitro anti-inflammatory and total antioxidant activity.Result: The study showed that the inhibition of protein (albumin) denaturation was maximum in aqueous extract of A. vera with 97.55±1.45%. Proteinase inhibitory action of different plant extracts showed significant action and was found to be maximum in aqueous extract of D. stramonium with 87.89±2.58%. Heat-induced hemolysis showed that maximum inhibition was with aqueous extract of F. racemosa with 90.72±3.33%. When hypotonicity-induced hemolysis activity was done it was found maximum in methanolic extract of C. gigantea with 90.58±3.04%. Anti-lipoxygenase activity was found maximum in methanolic extract of F. racemosa with 94.05±4.24%. When total antioxidant activity was done, it was found highest in F. racemosa (4.38±0.546 mM equivalent of ascorbic acid/g tissue).Conclusion: An overall strong positive correlation between anti-inflammatory and antioxidant activity was observed, indicating that antioxidant activity of the plant species studied might be responsible for their anti-inflammatory property. Further work needs to be undertaken to fully elucidate the antioxidants responsible for anti-inflammatory action and to develop better herbal drug formulations.

The methanol extract of the leaves of Buddleja asiatica Lour. (Loganiaceae) showed antioxidant activity toward the well known in vitro antioxidant tests such as total antioxidant capacity by the phosphomolybdenum method, free radical scavenging activity by the 1,1- diphenyl-2-picrylhydrazyl scavenging assay (DPPH assay) and hydrogen peroxide scavenging methods. Due to the high scavenging activity of the n-butanol successive fraction toward DPPH and H2O2 (SC50 = 11.99 and 18.54 μg/ml, respectively), this extract was subjected to chromatographic separation and isolation. Four non-phenolic compounds were isolated and identified on the basis of spectroscopic and chemical analyses: 1-O-ß-D-glucopyranosyl- 2-methoxy-3-(2-hydroxy-triaconta-3,12-dienoate)-glycerol (1), 3-O-[α-l-rhamnopyranosyl- (1→4)-ß-d-glucopyranosyl-(1→3)]-[ß-d-glucopyranosyl-(1→2)]-ß-d-fucopyranosyl-olean- 11,13(18)-diene-3ß,23,28-triol (2), 3-O-[α-l-rhamnopyranosyl-(1→4)-ß-d-glucopyranosyl- (1→4)-ß-d-glucopyranosyl-(1→3)]-ß-d-fucopyranosyl-olean-11,13(18)-diene-3ß,23,28-triol (3), and 3-O-[α-l-rhamnopyranosyl-(1→4)-ß-d-glucopyranosyl-(1→3)]-[ß-d-xylopyranosyl- (1→2)]-ß-d-glucuronopyranosyl-acid-olean-11,13(18)-diene-3ß,23,28-triol (4). The four compounds were evaluated as antioxidant agents using the three antioxidant bioassay tests.

Background. Oxidative processes might increase in patients with end-stage renal disease (ESRD) according to the current literature. Oxidative stress (OS) is a risk factor of atherosclerosis and cardiovascular complications, which are major causes of mortality among ESRD patients. Haemodialysis (HD) is life-saving procedure, nevertheless it is an active chronic inflammatory status that could augment cardiovascular disease and increase mortality. Gum Arabic (GA) has been claimed to act as an antioxidant and anti-inflammatory agent in experimental studies and clinical trials. Therefore, we assumed GA supplementation among haemodialysis patients would reduce oxidative stress and consequently reduce the state of chronic inflammatory activation associated with haemodialysis. Methods. Forty end-stage renal failure (ESRF) patients aged 18–80 years who were on regular haemodialysis in Arif Renal Center, Omdurman, Sudan, were recruited. All recruited patients met the inclusion criteria and signed informed consent prior to enrolment. The patients received 30 g/day of GA for 12 weeks. C-reactive protein (CRP) and complete blood count (CBC) were measured as baseline and monthly. Total antioxidant capacity (TAC) and oxidative stress marker malondialdehyde (MDA) levels were measured before and after GA intake. Ethical approval from the National Medicines and Poisons Board was obtained. Results. Gum Arabic significantly augmented total antioxidant capacity level (P<0.001) (95% CI, 0.408–0.625) and also attenuated oxidative marker MDA and C-reactive protein (P<0.001). Conclusions. GA has revealed potent antioxidative and anti-inflammatory properties in haemodialysis patients. Oral digestion of GA (30 g/day) decreased oxidative stress and inflammatory markers among haemodialysis patients. Trial registration. ClinicalTrials.gov Identifier: NCT03214692, registered 11 July 2017 (prospective registration).

In this study, we determined the antimicrobial activity of ten essential oils (EOs)—oregano, thyme, clove, arborvitae, cassia, lemongrass, melaleuca, eucalyptus, lavender, and clary sage—against drug-resistant microorganisms previously isolated from patients with skin infections. The essential oil compositions were determined using gas chromatography coupled to mass spectrometry (GC/MS). The assayed bacteria included Pseudomonas aeruginosa, Proteus vulgaris, Citrobacter koseri, and Klebsiella pneumoniae. Two drug-resistant yeasts (Candida albicans and Candida parapsilosis) were also involved in our survey. Oregano, thyme, cassia, lemongrass and arborvitae showed very strong antibacterial and antifungal activity against all tested strains. These results show that these essential oils may be effective in preventing the growth of the drug-resistant microorganisms responsible for wound infections. In this study, the genotoxic effects of tested essential oils on healthy human keratinocytes HaCaT were evaluated using the comet assay for the first time. These results revealed that none of the essential oils induced significant DNA damage in vitro after 24 h. Moreover, the treatment of HaCaT cells with essential oils increased the total antioxidant status (TAS) level. The obtained results indicate that EOs could be used as a potential source of safe and potent natural antimicrobial and antioxidant agents in the pharmaceutical and food industries.
