Epidendrum coryophorum belongs to the Orchidaceae family. Traditional uses of some species for this genus include infusions of the leaves used for kidney problems, treat influenza, conjunctivitis, liver pain, relieve kidney symptoms, and hypoglycemic effect. This work's objective was to determine the phytochemical profile of the ethanolic extract of Epidendrum coryophorum leaves and to evaluate the potential anti-inflammatory activity in vitro of the extract employing the erythrocyte membrane stabilization method. The phytochemical screening carried out in this work suggested phenols, coumarins, flavonoids, tannins, steroids, and sterols in the ethanolic extract of Epidendrum coryophorum leaves. Cardiotonic glycosides and carbohydrates were also found. The ethanolic extract's UV-Vis spectrum showed absorption maxima at 268 nm and 332 nm, which could correspond to flavonoids of the flavonoid classes, 3-OH substituted flavonols, or isoflavones. The quantitative determination of total phenols of the ethanolic extract was carried out using the Folin-Ciocalteu method. The total phenolic content expressed as mg Gallic acid equivalent (G.A.E.) per gram of extract was found to be 19,96 mgGAE/g of Epidendrum coryophorum. The ethanolic extract of Epidendrum coryophorum leaves showed hemolysis inhibition values ​​of 18,19% at 1,0 mg/mL, 38,98% at 1,5 mg/mL and 40,94% at 2,5 mg/mL compared with aspirin (positive control) giving values ​​of 65,33% at 1,0 mg/mL, 72,26% at 1,5 mg/mL and 73,75% at 2,5 mg/mL. The values ​​obtained for inhibition of hemolysis with ethanolic extract, compared with the values ​​obtained with a pure anti-inflammatory, are significant and demonstrate anti-inflammatory activity in Epidendrum coryophorum. Keywords: Epidendrum coryophorum, total phenolic content, microencapsulation, anti-inflammatory activity

In the last decades, it has been intensively studied natural alternatives to synthetic products. Chassalia kolly is one of the medicinal plants used traditionally for treatment of skin infections. This study aimed at identifying the diversity secondary metabolites, to investigate the antioxidant and anti-inflammatory activities of ethanolic extract of Chassalia kolly leaves. Total phenols were determined by Folin Ciocalteu method. The aluminum trichloride method has been used to quantify total flavonoids, while the determination of condensed tannins was carried out by the hydrochloric vanillin method. The antioxidant capacity was evaluated by 2, 2-diphenyl-l-picrylhydrazyl (DPPH), 2, 2'-Azino-bis- (3-ethylbenzothiazolin-6-sulfonic acid) (ABTS) and phosphomolybdenum methods. In vitro anti-inflammatory activity of ethanolic extract of Chassalia kolly leaves was evaluated by method membrane stabilization. In this results, Chassalia kolly leaves contain flavonoid, mucilages, anthocyans, sterols and terpenes, saponosides, alkaloids and reducing compounds. The contents of total phenols, total flavonoids and total tannins are respectively (20.41±2.11) µgGAE/mgDM; (30.29±2.18) µgQE/mgDM and (1.211±0.122)µgCE/mgDM. The results obtained during this work allowed us to assert that all extracts of the studied plant have very good antioxidant properties (IC50=0.05µg/µL). The ethanolic extract of the leaves of Chassalia kolly showed an anti-inflammatory activity more interesting than aspirin which is the reference compound used in this study.

Introduction: Neuroactive herbal drugs enriched with antioxidants are valuable in treating neurocognitive dysfunction and Vaccinium corymbosum, enriched with antioxidant phytochemicals, is used for treating memory disorders. Hence, the present study evaluated the neuroprotective effects of ethanolic extract of Vaccinium corymbosum (EEVC) on aluminium chloride(AlCl3)-induced Alzheimer’s type of dementia and haloperidol-induced catalepsy-associated behavioural changes. Methods:In vitro antioxidant potential was evaluated using 1-diphenyl-2-picrylhydrazyl (DPPH) and 2,2′-azino-bis (3-ethylbenzothiazoline-6-sulphonic acid) (ABTS). The total phenolic content (TPC) was quantified. For in vivo studies, AlCl3 (100 mg/kg) was orally administered for 42 days, whereas the EEVC was administered on the 21st day until the 42nd day in two doses (200 mg/kg and 400 mg/kg). In the haloperidol-induced group, EEVC was treated for 21 days, and haloperidol (1 mg/kg) was administered to induce behavioural changes. Open-field, Y-Maze and traction tests were performed, and the mice brain acetylcholinesterase (AChE) enzyme was determined. Results: IC50 values in DPPH and ABTS assays were 85.5 μg/mL and 80 μg/mL, respectively and the total phenolic content of EEVC was found to be 0.166 mg. In a behavioral study, animals treated with 200 mg/kg and 400 mg/kg of EEVC exhibited a neuroprotective impact on AlCl3-induced neurodegeneration and haloperidol-induced behavioral changes with significant inhibition (P < 0.05 and P < 0.01, respectively) in acetylcholinesterase enzyme. Conclusion: The neuroprotection by EEVC postulated that it is a promising therapeutic agent for treating behavioral and cognitive dysfunctions. Further investigations on pro-inflammatory cytokine and neuroendocrine regulation in transgenic Alzheimer’s disease (AD)models complement the therapeutic value of V. corymbosum.

The present study was conducted to evaluate the quality and bio-functional properties of Portuguese honeys of different botanical and geographical origins. Quality parameter analyses included the determination of palynological (predominant, secondary, minor and isolated pollen percentage), physicochemical (°Brix, moisture content, pH, electrical conductivity, free acidity, total dissolved solids, salinity, vitamin C content and specific weight) including colour-metrics (CIELAB, Pfund and colour intensity determinations), along with volatile compounds identification using solid phase micro-extraction coupled to gas chromatography mass spectrometry. Bio-activity parameter analysis included the determination of in vitro antioxidant activity and total phenolic content using the 2,2-diphenyl-1-picryl-hydrazyl and Folin-Ciocalteu assays, respectively. Melissopalynological analysis showed that Portuguese honeys were classified as eucalyptus, chestnut and heather, recording significant variations (p < 0.05) among physicochemical, volatile and bio-activity parameter analyses according to both: botanical and geographical origin. Based on the multi-parameter analysis data Portuguese honeys could be characterized by a distinctive colour, a characteristic aroma, whereas conform to the European legislation relating to honey identity and quality. Specific attention should be given in the case of heather honey which showed the highest in vitro antioxidant activity and total phenolic content. Parameters that were also highly correlated using bivariate statistics.

Fruit juices are considered as an important source of phenolic compounds. Black mulberry, pomegranate and orange juices were selected to assess their anti-inflammatory activity. Total phenolic content was determined using Folin-Ciocalteu colorimetric method. The anti-inflammatory activity was evaluated using RBC membrane stabilization method. Ibuprofen was used as a standard drug. Total phenolic content of black mulberry juice, pomegranate juice and orange juice was 3.02 gGAE/l, 1.83 gGAE/l and 0.76 gGAE/l and the percentage inhibition of RBC haemolysis varied between (27.41-43.19%), (24.06-39.06%) and (10.12-22.54%), respectively. Black mulberry juice revealed the highest anti-inflammatory activity among the studied juices. This finding might be attributed to the high phenolic content of this juice compared to others.
