Purpose: To compare the flavonoid biomarker content (baicalin, baicalein and wogonin) of eleven commercial tinctures derived from Scutellaria lateriflora aerial parts (n=7) baicalensis root (n=4). S. are used in by western herbal practitioners to treat anxiety whereas inflammatory disease. Methods: Baicalin were purchased Aldrich Chemical Co. Wogonin was ChromaDex. The internal standard (4-hydroxybenzoic acid) obtained Acros Organics. column a Luna C18, 5 ?m (150 x 4.6 mm, Phenomenex)...
The methanolic crude extract from the roots of Jacquinia flammea showed moderate antifungal activity against dermatophytes and very strong Colletotrichum gloeosporioides. bioassay-guided purification extract, using a combination vacuum-liquid chromatography high performance liquid chromatography, allowed identification sakurasosaponin (1) as main metabolite responsible for activity.
To measure the rosmarinic acid content of eight commercial tinctures derived from fresh (n= 5) and dried (n=3) Melissa officinalis herb.Rosmarinic internal standard (esculin) were purchased Aldrich Chemical Co. The column used was a Luna C18, 5 um (150 x 4.6 mm I.D., Phenomenex) maintained at ambient room temperature. HPLC system consisted Shimadzu SCL-6B controller, LC-6A pumps, SPD-6A UV single wavelength spectrophotometric detector set to 320 nm SIL-6B autosampler. Gradient elution...
To evaluate the anti-inflammatory, analgesic, antioxidant and acute toxicity of extracts obtained from a successive extraction with solvents ascending polarity [hexane, hex; chloroform, CHCl3 ethanol (EtOH)] Ternstroemia sylvatica Schltdl. & Cham.The potential was evaluated by 2,2 diphenyl-1-picrylhydrazyl, ferric reducing/antioxidant power assays determining total phenolic content. The anti-inflammatory antinociceptive effects were using in vivo croton oil-induced ear edema, phorbol...
The crude ethanolic extract of leaves, stem-bark and roots J. flammea were tested for their cytotoxic effect against two mammalian cell lines (HeLa RAW 264.7) four bacterial species (Staphylococcus aureus, Bacillus subtilis, Escherichia coli Pseudomonas aeruginosa). When at the concentration 100 microg/mL, root showed highest activity cells followed by while leaves did not show significant activity. No antibacterial was detected all extracts when up to 500 microg/disc in disc diffusion...
Hyperammonemia is characterized by the excessive accumulation of ammonia in body as a result loss liver detoxification, leading to development hepatic encephalopathy (HE). These metabolic alterations carry cognitive and motor deficits cause neuronal damage, with no effective treatment at present. In this study, we aimed evaluate effect two subacute oral administrations flaxseed oil (0.26 0.52 mL/kg) on short- long-term memory, visuospatial locomotor activity, coordination, morphology...
Leaves of Croton stipulaceuswere extracted (EHex, ECHCl3and EEtOH extracts) to assesstheir antioxidant potential, anti-inflammatory activity in murine models and acute toxicity. showed the highest effect DPPH (37.80% inhibition), FRAP (1065.00 ± 55.30 μmolFe2+) total polyphenols (231.24 9.05 meq AG/gM). EHex was most active, ~ 50% inhibition TPA-induced ear edema; while (dose 2 mg/ear) chronic model (97% inhibited MPO (48%). In carrageenan-induced edema, ECHCl3(dose 500 mg/kg) active. None...
Piper is a large plant genus containing essential oils rich in mono and sesquiterpenes other secondary metabolites showing different biological activities. aequale, cordoncillo, used México for urinary prostate ailments, suggesting potential therapeutic effect against cancer. Due to the lack of chemical pharmacological information on this species, work antimicrobial antiproliferative activities were evaluated. Leaves ethanol methanol extracts assess antioxidant activity (DPPH, FRAP),...
