Stachys lavandulifolia Vahl is an herbaceous wild plant native to Iran which is traditionally used in Iranian folk medicine as a mild sedative tea for reducing anxiety and for treatment of gastrointestinal disorders. Our previous study on ethyl acetate extract of S. lavandulifolia proved anti-anxiolytic activity and so the present study was designed to determine chemical components of this biol...

Bamboo shoots of Dendrocalamus asper is very important for human health because its high content dietary fiber, low sugar, negligible amount fat, rich in vitamins and minerals. In search new potential antimalarial agents, the chemical constituents bamboo were evaluated againts P. falciparum strain 3D7. One metabolite, (11E,13E,17E,19E)-dimethyl-15,16-dibutoxytriconta-11,13,17,19-tetraenedioate ...

Castilleja tenuiflora (Orobanchaceae) has been used in Mexican traditional medicine as a treatment for cough, dysentery, anxiety, nausea and vomiting as well as hepatic and gastrointestinal diseases. The ethanolic extract of the aerial parts of Castilleja tenuiflora was separated by silica gel column chromatography. The fractions were evaluated using the induced edema acetate 12-O-tetradecanoyl...

Pseudoshikonin I, the new bioactive constituent of Lithospermi radix, was isolated from this methanol extract by employing reverse-phase medium-pressure liquid chromatography (MPLC) using acetonitrile/water solvent system as eluents. The chemical structure was determined based on spectroscopic techniques, including 1D NMR (¹H, (13)C, DEPT), 2D NMR (gCOSY, gHMBC, gHMQC), and QTOF/MS data. In thi...

Rape pollen has always been considered as a research hotspot in health foods and pharmaceuticals due to its abundance of natural active ingredients. In this work, compound with antioxidant activity was directly isolated from the methanol extract rape using two-step procedure, under supervision online HPLC−1,1-diphenyl-2-picrylhydrazyl (HPLC-DPPH) detection. Firstly, HPLC−DPPH detection used ide...

Purpose: To isolate and identify chemical constituents with yeast α-glucosidase inhibitory activity from the methanol extract of V. myrtillus (blueberry) flowers. Methods: The active fraction (ethyl acetate extract) were chromatographed on C18 MPLC column, Sephadex LH-20 column and semi-preparative HPLC column. The isolated compounds were identified by the extensive H-nuclear magnetic resonance...

Combretum mucronatum Schumach. & Thonn. is a medicinal plant widely used in West African traditional medicine for wound healing and the treatment of helminth infections. The present study aimed at a phytochemical characterization of a hydroalcoholic leaf extract of this plant and the identification of the anthelmintic compounds by bioassay-guided fractionation. An EtOH-H2O (1:1) extract...

Tryptase is a tetrameric serine protease [l] which is present almost exclusively in the secretory granules of mast cells [2]. There has been some controversy over the extent to which tryptase may contribute to the generation of kinins which has been reported following mast cell activation [3,4]. Earlier studies suggested that tryptase does not generate bradykinin from either low molecular weigh...

The aim of this study was to isolate and identify secondary metabolites from Sonchus brachyotus evaluate their antioxidant anti-inflammatory activities. In study, we isolated three flavonoids a 70% EtOH extract by Medium Pressure Liquid Chromatography (MPLC) prep-High-Performance (HPLC). To the biological activities (an-tioxidant anti-inflammatory) these flavonoids, in vitro inhibitory against ...
