Isolation of Urosilic Acid from Knoxia corymbosa

Air-dried, milled leaves of Knoxia corymbosa (220 gm) were extracted repeatedly with dichloromethane. After removal of solvent in vacuo, the CH2Cl2-solvent residue was fractionated by using hexane and ethyl acetate solvents. After fractionation, all fractions are submitted for NMR spectroscopy. Out of all fractions interesting fractions are subjected to column chromatography, so that we isolate...

α-Glucosidase Inhibitors from Vauquelinia corymbosa.

The α-glucosidase inhibitory activity of an aqueous extract and compounds from the aerial parts of V. corymbosa was demonstrated with yeast and rat small intestinal α-glucosidases. The aqueous extract inhibited yeast α-glucosidase with a half maximal inhibitory concentration (IC50) of 28.6 μg/mL. Bioassay-guided fractionation of the extract led to the isolation of several compounds, including o...

Isolation of two isochlorogenic acid isomers from phenolic rich fraction of Artemisia turanica Krasch.

Total phenolic content (TPC) and antioxidant capacity of five different extracts (petroleum ether (40-60), dichloromethane, ethyl acetate, ethanol and ethanol-water (1:1 v/v)) of Artemisia turanica (A. turanica) aerial parts were determined and phytochemical study on the most promising extract was carried out. Folin–Ciocalteu method, 2, 2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging test...

Isolation of deoxyribonucleic acid from mammalian tissues.

1. DNA has been isolated from different mammalian tissues. The DNA preparations were free from RNA, protein and polysaccharides and have a similar range of sedimentation coefficients (approx. 24s). 2. Protein was removed by a two-stage extraction with a phenol-cresol mixture by using a detergent with 4-aminosalicylate in the first stage and sodium chloride in the second. 3. Polysaccharides rema...
