To develop an HPLC method for the simultaneous quantitation of five constituents in Scrophularia ningpoensis.Samples were analyzed on an Agilent SB-C18 column(4.6 mm x 250 mm, 5 microm) eluted with acetonitrile and water containing 0.03% phosphate acid as mob...

Effect of nanoconfinement on polymer dynamics: surface layers and interphases.

PLoS ONE 9(7) , e103118, (2014)

We present neutron spin echo experiments that address the much debated topic of dynamic phenomena in polymer melts that are induced by interacting with a confining surface. We find an anchored surface layer that internally is highly mobile and not glassy as h...

Effects of β-glucosidase hydrolyzed products of harpagide and harpagoside on cyclooxygenase-2 (COX-2) in vitro.

Bioorg. Med. Chem. 19 , 4882-6, (2011)

Harpagide (1) and harpagoside (2) are two iridoid glycosides existing in many medicinal plants. Although they are believed to be the main bioactive compounds related to the anti-inflammatory efficacy of these plants, the mechanisms of their anti-inflammatory ...

Preparative isolation and purification of harpagoside from Scrophularia ningpoensis hemsley by high-speed counter-current chromatography.

Phytochem. Anal. 17(6) , 406-8, (2006)

The bioactive component harpagoside was successfully separated from the crude extract of Scrophularia ningpoensis Hemsley by one-step purification using high-speed counter-current chromatography (HSCCC). A two-phase solvent system containing n-butanol:ethyl a...

Antiinflammatory activities of Hungarian Stachys species and their iridoids.

Phytother Res. 26(4) , 505-9, (2012)

The antiinflammatory activities of aqueous extracts prepared from the aerial parts of ten Hungarian Stachys species were investigated in vivo in the carrageenan-induced paw oedema test after intraperitoneal and oral administration to rats. Some of the extract...

Optimization of solid-phase extraction for the liquid chromatography-mass spectrometry analysis of harpagoside, 8-para-coumaroyl harpagide, and harpagide in equine plasma and urine.

J. Chromatogr. Sci. 46(2) , 174-83, (2008)

Solid-phase extraction cartridges among those usually used for screening in horse doping analyses are tested to optimize the extraction of harpagoside (HS), harpagide (HG), and 8-para-coumaroyl harpagide (8PCHG) from plasma and urine. Extracts are analyzed by...
