Influence of processing procedure on the quality of Radix Scrophulariae: a quantitative evaluation of the main compounds obtained by accelerated solvent extraction and high-performance liquid chromatography.
    Journal of separation science, 2015, Volume: 38, Issue:3

    An improved high-performance liquid chromatography with diode array detection combined with accelerated solvent extraction method was used to simultaneously determine six compounds in crude and processed Radix Scrophulariae samples. Accelerated solvent extraction parameters such as extraction solvent, temperature, number of cycles, and analysis procedure were systematically optimized. The results indicated that compared with crude Radix Scrophulariae samples, the processed samples had lower contents of harpagide and harpagoside but higher contents of catalpol, acteoside, angoroside C, and cinnamic acid. The established method was sufficiently rapid and reliable for the global quality evaluation of crude and processed herbal medicines.

    Zhongguo Zhong yao za zhi = Zhongguo zhongyao zazhi = China journal of Chinese materia medica, 2011, Volume: 36, Issue:6

    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 mobile phases in a linear gradient mode. The flow rate was kept at 1.0 mL x min(-1), and the column temperature was set to 30 degrees C. The DAD detector wavelengths were 210, 280, 330 nm.. The linear ranges were 50-400 mg x L(-1) for harpagide, 1-40 mg x L(-1) for harpagoside, 1-20 mg x L(-1) for cinnamic acid, 0.5-4.5 mg x L(-1) for acteoside,1-60 mg x L(-1) for angoroside C, respectively. The average recoveries of the five constituents were 100.8% (RSD 0.62%), 101.7% (RSD 0.32%), 98.8% (RSD 0.48%), 99.9% (RSD 1.4%), 99.2% (RSD 1.1%), respectively.. Through the validation, the method was proved to be sensitive, accurate, repeatable, and can be used for quality control of the roots of S. ningpoensis.

Fast repairing of oxidized OH radical adducts of dAMP and dGMP by phenylpropanoid glycosides from Scrophularia ningpoensis Hemsl.
    Acta pharmacologica Sinica, 2000, Volume: 21, Issue:12

    To investigate the antioxidative activity of the constituents of the roots of Scrophularia ningpoensis (Chinese name: Xuanshen).. The main compounds from the roots of Scrophularia ningpoensis were isolated and identified by chromatography and FABMS, NMR etc. Using the techniques of pulse radiolysis, the electron transfers from iridoid glycosides (IG) or phenylpropanoid glycosides (PG) to oxidized OH radical adducts of 2'-deoxyadenosine-5'-monophosphate acid (dAMP) or 2'-deoxyguanosine-5'-monophosphate acid (dGMP) were observed.. Two IG: harpagoside and harpagide, two PG: angoroside C and acteoside were obtained as the main hydrophilic constituents of the plant. At 0.1 mmol/L concentration, angoroside C and acteoside were able to repair the oxidized OH adducts dAMP and dGMP significantly. However, harpagoside and harpagide had no such effect. The electron transfer rate constants of angoroside C with dAMP and dGMP were 4.2 x 10(8) and 10.3 x 10(8) L.mol-1.s-1; the electron transfer rate constants of acteoside with dAMP and dGMP were 5.3 x 10(8) and 20.2 x 10(8) L.mol-1.s-1.. PG from Scrophularia ningpoensis have a potent antioxidative activity for reducing of the oxidized OH adducts of dAMP and dGMP.
