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.
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.

[Simultaneous determination of five constituents in Scrophularia ningpoensis by HPLC].
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.
