Overall Qualitative and Overall Quantitative Assessment of Compound Liquoric Tablets Using HPLC Fingerprints

The quality assessment of compound liquorice tablets by capillary electrophoresis fingerprints.

Capillary electrophoresis (CE) is a powerful separation technique that is peculiarly able to determine the fingerprints of traditional Chinese medicine. The Capillary Electrophoresis Fingerprints (CEFP) of compound liquorice tablets (CLTs) was established to evaluate the quality of CLTs. The background electrolyte was a 50 mM sodium borate solution. The detection wavelength was 228 nm and a 14 ...

Quantitative and qualitative determination of Liuwei Dihuang tablets by HPLC-UV-MS-MS.

A method is developed for the analysis of allantoin, gallic acid, dihydromelittoside, loganin, paeoniflorin, benzoylpaeoniflorin, and paeonol in Liuwei Dihuang tablets by high-performance liquid chromatography (HPLC)-UV-mass spectrometry (MS)-MS. Gradient elution with methanol-acetonitrile-water-formic acid solvent system is employed in the HPLC-electrospray ionization-MS study. The positive-io...

assessment of the efficiency of s.p.g.c refineries using network dea

data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...

Overall study on Iranian truffles

The Spring season in Iran, especially the months of April and May, is a thriving season for the wild harvesting and sale of fresh medicinal plants and mushrooms that are seen in the form of local markets and seasonal stores during the rainy season. Based on habitats of Iranian truffles, they can be classified in two groups including Desert truffles and Forest truffles. Based on our knowledge de...
