Xueshuantong Lyophilized Powder (XST), consisting of a series of saponins extracted from Panax notoginseng, is widely applied to treat acute cerebral infarction, stroke, and coronary heart disease in China. However, most adverse drug reactions (ADR) in clinic are caused by quality problems of XST. In this study, six batches of certainly abnormal, four batches of possibly abnormal XST, and

Moringa ovalifolia is a rich source of pharmacologically relevant chlorogenic acids.. UPLC-qTOF-MS is a feasible technique for characterization of chlorogenic acid profile.. M. ovalifolia contains large amounts of cis-geometrical isomers of chlorogenic acids.

The ratio of DHA/EPA for MD products was 1.3–1.7 with one exception, while the fermented product (0.5), and crude samples (2.2–3.3) were different. The total concentration of EPA and DHA per 5 mL serving was 944–1200 mg in MD, Hepatocellular carcinoma (HCC) is a worldwide health problem.

Hepatocellular carcinoma (HCC) is a worldwide health problem. HCC patients show a 50% mortality within two years of diagnosis. To better understand the molecular pathogenesis at the level of lipid metabolism, untargeted UPLC MS—QTOF lipidomics data were acquired from resected human HCC tissues and their paired nontumor hepatic tissues (n = 46).

The main oligomers identified were cyclic as well as lineal from the first, second, and third series. Accurate Mass Structural Elucidation of Biomarkers in Yeastolate by UPLC/MS (qTof) and Composition Profiling by Multivariate Analysis to Reduce Variability in Cell Culture Media Barry Drew, Kim Schrag, and Chandana Sharma Cell Sciences and Development, SAFC/Sigma … 2019-11-26 A benchtop QTof mass spectrometer incorporating the XS Collision Cell for enhanced sensitivity and selectivity, resulting in the highest quality, most comprehensive qualitative information together with the ultimate in quantitative performance. The analyses were carried out by UPLC-MS-QTOF. The use of high resolution mass spectrometry allowed the structural elucidation of these compounds and their correct identification. The main oligomers identified were cyclic as well as lineal from the first, second, and third series.
