Metabolomics Study of Flavonoids of on Different Hosts Using UPLC-ESI-MS/MS.

The goal of this study was to identify and compare the main biomarkers of from different hosts. A metabolomics approach utilizing ultra-pressure liquid chromatography coupled with tandem mass spectrometry (UPLC-MS), including cluster analysis, sample correlation analysis and orthogonal partial least squares discriminant analysis, was used to explore the flavonoid metabolites of growing on different hosts. Results: The total flavonoids content (up to 30.

Investigation of the Effects and Mechanisms of Rolfe Extract on the Treatment of Gout.

Objective: Gout is a chronic disease that causes inflammatory arthritis, which is closely related to urate accumulation induced by a disorder of uric acid metabolism and the consequent deposition of monosodium urate crystals. Rolfe is an herbal medicine that has been used in some traditional Chinese medicine formulae in the treatment of gout. This study aimed to explore and verify the antigout activity of extract (DLE) on alleviating the hyperuricaemia of mice and the acute gouty arthritis of rats.

[Relativity among starch quantity, polysaccharides content and total alkaloid content of Dendrobium loddigesii].

Objective: To find out the relativity among starch quantity, polysaccharides content and total alkaloid content of Dendrobium loddigesii.

Method: Microscopy-counting process was applied to starch quantity statistics, sulfuric acid-anthrone colorimetry was used to assay polysaccharides content and bromocresol green colorimetry was used to assay alkaloid content. Pearson product moment correlation analysis, Kendall's rank correlation analysis and Spearman's concordance coefficient analysis were applied to study their relativity.
