The quality of drug is vital to its curative effect, thus it is important to develop a comprehensive quality control method for commonly used drugs. In this study, we developed a Gas chromatography-mass spectrometry separation method for the qualitative and quantitative analysis of volatiles,

The dried flower buds of Magnolia biondii Pamp are one of the most widely used medicinal plants officially listed in the Chinese Pharmacopoeia. A 2-D column-switching system without sample loop trapping, where two columns were switched directly via a six-port two-position switching valve, was

A new amide, magnolamide (1), and a new lignan, magnolone (2), whose structures were determined on the basis of spectral analysis, were found in the leaves of Magnolia coco. Eleven known compounds (episesamin, sesamin, magnolol, fargesin, aschantin, epieudesmin, syringaresinol,

Guided by PAF induced platelet aggregation, six active lignins were isolated from the flower buds of Magnolia biondii and identified as fargesin, demethoxyaschantin, aschantin, pinoresinol dimethyl ether, magnolin, lirioresinol-B dimethyl ether. The 13CNMR and CD data were reported and the

Mas-related G protein-coupled receptor X2 was a mast cell specific receptor mediating anaphylactoid reactions by activating mast cells degranulation, it was also identified as a target for modulating mast cell-mediated anaphylactoid and inflammatory diseases. The anti-anaphylactoid drugs used

Based on the inhibition of Cu(2+)-induced LDL oxidation as marker, the major antioxidants in the fruits of Forsythia suspensa and the stems of Magnolia coco were identified. Of these bioactive tetrahydrofurofuran lignans, pinoresinol, phillygenin, and syringaresinol were more potent than probucol.

In order to establish the antiallergic properties of Schisandra fructus and Magnolia flos, several compounds isolated from these plants were tested for 5-lipoxygenase (5-LOX) inhibitory activity in vitro, for the first time. The compounds including schizandrins, schisandrols, gomisins, fargesin,

Activated microglia produces diverse neurotoxic factors such as nitric oxide (NO) and tumor necrosis factor-alpha that serve as apoptotic inducers resulting in various neurodegenerative diseases. The inhibition of microglia-derived NO production by inducible nitric oxide synthase (iNOS) has been
