Five 2-(2-Phenylethyl)chromones from Sodium Chloride-Elicited Aquilaria sinensis Cell Suspension Cultures.
Five 2-(2-phenylethyl)chromones including a new one, (5S,6R,7S,8R)-5,8-dichloro-6,7-dihydroxy-2-phenylethyl-5,6,7,8-tetrahydro-4H-chromen-4-one (1), and four known ones (2-5), were isolated from 150 mM NaCl-elicited Aquilaria sinensis cell suspension cultures. In addition, three feruloyl amides (6-8), six nucleosides (9-14), (+)-syringaresinol (15), indole-3-carboxaldehyde (16), and two glycosi...
متن کاملScreening and isolation of natural antioxidants from Acer ginnala Max. by TLC-MS/MS guided bioautographic method
A rapid and simple method has been developed for the screening and identification of natural antioxidants from the leaves of Acer ginnala Maxim.( AG). The process is that upon reaction with 1,1-diphenyl-2-picrylhydrazyl (DPPH), the white yellow spots of compounds with potential antioxidant effects will be significantly observed on the thin-layer chromatography (TLC), and possible structures wil...

متن کاملSimultaneous determination of ferulic acid and phthalides of Angelica sinensis based on UPLC-Q-TOF/MS.
The radix of Angelica sinensis (AS) is one of the most commonly used as a herbal medicine. To investigate the geoherbalism and quality evaluation of AS, an ultra performance liquid chromatography coupled with electrospray ionization quadrupole time-of-flight tandem mass spectrometry (UPLC-ESI-Q-TOF/MS) method was established to analyze and identify ferulic acid and phthalides in AS. The results...
متن کاملNew Flavones, a 2-(2-Phenylethyl)-4H-chromen-4-one Derivative, and Anti-Inflammatory Constituents from the Stem Barks of Aquilaria sinensis.
In the current study, two new flavones, 4'-O-geranyltricin (1) and 3'-O-geranylpolloin (2), and a new 2-(2-phenylethyl)-4H-chromen-4-one derivative, 7-hydroxyl-6-methoxy-2-(2-phenylethyl)chromone (3), have been isolated from the stem barks of A. sinensis, together with 21 known compounds 4-24. The structures of new compounds 1-3 were determined through spectroscopic and MS analyses. Compounds 2...
