A new biflavonoid and an isobiflavonoid from Rhus tripartitum.
A new biflavonoid masazinoflavanone (1) and the isobiflavonoid calodenone (2) have been isolated and characterized from the methanolic aerial part extract of the plant Rhus tripartitum. Their structures have been deduced from extensive spectral analysis (NMR and MS). Interpretation of the nuclear overhauser effects (NOESY) permitted us to establish relative stereochemistry of these natural prod...
متن کاملHypolipidemic effect of a novel biflavonoid from shells of Camellia oleifera (Abel.).
Camellia oleifera Abel. [C. oleosa (Lour.) Rehd.], an evergreen plant, is used for healthful oil production, but the shells are always discarded and need to be utilized. The present study was undertaken to explore the effect of extracts from the shells of C. oleifera on adjusting cardiovascular system. A flavonoid was obtained by reflux extraction of the shells in 70% methanol, hydrolysis in 2 ...
متن کاملAnti-Inflammatory and Analgesic Activities of a Novel Biflavonoid from Shells of Camellia oleifera
Shells are by-products of oil production from Camellia oleifera which have not been harnessed effectively. The purpose of this research is to isolate flavonoid from shells of Camellia oleifera and evaluate its anti-inflammatory and analgesic effects. The flavonoid was identified as bimolecular kaempferol structure by UV, MS, 1H NMR and 13C NMR spectra, which is a new biflavonoid and first found...
متن کاملAnti-Neurodegenerative Biflavonoid Glycosides from Impatiens balsamina.
Four biflavonoid glycosides, balsamisides A-D (1-4), and nine known compounds (5-13) were obtained from the white petals of Impatiens balsamina. The 2D structures of the purified phytochemicals were established using conventional NMR techniques in addition to the new long-range HSQMBC NMR experiment. Acid hydrolysis followed by experimental and quantum-mechanics-based ECD data analysis permitte...
متن کاملPreussianone, a new flavanone-chromone biflavonoid from Garcinia preussii Engl.
A new flavanone-chromone biflavonoid, preussianone (1), has been isolated from the leaves of Garcinia preussii, along with four known biflavonoids. The absolute stereostructures were elucidated by chemical, spectroscopic, and chiroptical methods. The biological properties of the new biflavonoid against several bacterial strains were evaluated.
