two new prenylated flavonoids from paracalyx scariosa
Authors
abstract
two new prenylated flavonoids, named scariosin (1) and isorhynchospermin (2) were isolated from the leaves of paracalyx scariosa together with kaempferol, quercetin, kaempferol 3-o- rutinoside and rutin. the structures of (1) and (2) were characterized as 8-c- prenyl- taxifolin 7,3'-dimethylether and 6-c-prenylquercetin 7,4'-dimethylether by their chemical and spectra data, respectively.

full textPrenylated Flavonoids from Pongamia pinnata
Pongamia pinnata (Leguminosae) is widely distributed along southeastern Asia to the west Pacific and north Australia. All parts of the plant have been used as crude drug for the treatment of tumors, piles, skin diseases, wounds, ulcers, etc. [1]. Extracts of the plant possess significant anti-diarrhoeal, anti-fungal, anti-plasmodial, anti-ulcerogenic, anti-inflammatory, analgesic activities [2 ...
full textTyrosinase inhibitory prenylated flavonoids from Sophora flavescens.
For the purpose of the development of a skin-whitening agent, Sophora flavescens was evaluated for tyrosinase inhibitory activity and its active principles were identified following activity-guided isolation. The ethanol extract and dichloromethane fraction from S. flavescens showed significant inhibition of mushroom tyrosinase. From the dichloromethane fraction, three known prenylated flavonoi...
full textRare prenylated flavonoids from Tephrosia purpurea.
Chemical investigations of aerial parts of Tephrosia purpurea yielded the rare prenylated flavonoids, tephropurpulin A (1) and isoglabratephrin (2), in addition to a previously identified flavonoid, glabratephrin (3). Structures were established by 1D and 2D NMR spectroscopy, as well as by HR-MS analysis; for compounds 2 and 3, structures were confirmed by X-ray analysis.
full textIsolation and Biological Evaluation of Prenylated Flavonoids from Maclura pomifera
Phytochemical analysis of the ethanolic extract of Maclura pomifera fruits yielded four new compounds (I-IV) along with eleven known compounds (V-XV). The crude extract exhibited significant activity towards cannabinoid receptors (CB1: 103.4% displacement; CB2: 68.8% displacement) and possibly allosteric interaction with δ and μ opioid receptors (-49.7 and -53.8% displacement, resp.). Compound ...
full textTwo new flavonoids from Andrographis rothii.
Two new flavonoids, 5, 7, 2', 5'-tetramethoxyflavanone (1) and 5-hydroxy-7, 2'-dimethoxyflavone (2), together with two known flavones, skullcapflavone I (3) and echioidin (4) were isolated from the whole plant of Andrographis rothii. The structures of the new compounds were established by extensive one- and two-dimensional (1D- and 2D-) NMR spectral studies.
