Isolation of Antiosteoporotic Compounds from Seeds of Sophora japonica
Chemical investigation of Sophora japonica seeds resulted in the isolation of seven metabolites identified as: genistin (1), sophoricoside (2), sophorabioside (3), sophoraflavonoloside (4), genistein 7,4'-di-O-β-D-glucopyransoide (5), kaempferol 3-O-α-L-rhamnopyranosyl(1 → 6)β-D-glucopyranosyl(1 → 2)β-D-glucopyranoside (6) and rutin (7). Compounds 1, 2 and 5 showed significant estrogenic prolif...
متن کاملIsolation of antibacterial diterpenoids from Cryptomeria japonica bark.
The aims of the present study were to determine the antibacterial activity of bark extract of Cryptomeria japonica D. Don and to isolate potential antibacterial constituents. The results showed that the ethanolic extract of C. japonica bark possessed a good antibacterial activity. Nine compounds including seven diterpenoids (ferruginol (I), isopimaric acid (II), iguestol (III), isopimarol (IV),...
متن کاملIsolation of viable cell types from the gill epithelium of Japanese eel Anguilla japonica.
High-purity viable cells with low mitochondria (pavement cells) and mitochondria-rich content (chloride cells) were successfully isolated from the gill epithelium of Japanese eels, using three-step Percoll gradient low-speed centrifugation. Cytochemistry (silver staining for chloride, rhodamine-123, and Mitotracker for mitochondria and actin/spectrin immunofluorescence) and scanning electron mi...
متن کاملIsolation, structural elucidation, and cytotoxicity of three new ent-kaurane diterpenoids from Isodon japonica var. glaucocalyx.
Three new ENT-kaurane diterpenoids, glaucocalyxin H ( 1), glaucocalyxin I ( 2), and glaucocalyxin J ( 3), together with four known diterpenoids ( 4- 7), were isolated from the leaves of Isodon japonica Hara var. glaucocalyx. Their structures were elucidated by spectroscopic analysis, and the structures of compounds 2 and 3 were further confirmed by X-ray crystallographic analysis. Compounds 1, ...
متن کاملStilbenoids from Stemona japonica.
Three new dihydrostilbenes, stilbostemins J-L (1-3), and a new dihydrophenanthrene, stemanthrene F (4), were isolated from the roots of Stemona japonica together with two known bibenzyls, 3,5-dihydroxy-4-methylbibenzyl (5) and 3,5-dihydroxy-2'-methoxy-4-methylbibenzyl (6). Their structures were elucidated by spectroscopic analyses. Compounds 3-6 exhibited strong antibacterial activities against...
