Two New Prenylated Flavonoids From Paracalyx Scariosa
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.

متن کاملA new prenylated indole diketopiperazine alkaloid from Eurotium cristatum.
A new prenylated indole diketopiperazine alkaloid, cristatumin F (1), and four known metabolites, echinulin (2), dehydroechinulin (3), neoechinulin A (4) and variecolorin O (5), were isolated from the crude extract of the fungus Eurotium cristatum. The structure of 1 was elucidated primarily by NMR and MS methods. The absolute configuration of 1 was assigned using Marfey's method applied to its...
متن کاملA new prenylated flavanone from Derris trifoliata Lour.
A new flavanone, 4',5,7-trihydroxy-6,8-di-(2-hydroxy-3-methylbut-3-enyl)- flavanone, was isolated from the aerial parts of Derris trifoliate, together with eleven known compounds: rotenone, tephrosin, 12a-hydroxyrotenone, deguelin, 6a,12a-dehydro-rotenone, dehydrodeguelin, 7a-O-methyldeguelol, 7a-O-methylelliptonol, 5,7,3',4'-tetra-hydroxy-6,8-diprenylisoflavone, daidzein and 4'-hydroxy-7-metho...
