Protoberberine isoquinoline alkaloids from Arcangelisia gusanlung.

HPLC-DAD-directed isolation and purification of the methanol extract of stems of Arcangelisia gusanlung H. S. Lo. led to the isolation of a new protoberberine alkaloid, gusanlung E (1), along with fourteen known derivatives 2-15, seven of which were obtained from the genus Arcangelisia for the first time. The structures and absolute stereochemistry of these compounds were elucidated on the basi...

Quaternary isoquinoline alkaloids from Stephania cepharantha.

From the quaternary alkaloidal fraction of the dried tubers of Stephania cepharantha, two new isoquinoline alkaloids, stecepharine and tetradehydroreticuline have been isolated along with the known compounds, magnoflorine, menisperine, steponine, cyclanoline, oblongine, cis-N-methylcapaurine and 2'-N-methylisotetrandrine. cis-N-Methylcapaurine (=9-O-methylstecepharine) was isolated as a natural...

Surface-enhanced Raman scattering of protoberberine alkaloids

Quaternary protoberberine alkaloids are a class of natural dyes characterized by bright colors ranging from yellow to orange. As they present a strong fluorescence emission, their analysis by Raman spectroscopy is limited to specific techniques such as Fourier transform (FT)-Raman and spectral shift Raman techniques such as shifted subtracted Raman difference spectroscopy (SSRDS) and shifted ex...

Antiplasmodial and antioxidant isoquinoline alkaloids from Dehaasia longipedicellata.

The crude extract of the bark of Dehaasia longipedicellata exhibited antiplasmodial activity against the growth of Plasmodium falciparum K1 isolate (resistant strain). Phytochemical studies of the extract led to the isolation of six alkaloids: two morphinandienones, (+)-sebiferine (1) and (-)-milonine (2); two aporphines, (-)-boldine (3) and (-)-norboldine (4); one benzlyisoquinoline, (-)-retic...
