Three new glycoalkaloids, N-formyl-asimilobine-2-O-β-D-glucoside (1), (-)-1-O-β-D-glucoside-8-oxotetrahydropalmatine (2), and 1-N-monomethylcarbamate-argentinine-3-O-β-D-glucoside (3) were isolated from tubers of Stephania succifera. The structures were established based on spectroscopic analysis,
Biological evaluation of extracts prepared from the tubers of Stephania pierrei revealed cytotoxic and antimalarial activity. During the course of separation, two new aporphine alkaloids, (-)-asimilobine-2-O-beta-D-glucoside [2] and (-)-nordicentrine [8], in addition to twenty-one known isoquinoline
A new aporphine glycoside (1), named 'angkorwatine', and eight known alkaloids: oblongine (2), stepharine (3), asimilobine-β-d-glucopyranoside (4), isocorydine (5), tetrahydropalmatine (THP) (6), jatrorrhizine (7), palmatine (PAL) (8), and roemerine (ROE) (9) were simultaneously isolated from the
