Abstract
Stephania venosa Spreng. (Menispermaceae) has yielded the first two 4,5,6,6a-tetradehydro-N-methyl-7-oxoaporphinium salts known, namely uthongine (4) and thailandine (5), which are partially decomposed by chromatography on silica gel to 7-oxocrebanine (6) and 7-oxostephanine (7), respectively.Keywords
