Stephania sasakii

The new proaporphine iso-oridine (1), isomeric with the known oridine (2), has been isolated from Papaver oreophilum.3 The supporting structural data include l3C n.m.r. spectroscopy. A-Acetylstepharine (3) has been found for the first time as a natural compound in Stephania sasakii.4... [Pg.135]

A detailed study of the alkaloidal content of the Formosan Stephania sasakii (Menispermaceae) has led to four new aporphines stesakine (4), dehydrostesakine (5), dehydrocrebanine (6),11 and dehydrophanostenine (7).4 Additionally, dehydro-stephanine (8) has been isolated from S. kwangsiensis.12... [Pg.136]

Oxocrebanine (63) is a new natural oxoaporphine, obtained from Stephania sasakii.4 Oxoanolobine (64), another new oxoaporphine, was found in Guatteria melosma12 and Telitoxicum peruvianum.73... [Pg.148]

Several new alkaloids of these groups have been reported. The new aporphines are steporphine (54) from Stephania sasakii, lanuginosine (55), from Michelia... [Pg.117]

In connection with a continuing investigation of the alkaloidal content of rmosan Stephania sasakii, (-)-roeme] have been isolated and characterized. [Pg.173]

Phanostenine, C19H19O4N, was first described by Tomita (44) as obtained from Stephania sasakii Hayata m.p. 210°, [a] — 36.7° (chloroform). It was subsequently isolated from S. capitata (45) and shown to have the above formula. It has one methoxyl and one hydroxyl, and upon methyla-tion with diazomethane affords an alkaloid shown to be Z-dicentrine (m.p. 160-165°) because when admixed with d-dicentrine there was formed the known dZ-dicentrine (m.p. 176°). Phanostenine can therefore have only one of two possible structures, namely, XVI, with one of the two meth-oxyls replaced by hydroxyl. [Pg.129]

Some families like the Cactaceae, Chenopodiaceae and Fabaceae are known to produce simple isoquinoline alkaloids. In the Menispermaceae they are very rare. Up to the moment, the only compounds of this type isolated from plants of this family were coiypalline and thalflavine from Menispermum dcnmcum, thalifoline from Abutapahni and 6,7-dimethoxy-2-methylisoquinolone from Stephania sasakii. [Pg.40]
