Duguetia hadrantha

Antifungal alkaloids from Duguetia hadrantha. Muhammad and co-workers reported the isolation and structural characterization of two alkaloids from Duguetia hadrantha, hadranthine-A and -B (82) that were related to the known alkaloid imbiline-I. To confirm the placement of the annular nitrogen atoms in the skeletal framework, the authors utilized long-range HMBC data. Thus, correlations from protons... [Pg.45]

Hadranthine A (XI.10.1), hadranthine B (XI.10.2), and imbiline-1 (XI. 10.3) were isolated from Duguetia hadrantha. This is the first report of dioxoazaaporphine alkaloids from this genus. This appears to be the first report of hadranthine A and B. [Pg.329]

Sampangine (XIV. 187) and 3-methoxysampangine (XIV.144) were isolated from Duguetia hadrantha, this is the first report of the cooccurrence of the copyrine-type alkaloids from a Duguetia species. These compounds were isolated previously from C. odorata of Asian and Cleistopholis patens of African origin, respectively. [Pg.331]
