“…petiolaris, all yielded 1,3-dihydroxy sapogenins, these usually being the major compounds. This was the case also with C. cannifolia (3)(4)(5). However, although C. australis extract contained the 1,3-dihydroxy compound, brisbagenin, it was not the major sapogenin.…”

“…The steroidal sapogenins yielded by C. cannijolia leaves have been extensively studied; and cordylagenin { (255)-5a-spirostane-l/3,3a-diol}, its 25R epimer cannigenin, brisbagenin ( (25i? )-5a-spirostane-l/3,3/3-diol}, yamogenin { (25S)-spirost-5-en-3d-ol;, 3-e/h-neotigogenin { (25S)-5a-spirostan-3a-ol}, and its 25R epimer, 3-e/h-tigogenin have been isolated (3)(4)(5)(6). Chromatographic evidence indicated also the presence of ruscogenin { (252?…”

“…430 showed in the IR spectrum the characteristic bands of spirostan sapogenins [19]. NMR spectrum indicated the presence of four methyl groups and discarded the possibility of having a 3-a-hydroxy group because it lacked the signal at 6 4.08 typical of that configuration [20]. The mass spectrum fragmentation showed that the compound was substituted in ring F by a hydroxy group (ion a t m/e 155) [21].…”

1-Acetyl-3-Carboxy-β-Carboline, a New Acid and Other Constituents of Vestia lycioides

et al. 1980

From aerial parts of Vestia lycioides, Fam. Solanaceae, endemic to Chile, several secondary metabolites were isolated : two pentacyclic triterpenes, 8amyrin and oleanolic acid; one simple coumarin, fraxetin, a new B-carboline acid, 1-acetyl-3-carboxy-p-carboline, and two steroidal sapogenins, one of them identified as diosgenin. The isolation of some of those metabolites is noteworthy to point out the relationships of Vestia with other genera of the Solanaceae.

“…In the nmr spectrum, the resonances of the secondary and tertiary methyl groups were unresolved and were observed as broad singlets at 0.72 and 0.76. A signal at 4.02 (1H, m, W^-8.0 Hz) was assigned to a hydroxy group at C-3 with an axial conformation (1,3,7,8). Jones' oxidation of A-ll gave a compound mp 215°( literature value (9) for neotigogenone 211-214°), the ir spectrum of which showed strong absoprtion at 1715 cm-1 (carbonyl group).…”
