Two novel minor quinolizidine alkaloids 4 beta-hydroxy-13alpha- O-(2'-pyrrolylcarbonyl)-lupanine (digittine) and its amino alcohol, 4 beta, 13alpha-dihydroxylupanine, have been isolated from Ethiopian Calpurnia aurea ssp. aurea. The structures of these alkaloids were determined by chemical transformation and by means of spectroscopic techniques (UV, IR, CD, MS, (1)H-NMR and (13)C-NMR) including two dimensional NMR.
从埃塞俄比亚的 Calpurnia aurea ssp. aurea 中分离得到了两种新型的微量喹啉生物碱:4β-羟基-13α-O-(2′-吡咯羰基)-羽扇豆碱(digittine)及其氨基醇 4β,13α-二羟基羽扇豆碱。这些生物碱的结构通过化学转化和光谱技术(UV、IR、CD、MS、(1)H-NMR 和(13)C-NMR),包括二维 NMR 来确定。
