説明A pyrrolizidine alkaloid obtained from Heliotropiurn supinurn, the base forms colourless needles when crystallized from Me2CO. It has [α]D - 23.8° (EtOH) and on alkaline hydrolysis furnishes trachelantic acid and supinidine. The latter has b.p. 158-9°C/1O mm; [α]D - 9.45° (EtOH) and gives a crystalline picrate, m.p.142-3°C.
使用Supinine is a hepatotoxic alkaloid that is excreted through urine as a metabolic pyrrole.
