lasiocarpine Chemical Properties,Uses,Production
Description
A hepatotoxic alkaloid found in Heliotropiurn lasiocarpurn, the base forms colourless leaflets from petroleum ether and has [α]20D - 4° (EtOH). It is readily soluble in C6H6 or EtOH but only slightly so in H20. On alkaline hydrolysis it furnishes angelic acid and heliotridine, C8H1302N, m.p. 116.5-118°C, forming a hydrochloride, m.p. 122-4°C and the benzoyl derivative hydrochloride, m.p. 180°C. On catalytic hydrogenation it yields a base, C13H230 2N, b.p. 123-5°Cj 8 mm; [α]D + 3.8° (EtOH), yielding a crystalline picrate, m.p. 157 _9°C, and lasiocarpic acid, C8H160 S, m.p. 95-7°C; [α]D + 10.6° (EtOH). The structure is therefore angelyllasiocarpylheliotridine, both hydroxyls in heliotridine being es terifie d
Chemical Properties
