Jacobine. Chemical Properties,Uses,Production
Description
This alkaloid of the pyrrolizidine group of bases occurs in Senecio cineraria D.C., S. crucifolia and S. Jacobea. It is a laevorotatory base with [α]17D - 46.3° (CHCl 3 ). The alkaloid forms crystalline salts and derivatives, e.g. the hydrochloride, m.p. 220°C; [α]19D - 14.3° (H20); nitrate, m.p. 234°C; methiodide, m.p. 255°C and the picrate, m.p. 180°C which is soluble in H20. The alkaloid contains two active hydrogens and on alkaline hydrolysis yields retronecine and jaconecic acid, ClOH16 0 6, m.p. 182°C; [α]25D + 31.7° containing three O-methyl groups
Uses
Jacobine is a pyrrolizidine alkaloid which has been shown to be an herbivore insect deterrent and may be used in the protection of vegetation. Extracted from Crassocephalum plant of West Africa.
Definition
ChEBI: Jacobine is a pyrrolizine alkaloid.
