lasiocarpine Chemical Properties,Usage,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

colourless to beige crystalline solid

Uses

Lasiocarpine is a hepatotoxic and carcinogenic food contaminant.

General Description

Colorless plates or beige crystalline solid.

Air & Water Reactions

Decomposes slowly on standing in air at room temperature. Insoluble in water.

Reactivity Profile

lasiocarpine is readily hydrolyzed by alkali. Reacts readily with oxidizing agents. Reacts slowly with atmospheric oxygen .

Health Hazard

ACUTE/CHRONIC HAZARDS: When heated to decomposition lasiocarpine emits toxic fumes of nitrogen oxides.

Fire Hazard

Flash point data for lasiocarpine are not available; however, lasiocarpine is probably combustible.
