[Studies on the chemical constituents of Arisaema fargesii Buchett].

Heptatriacontane, benzoic acid, succinic acid, palmitic acid, stearic acid, beta-sitosterol, stigmasterol, daucosterol, D-mannitol, D-glucose, sucrose and choline chloride were isolated from the roots of Arisaema fargesii collected from Gansu Province. Their structures were elucidated by spectroscopic methods and a few chemical transformations. The twelve compounds have not been reported before as constituents of Arisaema fargesii.
