PROTOVERATRINE B Chemical Properties,Usage,Production

Description

Also present in Veratrum album, this closely allied alkaloid may be separated from the preceding base by chromatography. It also yields colourless crystals from EtOH and is laevorotatory with [α]29D&o - 39.8° (pyridine) or - 3.5° (CHCI3). In this case, alkaline hydrolysis gives protoverine, two moles of acetic acid, one mole of (-)-2-methylbutyric acid and one mole of 2: 3-dihydroxy-2- methylbutyric acid. It may be distinguished from protoveratrine A by giving a green colour with H2S04. It also forms a complex with maleic acid having m.p. 222.2°C; [α]29D&o - 27.3°.
