1,9-Dihydroxy-2,10-dimethoxy-6,6-dimethyl-5,6,6a,7-tetrahydro-4H-dibenzo[de,g]quinolin-6-ium

BeschreibungA quaternary base present in Cocculus laurifolius, the alkaloid has been isolated as the crystalline chloride, m.p. 253°C (dec.); [α]24D + 26.3° (H20). The iodide has also been prepared, this salt having an ultraviolet spectrum containing absorption maxima at 227,281 and 307 mJ1. The (±)-form of the alkaloid yields a crystalline chloride, m.p. 238°C (dec.). The base contains two methoxyl two hydroxyl and one dimethylimino group in the molecule.
