• 개요

  This bisbenzylisoquinoline alkaloid is found in the benzene-soluble portion of the total alkaloids extracted from Magnolia fuscata. When recrystallized from C6H6 it yields fine, colourless needles, soluble in alkalies, CHC13 and EtOH. It is dextrorotatory with [α]_D + 111.6° and yields a crystalline picrate, m.p. 142- SoC (dec.); a picrolonate, m.p. 163-4°C and a tetramethyl ether, m.p. lSI-2°C. The latter may be oxidized by KMn04 in Me2CO to give 1-keto-6:7-dimethoxy- 2-methyltetrahydroisoquinoline, m.p. 124-5°C and magnolaminic acid, C16H1407, m.p. 280-loC. The alkaloid acts as a cardiac depressant at between 10 to 500 parts per million.
