Description

Terasaka has isolated this furoquinoline alkaloid from the roots of Orixa japonica and Obata has found that it also occurs in the fruit along with skim_x0002_mianine (q.v.). The alkaloid is optically inactive and is converted by Mel at 100°C into isokokusagine, m.p. 247°C. The aurichloride has m.p. 171°C and the picrate, m.p. 178°C (157°C according to Obata). The structure has been established by synthesis as 7: 8-methylenedioxydictamnine.
