Stephaoxocanidine, a New Isoquinoline Alkaloid from Stephania cepharantha

Noriaki Kashiwaba; Shigeo Morooka; Michiko Kimura; Minoru Ono; Jun Toda; Hideki Suzuki; Takehiro Sano

Abstract Stephaoxocanidine (2), an isoquinoline alkaloid, was isolated from the tubers of Stephania cepharantha Hayata (Menispermaceae) cultivated in Japan. On the basis of spectroscopic evidence, the structure of 2 was established as 12S-6,7-dimethoxy-12-hydroxystephaoxocane. The absolute configuration was deduced by the modified Moshers method.
