A new bisbenzylisoquinoline alkaloid, (+)-limacusine-2'-beta-N-oxide [
1], was isolated from the leaves of Anisocycla jollyana, along with ni
ne known alkaloids: (-)-2'-norlimacine, (-)-2-norlimacine, (-)-limacin
e-2'-beta-N-oxide, (+)-homoaromaline, (+)-trilobine, (+)-isotrilobine,
(+)-dehydro-1,2-telobine, and (+)-remrefidine. The structure of 1 was
established by spectral methods.
