Cassytha alkaloids. II. Alkaloids of Cassytha pubescens R. Br

Abstract
Three aporphine alkaloids isolated from Cassytha pubescens R.Br. have been identified as nantenine, domesticine, and isoboldine, all of which were previously known to occur in Nandina domestica, and a fourth as laurelliptine, an alkaloid of Beilschmiedia elliptica. One other aporphine alkaloid from C. pubescens is new, namely (+)-1-hydroxy-2- methoxy-9,10-methylenedioxynoraporphine (nor-domesticine). A sixth and minor alkaloid from C. pubescens, identified as sinoacutine, the (-)-enantiomer of salutaridine, appears to be the first example of a morphine group alkaloid to be found in the family Lauraceae.
