Separation of the basic fraction from Dehaasia triandra afforded two new bisbenzylisoquinoline alkaloids, dehatridine and dehatrine, along with six known alkaloids, isocorydine, corytuberine, atheroline, nantenine, obaberine and a quaternary aporphine alkaloid, xanthoplanine (5). - Keywords: Dehaasia triandra; Lauraceae; Iau-Guoo-Nan; bisbenzylisoquinoline alkaloids; dehatridine; dehatrine.

Machigline (I), a new phenolic oxoaporphine alkaloid, isolated along with atheroline (II) and β-sitosterol-O-β-D-glucoside from the alcohol extract of the leaves of Machilus glaucescens Wight (Lauraceae), has been shown to be 1,2-methylenedioxy-9-hydroxy-10-methoxyoxoaporphine by spectral and chemical studies.A fatty ketol characterised as a rarely occurring n-hentriacotan-10-ol-16-one (10-hydroxypalmitone) (III); (first report of its occurrence in Lauraceae) has also been isolated as an aliphatic constituent from the CHCl3 extract of the plant besides the lignan and nor-lignan constituents.The mass fragmentation of I and III have been delinated.The isolation of machigline and atheroline constitutes the firsent report on the occurrence of oxoaporphines in Machilus species, and machigline adds a new name to the list of only a few phenolic oxoaporphines.
