N2  - An extract of the aerial parts of Eriostemon australasius Pers.subsp. banksii (A. Cunn. ex Endl .) P.G. Wilson ( Rutaceae ), collected from the Cape York Peninsula, has yielded four novel secondary metabolites. These were identified, by spectroscopic methods, as methyl (E)-4-(3&#8242;-methylbut-2&#8242;-enyloxy) cinnamate, cis-erioaustralasine [{rel}-1-acetoxymethyl-4,8&#8242;-epoxy-3-(1&#8242;&#946;,2&#8242;&#946;-epoxy-3&#8242;&#946;,4&#8242;&#946;-para-menth-3&#8242;-yl)quinolin-2-one], trans- erioaustralasine [{rel}-1-acetoxymethyl-4,8&#8242;-epoxy-3-(1&#8242;&#946;,2&#8242;&#946;-epoxy-3&#8242;&#946;,4&#8242;&#945;-para-menth-3&#8242;-yl)quinolin-2-one] and furoerioaustralasine [{rel}-2,2&#8242;&#946;:4,8&#8242;-diepoxy-3-(1&#8242;&#946;-hydroxy-3&#8242;&#945;,4&#8242;&#945;-para-menth-3&#8242;-yl) quinoline ]. The structure of cis-erioaustralasine was confirmed by X-ray crystallographic studies. The taxonomic significance of the occurrence of these alkaloids in E. australasius is discussed.
