N2  - A further extraction of the bark of Eupomatia laurina R.Br. has yielded 16 substances: liriodenine (as before), norushinsunine, three new bases, benzoic acid, sitosterol, eupodienone-1 (previously EL2; but not EL3 which is an artefact from EL2), eupomatene (ELl), and seven related substances.     The last eight substances, which are closely related, ere named ?eupomatenoids?. The structures of the eupomatenoids -2 to -8 have been established. Like eupomatenoid-1 (eupomatene), they are derivatives of 3-methyl-2-phenyl-5-(E)-propenylbenzofuran and are classified as lignans.
